EXECUTIVE SUMMARY
Lake Taneycomo was formed by the construction of Powersite Dam (Ozark Beach Dam)
in 1913 and is Missouri's oldest hydroelectric reservoir. It is owned and operated by
Empire District Electric Company (EDEC). The lake is riverine in nature, 22 miles in
length, and encompasses 2,080 surface acres. Prior to 1958, Lake Taneycomo supported
one of Missouri's best warm-water fisheries. This changed in 1958 when Table Rock
Dam, located in the headwater of Lake Taneycomo, began discharging cold hypolimnetic
water into Lake Taneycomo. The discharge of cold water changed Lake Taneycomo into
a cold-water environment, providing good conditions for trout. Rainbow Trout were first
stocked into Lake Taneycomo in 1958. Brown trout were first stocked in 1980. Since
that time more than 30 million Rainbow and Brown Trout have been stocked. Lake
Taneycomo is Missouri's largest and most popular trout fishery, but it also contains an
excellent warmwater fishery in the lower sections of the lake. It annually receives in
excess of 140,000 fishing trips and anglers catch an estimated 500,000 trout annually.
The Missouri Department of Conservation (MDC) coordinates fisheries management
activities following the lake management plan that was updated in February 2010.
A spring electrofishing survey was conducted in the lower portion of Lake Taneycomo
on May 8, 2014 with water temperatures ranging from 65 to 72 degrees F. Largemouth
Bass and Bluegill were the primary species sampled in 1.96 hours of electrofishing. The
2014 Lake Taneycomo trout electrofishing survey was conducted September 4, 2014.
With the cooperation of the Corps of Engineers and Southwest Power Administration,
hydropower releases were terminated at 1900 hours and sampling began at 2100 hours.
A crew of 20 Missouri Department of Conservation staff from Fisheries, Private Lands
Services, and Forestry all assisted with the sample. Sampling was completed by 0130
hours on September 5.
Rainbow Trout
Rainbow Trout were captured at a rate of 202 fish per hour in all zones combined, well
within the range of normal variation (Table 1, Figure 1). Size structure continues to be
good with PSD13 and PSD16 values of 57% and 9%, respectively. Body condition of
Rainbow Trout remains good with relative weights averaging 98 for all sizes (Table 2).
Rainbow Trout were collected at a rate of 225 fish per hour in the special regulation zone
above Fall Creek (Table 3, Figure 2). In this same area, PSD13 and PSD16 were 60% and
9%, respectively and well within the established management objectives (Appendix A).
Size structure has remained steady and fluctuated very little in this area during the past 17
years following the regulation changes, indicating that the regulations are working.
Rainbow Trout were collected at a rate of 94 fish per hour below Fall Creek (Table 3,
Figure 3). PSD13 and PSD16 values were 17% and 0% respectively in this stretch, and
closely resemble that of a put and take fishery. A total of 708,619 Rainbow Trout were
stocked into Lake Taneycomo in 2014 (Table 4).
Brown Trout
The catch per unit effort (CPUE) of Brown Trout was only 36 fish per hour, which is
higher than in 2009-2011, but lower than the previous two years (Table 5, Figure 4). Size
structure of Brown Trout was good with PSD13 and PSD16 values measuring 79% and
44%, respectively. PSD20 of 12% is well above the established management objectives
and signifies that the increased stockings of Brown Trout following the floods of 2008
and 2011 have finally brought the numbers of legal sized fish back into the population.
Body condition of Brown Trout was well above average with an average relative weight
of 115 for all sizes and 124 for Brown Trout greater than or equal to 16 inches (Table 6).
The increase in stocking of Brown Trout from 10,000 to 15,000 in the past four years has
contributed greatly to the rebound of this fishery and should be continued in 2015 as fish
are available. The biggest Brown Trout collected in the 2014 trout sample measured 29.0
inches and weighed 20.8 pounds (Figure 5). A total of 10,007 diploid Brown Trout were
stocked into Lake Taneycomo in 2014.
A total of 5,089 triploid Brown Trout were stocked in 2014 as part of the 15,000 fish
commitment, bringing the total number of triploids stocked into Lake Taneycomo since
2013 to 10,089. Only 33 triploid Brown Trout were captured during the 2014 trout
sample with PSD13 and PSD16 values measuring 50% and 8%, respectively (Figure 6). It
is unknown why so few triploid Brown Trout were captured in the trout sample, but may
be attributed to the lack of reproductive potential of these fish making them remain in the
lower sections of the lake where sampling is not conducted. An additional 5,000 triploid
Brown Trout are planned to be stocked in Lake Taneycomo in 2015 as part of this
ongoing study.
Additional Brown Trout length and weight data was collected from fish ascending the
ladder at Shepherd of the Hills Fish Hatchery in the fall of 2014. The size distribution of
Brown Trout ascending the fish ladder closely resembled that of Brown Trout collected
during the trout sample on Lake Taneycomo, with the exception that few of the Brown
Trout stocked in 2014 (9-11 inches) ascended the fish ladder (Figure 7). Collecting this
data in the future should provide quality supplemental data to the electrofishing samples
greatly help inform future management decisions regarding the Brown Trout population
in Lake Taneycomo. Additionally, collecting this data could provide a cheap and
effective method to assess the status of the Brown Trout population in Lake Taneycomo
during years such as 2014 when electrofishing catch rates of Brown Trout were relatively
low.
Largemouth Bass
A total of 219 Largemouth Bass were captured in 1.96 hours of electrofishing for a CPUE
of 112 Largemouth Bass per hour (Figure 8). Size structure of Largemouth Bass was
excellent and exceeded the established management objectives with PSD12 and PSD15
values were 79% and 39%, respectively. Relative weight of Largemouth Bass was
excellent as well averaging 97 for all sizes (Table 7).
Bluegill
A total of 340 Bluegill were captured in 1.96 hours of electrofishing for a CPUE of 173
Bluegill per hour (Figure 9). Size structure has remained relatively consistent each year
since 2009 that sampling has been conducted. The PSD6 value was 30% in 2014 and
right in line with the established management objectives.
Crappie
Black Crappie were caught via angling in February 2014 and otoliths were taken for age
and growth analysis. The length frequency distribution of Black Crappie caught was
favorable and varied among several different size classes (Figure 10). Otolith
examination of 46 fish indicated that Black Crappie grow well in Lake Taneycomo and
average 10.2 inches at age 4 (Table 8).
General Lake Activities
The low dissolved oxygen (DO) season in 2014 was not nearly as severe as it was in
2013. The low DO season began on August 19 when DO levels dropped below 6 mg/L
in the tailwater of Table Rock Dam and the vacuum breaker vents were opened.
Dissolved oxygen conditions began to improve on November 18 and the vacuum breaker
vents were closed at Table Rock Dam on December 17. No fish mortality was reported
in 2014 as a result of low DO conditions.
Aquatic vegetation treatments were conducted on lower Taneycomo at Empire Park and
Rockaway Beach on June 3, 2014. With MDC providing advice and logistical support,
Midwest Lake Management, Inc. treated several submergent species of aquatic vegetation
including: Curlyleaf Pondweed, Coontail, Southern Naiade, and Elodea by using a mix of
Tribune® and Cutrine Plus®. This was the second year of treatments at Empire Park and
the first year of treatment at Rockaway Beach. Treatments were highly effective at
killing the vegetation in both areas, but seemed to be slightly more effective at Empire
Park following the second year of treatment (Figures 11-12). Empire District Electric
Company (EDEC) staff plan to hire Midwest Lake Management, Inc. again in the spring
of 2015 to treat the vegetation as it begins to grow and will likely continue treatments in
the future to keep the plants under control. MDC and EDEC also worked together to
compose a set of guidelines for the general public to use for treatment of the aquatic
vegetation in Lake Taneycomo (Appendix B).
Management Recommendations
1) Collect trout population information annually for regulation, monitoring, and
triploid study evaluation.
2) Continue to stock 700,000 Rainbow Trout and 15,000 Brown Trout annually,
including 5,000 triploid Brown Trout annually through 2015.
3) Work with MDC Resource Science Division to develop a plan to document the
effects of low DO levels and trout mortality during the low DO season.
4) Cooperate in ongoing efforts to monitor and enhance water quality and flow
regimes.
5) Continue efforts through education of boaters and anglers to prevent the spread of
zebra mussels, Didymo geminata, and other aquatic nuisance species from and to
Lake Taneycomo.
6) Review and comment on permit applications for boat dock construction and
dredge and fill activities.
7) Provide advice and logistical support to EDEC and other stakeholders related to
nuisance aquatic vegetation problems on Lake Taneycomo.
