Lake Ouachita Fisheries Management Plan Mission Statement:
Provide quality fishing opportunities for all sportfish species in Lake Ouachita through
habitat improvement, fishery enhancement, and increased angler involvement and communication. Conduct fishery management through an
open public process that adapts to changing conditions and seizes new opportunities as they occur.
Introduction
Lake Ouachita is a 40,000-acre Corps of Engineers (COE) reservoir near
Hot
Springs in western Arkansas. Its primary project purposes are hydropower and flood control. The reservoirs sportfisheries (black
bass, crappie,
striped bass,
walleye,
catfish, and
bream) are managed by the Arkansas Game and Fish Commission (AGFC) under the authority of
Amendment 35 to the Arkansas Constitution.
To better understand and address the overall desires of the Lake Ouachita fishing public, AGFC contracted an
independent facilitator to assist with developing an all-inclusive fisheries management plan for Lake Ouachita. Dynamic Solutions Group (DSG),
an independent consulting firm, was retained to facilitate the process. Their agent, Mr. Spencer Amend, was the primary facilitator for the plan
development.
Purpose of the Plan
The plan was developed to address, as extensively as possible, the desires and expectations of the fishing public of Lake Ouachita in regards to
the overall management of the lakes sport fishery. The deliverable elements of the plan are based on scientific fisheries management principles and are intended to maintain and enhance the wide variety of
fishing options available on Lake Ouachita.
Development of the Plan
AGFC Fisheries Division identified a group of Lake Ouachita stakeholders in
regards to their interest and availability to serve on an oversight
committee. A
Lake Ouachita Citizens Advisory Group (LOCAG)
was formed during July 2006 to help the Commission with formulation of the management plan. A charter (see LOCAG Charter in appendices) was proposed by DSG and adopted by the LOCAG to direct their work. Guiding principles in the
Charter for LOCAG members were:
a. Represent and provide perspectives of all anglers who fish Lake
Ouachita and others who have an interest in Lake Ouachita fisheries
resources.
b. Assist in the completion of the Lake Ouachita Fisheries Management
Plan.
c. Advise and assist with the implementation of the Lake Ouachita
Fisheries Management Plan.
d.
Help evaluate the success of the Lake Ouachita Fisheries Management
Plan.
e.
Provide information and perspectives to help with needed
modifications to the Lake Ouachita Fisheries Management Plan.
Original Draft Lake Ouachita Fisheries Management Plan.
The first draft of the Lake Ouachita plan proposed goals, objectives, and
strategies for Lake Ouachita with consideration of public input and fishery
science. Public comments were collected during two August 2006 facilitated
public workshops held in Mount Ida and Fountain Lake. These meetings were
advertised to the public and their participation was encouraged. The
Commission updated its website to include information regarding the LOCAG
meeting in August as well as reports detailing the input from both public
meetings. Additionally, the public had a website link to submit their advice
and comments. Preliminary outlines of management plan strategies were
circulated among the LOCAG for advice. Fisheries management personnel then
incorporated that advice into the original draft management plan document.
Final Draft Lake Ouachita Fisheries Management Plan.
The original draft Lake Ouachita Fisheries Management Plan, dated October 17,
was distributed first to the members of the LOCAG and thereafter by mail to the attendees of the first two workshops with known addresses and through
the AGFC website to the general public.
Numerous comments and suggestions concerning the original draft management plan were
received during the third, and last, facilitated public workshop (held at Lake Hamilton High School in November 2006) and from those who replied to a
follow-up survey questionnaire that was distributed in November 2006 to over 200 individuals who had been active in the management plan development
process. This final draft incorporates many of the comments and suggestions received from all sources during this public process. Copies of these
comments and suggestions will be included as an appendix to this document.
Organization of the Lake Ouachita Fisheries Management Plan
For organizational purposes, the plan is divided into
the three (3) major categories that relate to the major components of
any fishery: People, Fish, and Habitat.
Achieve Lake Ouachita fisheries management goals and objectives in an open and transparent process involving all anglers, the Corps of Engineers, U.S.
Forest Service, Entergy, and fishing-related businesses.
Objectives
A.
Interact annually or more often as needed with the LOCAG. Update meeting held March
4, 2010.
B.
Maintain an interactive informational website.
C.
Determine angler satisfaction and preferences through anangler creel survey. Began December, 2007. 3 - Year creel survey
to continue through end November, 2010.
D.
Maintain open lines of communication/cooperation between other state and
federal agencies.
E.
Encourage anglers to participate in fish management activities such as fish stockings, habitat improvement projects, and fish sampling. ABBC assistance in stocking
bass. Samates made available to LOCAG. Received assistance with all
2009 bass stockings.

on the fishery management of Lake Ouachita. ABBC September, 2007, June, 2008
HSV
Anglers May, 2008,
HS Lions Club August, 2009.
G.
Work with AGFC Communications Division to develop informational
outreach on Striped Bass, Black Bass, Best Fish Handling Practices, Aquatic
Vegetation Control, and other topics of interest to improve angler
understanding of the ecological and social parameters effecting Lake
Ouachita fisheries.
H.
Actively solicit feedback
from the public on the condition of the fishery. Creel Survey opportunity and Fishing
Regulations meetings in May.
III. Maintain Enforcement efforts to reduce the impact of fishing
violations on the sportfish in Lake Ouachita.
Objectives
A. Focus Enforcement effort during critical periods.
Strategies
1. Insure Wildlife Officers are patrolling the lake with emphasis on fishing regulations during peak periods.
2. Devote the equivalent of one Wildlife Officer during period of
highest fishing activity (March 15 May 15) to Lake Ouachita only.
3. Continue to visit fish cleaning stations at Crystal Springs, Tompkins Bend, Brady Mountain, etc., regularly.
4. Enhance fishing enforcement efforts during the spawning season.
5. Evaluate the need for and develop special enforcement operation plans for peak angling times on Lake Ouachita.
B. Focus Enforcement effort on fishing activities.
Strategies
1. Increase fishing license checks.
2. Increase checks for compliance with length limits.
3. Increase checks for compliance with possession limits. Wildlife Officers place an
emphasis on enforcing fish regulations on all lakes and rivers while working
waters in our district (Garland, Hot Spring, Montgomery, Yell, Polk and
Saline Counties).
C. Maintain or increase Enforcement emphasis on fishing in Lake Ouachita
during the rest of the year.
1. Increase and enhance year round Enforcement efforts by boat.
2. Utilize special Enforcement operations with angler focus if necessary. Enforcement saturations on Lake
Ouachita during the Memorial Day, July 4th and Labor Day Holiday
weekends. Enforced the spearfishing
regulations using the Arkansas Game and Fish Commission Dive Team and
Helicopter.
Achieve a balanced, quality, and diverse sport fishery using science-based fisheries management principles.
Largemouth bass, the most targeted sportfish and a key indicator of fish community balance, will be the principal management focus for shoreline
fishes.
I. Largemouth bass fishery goal:
Achieve a quality largemouth bass
fishery attractive to anglers.
Management will seek to balance bass density
with improved growth rates commensurate with forage and habitat conditions.
Objectives
A.
Improve size structure and growth rate of native (Northern)
largemouth bass. Specific metrics to achieve:
1. Achieve a Relative Stock Density to 30%. (Note: Relative Stock
Density (RSD) for largemouth bass is the percent of Stock-size bass (all
largemouth bass that are 8 inches long or longer) that are 15 inches long or
longer). 2007 - 19.1% 2008 - 26.0%
2009 - 27.4% Sample
size 530 bass.
2.
Achieve average length-at-age of 16 inches at Age 4+. Spring electro
- fishing
planned for April, 2010 to address growth & genetics.
Strategies
1. Maintain current 13-inch minimum length
limit until adjustments are needed to achieve the above objectives. Continue.
2. Maintain current 6 bass per day creel
limit.
Continue.
3. Encourage bass tournament directors to
conduct their events when water temperatures are below 83 degrees.
4. Increase enforcement presence for compliance.
5. Evaluate achievement through annual electrofishing and cove-rotenone
sampling. Cove
rotenone samples planned Summer, 2010 (may be the last).
6. Evaluate achievement through the Arkansas Tournament Information
Program (ATIP). Current ATIP data being
collected and analyzed byBlack Bass Program.
7.
Evaluate achievement through dialogue and discussions with anglers.
Ongoing. Discussions with anglers common
for creel survey clerk.
B.
Improve the catch success of largemouth bass anglers. Specific
metrics:
1.
Achieve at least 0.2
bass/angling-hour catch-rate for largemouth bass over 13-inches as
determined by creel survey (for anglers identifying themselves as black bass
anglers). First yearcreel data 0.181
lmb/hr.
over 13 inches. Creel data from the second
year have not been analyzed yet.
2.Achieve a catch-rate of 600 hrs per largemouth bass over 5 lbs. (Note: as measured by ATIP data, the
average hours required to catch a largemouth bass over 5 lbs. in Lake
Ouachita since 1990 is 627 hours).
2007 383 hours 2008 231 hours 2009 - *248 hours (Prelim.
data, consists of data from 22 tourn.)
3.
Evaluate through a 3-year
creel survey beginning in December 2007. On schedule.
4.
Achieve average weight of 1.85 lbs. per largemouth bass
caught in tournaments (ATIP target).
2007 2.14 pounds per tournament lmb 2008 2.34
2009 - *2.25 (Prelim. data, consists of
data from 22 tourn.)
C.Maintain adequate recruitment rates of young largemouth bass to
sustain a viable, quality bass fishery.
Recruitment age 1 fish.
Strategies:
1. Stock largemouth bass through the
Lake Ouachita nursery pond as part of the three-year rotation. Preferred
method: Hatchery system will stock (40,000) northern largemouth bass
fingerlings into the nursery pond in late May or early June. Fingerlings
will be raised on minnow forage to average of 5- to 6-inch fish before
summer release directly into the lake. (Note: Currently scheduled for
2010 pond crop). Or, natural broodstock will
be secured either through electrofishing or tournament weigh-ins and stocked
directly into nursery pond. All broodfish and fingerlings will be drained
into the lake at time of release. (Note: Wild spawning can be expected to
produce an estimated 250,000 one- to two-inch fingerlings). Culture method
will be at the discretion of District Fisheries Biologist: 2007 - 40,000 yearling size largemouth bass
from N. pond.
2008 - 495,000 fingerling size mixed crappie + broodstock.
2009 - 200,000 walleye fingerlings released.
2010 - 55,000 fingerling
largemouths requested for pond in late May.
2. Stock an additional 60,000 hatchery fingerlings by boat in years when nursery pond is used to raise bass to 5-6 inches, as is planned for 2010. 2007 59,870 fingerling lmb stocked by boat with assistance.
3. Stock 100,000 northern largemouth bass fingerlings by boat in 2008. A total of 604,602 northern largemouth bass stocked in five years from 2004-2008. 2008 101,244 fingerling lmb stocked by boat with assistance.
4. Stock additional largemouth bass fingerlings when cove-rotenone results indicate lower than average spawn success (50% of historic average).
Historic average is 434 lmb young per acre. 2006 - 520 yoy lmb 2007 - 783 2008 - 525 2009 - 117
2009 meets the established criterion. Stocking additional yearling size bass from Nursery Pond 2010.
5. Work with the COE to maintain stable water level during spring spawning season when feasible.
6. Determine relationship between spawning success and the density of Age 1 largemouth bass the following spring.
7. Determine the efficacy of stocking largemouth bass to supplement natural reproduction by bio-marking stocked fingerlings with a long-range
target contribution to recruitment (survival to Age 1) of 15 percent.
D.
Determine the suitability and efficacy of using Florida-strain largemouth bass in Lake Ouachita to improve bass growth performance and the
catch-rate of bass over 5 pounds by anglers.
Baseline genetic data collected in 2007. Rabbittail 97% NLMB, 3% F1 or Fx, 0% pure FLMB Buckville 95% NLMB, 5% F1 or Fx, 0% pure FLMB Brady Mtn. 92% 8% 0% Crystal Springs 93%, 7%, 0% Mtn. Harbor 93%, 7%, 0%
Genetics data is scheduled to be collected in April, 2010.
Strategy
1.Introduce Florida largemouth bass (FLMB) into the Rabbittail/Buckville area of the lake. Stock
93,700 minimum per year for eight years by boat. (Note: This design facilitates genetic evaluation in the Rabbittail arm of the lake). 2007 96,330 FLMB fingerlings stocked with assistance. 2008 100,450 2009 101,550
2. Compare growth differences between largemouth bass within the stocking site with known native strain largemouth bass from other areas of
Lake Ouachita. In year 2010
3. Determine the rate of Florida allele introgression into the native
genome component within the stocking site with a target of 40 percent occurrence of Florida alleles in the study area by the end of the 8-year
introduction effort. First evaluation in 2010.
II. Spotted bass fishery goal: Provide a viable spotted bass fishery
relative to the lakes habitat conditions.
Protect spotted bass adults with 13-inch minimum length limit effective January 1, 2007 2008 electrofishing indicates 79% of Lake Ouachita spotted bass protected by 13-inch mll. 2009 electrofishing indicates 83% of Lake Ouachita spotted bass protected by 13-inch mll.
Sample size 230 bass.
III. Smallmouth bass fishery goal: Establish a self-sustaining population
of reservoir strain smallmouth bass designed to produce a trophy fishery.
Strategies
1 Stock 100,000 fingerling smallmouth bass annually until 2010 in designated stocking zone between Blakely Dam and Point #1. 2006 - 227,168 smb fingerlings stocked with assistance. 2007 - 191,719 2008 - 100,870 2009 - 164,700 2010 - last year of commitment
if production meets target. Since 1997 nearly 780,000 fing. smb + almost
64,000 yearling smb have been released into stocking zone. Also brooders in 2010.
2. Maintain catch and release regulation for smallmouth bass and
discourage anglers from moving smallmouth bass from stocking zone into tributaries. Ongoing
3. Evaluate stocking success through electrofishing, cove-rotenone,
creel census and monitor genetic introgression (the spread of Tennessee-strain smallmouth bass genes) into the native smallmouth bass
populations in the Upper Ouachita River and its South Fork. AGFC biologists conducting SCUBA survey each September document number and size of smb seen. Angler comments
indicate rare catch within and near stocking zone.
Fall, 2009 electrofishing in SMB stocking zone yielded only 2 adult speciments (14 & 16). Abundant young smb observed in September SCUBA & snorkel survey not confirmed by Fall
electrofishing.
IV. Striped bass fishery goal: Achieve a viable and balanced striped bass
fishery. Management will seek robust growth rates focused on providing large
fish at a population density attractive to anglers. Specific striped bass
population metrics:
Objectives
1. Achieve an average length-at-age of 26 inches by Age 4. 2003 year class 26.0
inches at Age 4.
2004 year class 25.8 inches at Age 4. 2005 year class 25.6
inches @ Age 4. small sample
2.
Achieve Relative Weight Index, Wr, of 95%. (Note:Relative weight index (Wr) is the ratio of a fishs weight to the weight of a standard fish of the same length and species. Striped bass
relative weights fluctuate seasonally in reservoirs throughout the U.S. with
summer being typically a time of reduced feeding activity due to thermal
stress and lower dissolved oxygen concentrations). Lake Ouachita Wr
calculations will come from striped bass captured during cooler weather
months prior to gonadal development (October-February). Current Wr is
93.3%.
3. Maintain striped bass angler
catch-rate of 0.10 fish/angling-hour as determined by creel survey (for anglers identifying themselves as striped bass anglers).
First year creel data 0.095 striper /
angling-hour.
Strategies
1.
Stock striped bass as follows:
3 to 4 fingerlings per
surface acre
When Lake Ouachita adult striped bass
average relative weight (Wr) exceeds 95% and length-at-age 4 is
minimum 24 inches. Potential annual stocking: 120,000 to 160,000
fingerlings at discretion of Fisheries Division.
2 fingerlings per surface acre
When Wr is between 95% and 92%
and length-at-age 4 is below 24 inches (annual stocking of 80,000).
Length-at-Age 4 exceeds 24inches with Wr at 93.3%. Recommend 80,000 in 2010.
1 fingerling per surface
acre
When average Wr falls between
92% and 82% (annual stocking of 40,000).
No stocking
When combination of Wr below
82%, other health concerns, and low forage base data will result in no
stocking for one year. Stocking will resume when stocking conditions as
described above are favorable.
Following rare striped bass hatchery production failure resulting in no striped bass being available to
stock and adult striped bass in the reservoir have suitable length-weight condition factors, the stocking rate in the next year will be 3 to 4
fingerlings per acre (120,000 - 160,000). Striped bass stocked in 2007 80,000 Striped bass stocked in 2008 81,292
Striped bass stocked in 2009 100,000
2. Retain 3 fish daily creel limit for striped bass. No change
3. Determine mortality rates of stocked striped bass fingerlings to Age
2 to help estimate stocking success. Study not
funded.
4. Implement an angler diary program with
striped bass guides to collect fishery information. Diaries provided to
some guides.
5. Monitor population through annual gill
netting surveys during spring striped bass spawning projects to
estimate relative abundance.
6. Evaluate striped bass
angler success and harvest rates through creel survey.
Creel Survey harvest first year 5447 stripers weighing average of 10.98 lbs each. No results in 2009 tabulated.
V. Crappie fishery goal:
Support an abundant number of crappies
available for angler harvest. Management will treat both species
of crappie as one
stock.
Strategies
1.
Stocking via nursery pond crop rotation. Stock 15 broodstock per acre or 300 adults for pond spawning
as planned for 2008. 270 mixed brood
crappie stocked into pond Spring, 2008.
495,000 fingerlings released
Summer, 2008.
2. Evaluate through fall electrofishing, cove-rotenone samples, and
creel survey. From
creel survey 21,550 crappie harvested first year. Average weight per crappie was 0.63 pounds.
VI.
Walleye fishery goal: Provide a viable walleye population available
for angler harvest.
Strategies
1. Stock via nursery pond crop rotation in 2009. Stock fry into pond and
raise to fingerling size before release. Estimated release at 150,000 to
300,000 fingerlings.
2.
Surplus hatchery production will be stocked as fingerlings in years
when walleye are not in nursery pond. Estimated 200,000 fingerlings
released from 2009 nursery pond crop (17% survival of 1.2 million fry). Hulsey Hatchery 7- year average 28% survival (fry to fingerling. size).
3. Evaluate through cove-rotenone samples and creel survey.
VII. Catfish fishery
goal:
Provide a viable catfish population available for anglerharvest.
Strategies
1. Annually stock 20,000 catchable-size (12- to 14-inch) channel catfish from Jim Collins Net Pen Facility on Lake Ouachita.
23,037 in 2008 20,710 in 2009. In 2009, 94
reward tags out of 510 tagged catchable size ch. catfish were cashed in. Four tags were valued at $100 each.
3. Stock 5,000 yearling-size blue catfish in 2008.
none stocked in 2008 5,250
stockedin 2009
VIII. Forage fish goals: Maintain self-supporting population of forage
fishes.
Strategies
1. Maintain the current mix of forage fish species (including sunfishes,
minnows, gizzard and threadfin shad, etc.). No new non-native forage
species introductions.
2. Supplemental stocking of threadfin shad is not an option until AGFC
finds an alternate source other than Lake Hamilton. (Note: AGFCs primary
source for threadfin shad is Lake Hamilton but that waterbody has been
infested with yellow bass. To avoid spreading this undesirable species to
Lake Ouachita, no threadfin shad will be stocked until another viable source
for threadfin shad is identified).
3. Evaluate forage fish population through annual cove-rotenone
samples.
Threadfin shad:
17.9 kilograms per hectare in 2007
16.4 kilograms per hectare in 2008 9.0
kilograms per hectare in 2009
4. Explore the efficacy of using hydro-acoustics to improve threadfin
shad population assessments. Not funded Not funded
5. When an effective shad sampling method is developed, use shad population metrics and fish condition indices to help establish stocking
levels for predator sportfish. Considering
option of gill-netting for shad density data.
Achieve the types, quality and quantity of aquatic habitat in Lake Ouachita that will support a healthy, balanced and robust sport fishery.
Objectives
A Manage a mix of submerged aquatic vegetation to achieve no more than
20% of the lakes surface area. Satellite
imagery from 2008 being analyzed forsurface coverage by Corps of Engineers. COE update?
Strategies
A.
Reduce the proportion of Hydrillasp. and Eurasian
water milfoil in favor of more desirable native species. COE site investigations. Obviously reduced in 2009 but still present. Sprigs
seen washed to shore and angler reports.
B. Stock 10,000 yearling grass carp into targeted areas in cooperation
with the COE in 2007. Future grass carp stockings will be based on
Hydrilla sp. coverage with cover data provided by COE Stocked 2,262 in 2007.
C.
Endorse COE use of approved aquatic herbicides in selected areas such
as swim beaches, boat launches, and marinas.
D.
Endorse COE insect bio-control programs.
Provide technical and logistical support for COE native plant
restoration projects.
I. Increase the abundance of woody structure in Lake Ouachita.
Strategies
A. Utilize AGFC habitat barge for placement of woody cover, particularly
in the western portions where aquatic vegetation is limited, beginning in
fall of 2008, according to COE guidelines. Barge moved to Lake Ouachita.
B.
Participate in COE tree-hinging program. COE hinged trees in Hwy. 27 area.
C.
Develop a woody structure
habitat enhancement plan by spring, 2008. Tensites constructed before end of March, 2009 in
Tompkins Bend area. GPS coordinates
available. Plan six additional sites in Avant area March, 2010.
AQUATIC NUISANCE SPECIES STATEMENT
A
multi-member task force is working to develop a comprehensive aquatic
nuisance species plan for the State of Arkansas. The plan will inform and
direct control and management of nuisance plants, animals, and pathogens.
There are members of the LOCAG on this task force. The LOCAG, Corps of
Engineers, AGFC, and other entities will cooperate to implement the plan on
Lake Ouachita when it has been finalized then formally adopted by the
Governor of Arkansas and the National Aquatic Nuisance Species Task Force
(target 2008).
GENERAL STATEMENT ON COLLABORATIVE ADAPTIVE MANAGEMENT
It is the
current policy of the Fisheries Division of the Arkansas Game and Fish
Commission to utilize a form of adaptive resource management as an important
approach for sportfishery management within the state. This is a process
for systematically and continually assessing complex fishery resources,
resource management decisions, and management actions to better obtain
specific objectives and produce best-management practices. This process
also helps provide information that can continually improve management of
the states fisheries. In other words, the division is committed to
constantly assessing and re-assessing the results of management actions and
adapting to these findings or to changing conditions. Therefore, the
objectives and strategies of this plan may be modified as new knowledge or
better science becomes available. Example will be
shad monitoring updates in 2011.
In
collaborative adaptive management, the above process actively includes as
many stake-holders as possible to link a wide range of individual
experiences and values with the actual science and technology of fisheries
management. It is our goal to continue to seek the participation of the
Lake Ouachita Citizens Advisory Group in the on-going assessment and
management of the fisheries in Lake Ouachita.
