Lake Claiborne Dam and Adequacy of Spillway Lake
Claiborne Surcharge Reduction Study
Progress Toward Improving the Spillway
2002-2007 History of Contacts to Request
Federal Aid for the Recoinnaissance Study--
Many contacts were made with Senators Landrieu and
Breaux's offices and offers were made to request
inclusion of the reconnaissance study in the federal
budget. In 2007, Rep. McCrery's office announced that a
request would again be made. Below is excerpt of a
CPWD letter dated Sept. 30, 2002 to Senator Landrieu
(Senate Appropriations Committee) acknowledging her
promise to work to include in Federal budget funding for
a US Corps of Engineering Federal Reconnaissnace Study to
explore spillway designs to relieve flooding
problem. Watershed Commissioners followed up on
this course of action. For several years, budget
requests were formally submitted in March.
RE: Landrieu Project No. 111099 attn: Herman
Gesser, III, Projects Director Dear
Honorable Mary Landrieu, We appreciate your
assurance (in letter of September 12) that you will
advocate for inclusion in appropriations legislation of
funding to conduct a U.S. Army Corps of Engineers Federal
Reconnaissance Study to explore spillway designs to
reduce the 100-year storm surge for Lake Claiborne. We
understand that if inclusion in the Fiscal Year 2003
Energy and Water Appropriations Bill is not possible at
this late stage, you will continue to work for the
inclusion of our proposal in the Fiscal Year 2004
legislation. We will appreciate your keeping us
informed about developments concerning our request. ...'

FLOODING:
Important Considerations:
- The
design of Lake Claiborne's spillway is such that
opening the gates will not control a rising lake
level when the rising level threatens to affect
lakefront property. Lake Claiborne is not a flood
control lake. The gates are designed to lower the
lake for lake maintenance only. See DOTD material
in Watershed District files for more information.
- Lakeshore
residents are advised to build with the flood
potential in mind. DOTD has a standing request to
the Watershed District to issue this advice on an
ongoing basis.
Engineers have calculated the expected rise in Lake
Claiborne water level during a storm for different
scenarios (many assumptions are made, so the calculations
yield estimates only):
- "Design
storm" discharge (based on 15" rainfall
in 24 hours, considered the worst storm possible)
would result in a rise in the water level of Lake
Claiborne 13 feet above the lake's normal pool
level.
- "100
year storm" discharge (10" rainfall in
24 hours) would result in a 6.3 feet rise in lake
level.
- "25
year storm" discharge would result in a 4.6
feet rise in lake level.
- "10
year storm" discharge would result in a 3.5
feet rise in lake level.
- Discharge
from an actual storm in 1991 resulted in a 7.2
feet rise in the level of Lake Claiborne above
pool level.'
(see Lake
Claiborne Surcharge Reduction Study)
At the northern end of the dam, there is an all
earthen structure (without impervious core) lower than
the dam's height, designed as an emergency spillway in
the event of the "probable maximum
flood." This spillway would provide water
outlet only when the lake level rises to approximately 11
feet above normal pool level. (see Lake
Claiborne Surcharge Reduction Study)

did not approve Watershed District's request for

repairs. There
were many problems with this drawdown.
Downstream landowners complained of flooding
(unusually heavy Oct. rains), so DOTD slowed rate
of water release; contractors complained they
could not complete deep water pier renovations,
so rate was increased; end date was extended to
Jan. 31 (vs Jan 15 planned) but proved to be
unnecessary because gates were closed on Jan. 7
due to excessive (~9 feet) lake lowering (faulty

Other information on Drawdowns:
- Drawdowns are used to promote aquatic habitats and
fish populations, but an untimely or excessive one can
interfere with the same. LDWF suggested Labor
Day to Jan. 15 as the ideal time and a 5' to 6' level
drop to satisfy public demand while not compromising
aquatic life (Commission's March 8 minutes)
- DOTD operates drawdowns deferring to LDWF for timing
to protect aquatic life; Commission may seek concurrence
of LDWF before requesting DOTD or may ask LDWF to request
DOTD.
- In 1997, LDWF recommend against lowering Lake
Claiborne for flood control on the grounds that the
control gates were not designed for this purpose (April
1997 Commission minutes);
- Commission considered prerelease (winter lake
lowering in anticipation of spring flooding). LDWF
reported that such action might harm largemouth bass and
possibly crappie reproduction. (1998 minutes)
- RESOLUTION FOR ROUTINE DRAWDOWNS OF LAKE CLAIBORNE
June
20 2002 Meeting Minutes recording Draft Resolution for
Routine Drawdowns of Lake Claiborne and discussion of the
resolution.
Adopted by Claiborne Parish Watershed District
Commission on June 20, 2002
WHEREAS, the Commission is charged by state statute
with the care, management, and control of Lake Claiborne
with the purpose, among others, to prevent destruction of
property; and is also charged by state statute to
cooperate with state agencies in the maintenance and
operation of Lake Claiborne dam; and
WHEREAS, over the years the Commission has received
citizen complaints that drawdowns for routine lakeshore
property maintenance are arbitrarily scheduled and often
conducted without sufficient notice to arrange for
repairs, and
WHEREAS, a seven foot drawdown, at a rate of 3"
to 4" per 24 hours, initiated the week after Labor
Day and ending by January 15, has been successfully
accomplished in the past and is considered reasonable,
and
WHEREAS, the Department of Transportation &
Development controls the gates of Lake Claiborne spillway
and the department, before initiating a drawdown, seeks
the assurance of the Department of Wildlife and Fisheries
that aquatic life will not be seriously harmed, and
WHEREAS, the Department of Wildlife and Fisheries has
advised drawdowns no more frequently than every eight
years, except for urgent reasons, and
WHEREAS, Department of Transportation and Development
engineers have stated that Lake Claiborne dam was
designed to allow for drawdowns for shoreline repair and
have written, in June 2002, that the gates of Lake
Claiborne dam are "in excellent condition and could
be utilized without mishap for a drawdown,"
and WHEREAS, the last regular drawdown was six
years ago with a short drawdown three years ago,
NOW THEREFORE BE IT RESOLVED, that the Commission
issue a written request to the
Department of Wildlife and Fisheries with the
following recommendations:
1) that a drawdown of Lake Claiborne be
scheduled every eight years for the purpose, among
others, of routine maintenance of property along the lake
shoreline,
2) that for such regularly scheduled drawdowns,
the lake be lowered a maximum seven feet below pool stage
at a rate of 3" to 4" per 24 hours, with
emphasis on the word maximum' to state that the
lake should be lowered only to the level that would meet
goals and be consistent with Dept. Of Wildlife and
Fisheries requirements,
3) that such drawdowns be initiated during the
week after Labor Day and ended before January 15,
4) that in the event of an interval drawdown
conducted for urgent reasons, such as aquatic life stress
or widespread property damage after a major storm, the
every eight year schedule should be resumed eight years
after that urgent drawdown,
5) that any commission request for an urgent
drawdown have the consent of six of the seven
commissioners, and
6) that scheduled drawdowns begin in the fall of
the year 2004, which is eight years after the last full
drawdown in 1996, assuming agreement of Dept. Of Wildlife
and Fisheries with respect to the impact on aquatic life,
and of the Department of Transportation and Development
with respect to the condition and operability of the
gates for a drawdown at the time.
Note: Discussion at the June, 2002,
meeting included the following observations: 1) based
upon one Lake Claiborne drawdown experience, with every
drawdown there is risk, however small, of operation
failure with devastating sequelae; 2) (from DWF's James
Seales) the effect of Lake Claiborne drawdowns on the
fish population has been difficult to determine,
possibly, in part, because drawdowns have been relatively
frequent; 3) (from WLF's James Seales) a drawdown
of 5 or 6 feet generally would not be expected to
seriously compromise aquatic life but that a 7 foot
drawdown would begin to expose important lake bottom.
As of 2007, Dept. of Wildlife and Fisheries has
declined to act upon the request made through the above
resolution.

FISHING
Historic Timetable and Fishing on Lake Claiborne
1974: Lake Claiborne was selected as a Louisiana
impoundment to be stocked with striped bass
1987 (May): LDWF netting yielded mostly hybrids,
then German carp, then large channel
catfish
1988: Commission agreed that striped bass be
returned to lake, at LDWF's request
$4000 for channel catfish
LDWF: Lake Claiborne was chosen for Intensive Lake
Management 1/89-1/90
100,000 disease-free catfish were stocked
1992: Accepted stripers
Purchased 100,000 catfish fingerlings
1993: Stocked stripers
Commercial netting forbidden because:
1) channel catfish are
expensive, difficult to raise, & susceptible to
netting and
2) Commission had spent
$29,225 stocking 412,000 channel catfish
1997: LDWF won't stock striped bass, including
hybrids, at Commission's request
Later, at citizen request to reconsider prohibition,
Commission agreed to return
to LDWF all considerations regarding stocking of
plants and animals in Lake Claiborne
2002: Feb. 4 Watershed Commission stocked 68,000
catfish fingerlings-LDWF
recommendation
May 3, LDWF stocked the lake with 70,000 Florida bass
fingerlings
May 6, LDWF stocked the lake with 65,000 (or 68,000?)
Hybrid striped bass fingerlings
2007: May 4, LDWF stocked the lake with approximately
69,984 Florida Largemouth Bass fingerlings
May
17, LDWF stocked the lake with approximately 68,608
Hybrid Striped Bass fingerlings
Fall
-- LDWF stocked the lake with Channel Catfish fingerlings

Penzold and Kittler Study: Summary (Reference
Above: #1'Studies of Fishing on Lake Claiborne')
In 1998, the Claiborne Parish Watershed Distric
Commission requested a study (1-Pezold: see
Studies' below) of water quality and fish
production in Lake Claiborne. Findings of that
study and other from sources are presented here.
Lake Claiborne, like most reservoirs associated with
small watersheds on Gulf coastal plains is an
oligotrophic lake: low alkalinity, slightly acidic soft
water, soils nutrient poor & low in calcium.
- low calcium negatively affects alkalinity, a
measure of buffering capacity, i.e. capacity to maintain
a constant pH of lake water (e.g. in past, heavy rains
have lowered pH on Lake Claiborne)
- calcium is a necessary element for aquatic
life; low calcium is an index of low nutrients in
general
Fish production in Lake Claiborne , esp. of large
mouthed bass, is relatively low .
- total fish production averages 131.6
lb./acre2 (highly variable by year and site)
- largemouth bass production averages 9.75
lb./acre (rotenone assays 1970-1989, LDWF data)
- all life stages present, including larval,
i.e. well- established in Lake Claiborne
- low productivity at all life stages because
of:
1) water quality of the lake
2) prefer as prey
structure-oriented forage fish, not shad, an open-water
fish that makes up 78% of adult fish biomass (Lake
Claiborne, 1994)
3) shad consume nutrients otherwise
available for largemouth bass
- hybrid striped bass were introduced to use
nutrients lost to largemouth bass
Authors of the study recommended increasing lake
fertility by manipulating lake water levels, planting a
cover crop on exposed lake bottom. Dropping the
lake level allows new vegetation on the exposed lake bed,
taking up nutrients locked in the sediment.
Reflooding releases nutrients from decaying
vegetation. Infrequent but extreme drawdowns are
usually recommended (authors suggest annual or biannual),
because more frequent drawdowns can decrease forage for
certain species and leave a fluctuating zone unsuitable
to all species. Small annual drawdowns (20% of lake
substrate) have been used successfully. Seasonal
timing is most important. Low and fluctuating water
levels in spring and summer compromise near-shore
spawners (shiners, white crappies -- perch), vegetation
spawners, and young-of-year, e.g. bass.
