Glen Elder District Fisheries Volume 6, Issue 1 Kansas Department of Wildlife, Parks & Tourism Spring 2015 New Fish Attractors for District Reservoirs With the help of over 20 volunteers from the Salina and Hays bass clubs, Kansas Department of Wildlife & Parks staff was able to place 30 of the new Georgia cubes in Wilson Reservoir on March 7th, 2015. These PVC structures are 3 foot cubes with 4 Members of the Hays and Salina bass clubs inch corrugated pipe strung through them that construct 30 Georgia Cubes in March 2015. will provide excellent fish habitat for both young fingerlings and larger adult fish. The target species in Wilson are largemouth and smallmouth bass, but crappie, bluegill, white perch, and catfish will all utilize them. The Georgia Department of Natural Resources designed these habitat cubes and research has shown they will attract fish as well or better than brush, but will last more than three times as long. They also have the benefit of not affecting water quality. Local bass anglers prepare to haul Georgia Members of the Waconda Lake Association cubes to several locations in Wilson Reservoir. worked with KDWPT to help purchase and construct 20 of these cubes for Glen Elder Reservoir. These structures were placed in 8- 10 feet of water in clusters of 10 to provide habitat for the young crappie, largemouth bass, and smallmouth bass in the reservoir. We hope to continue to add more cubes each year to these reservoirs as well as expand to other water bodies. They are cost-effective, The first five Georgia cubes placed in Wilson. simple to construct and easy to deploy. They They will eventually sit in 11 feet of water when will continue to provide many years of benefit the reservoir refills. to the fisheries in these reservoirs and help the angler be more successful on the water. Glen Elder Reservoir 2015 Fishing Forecast Scott Waters—District Fisheries Biologist [email protected] /785-545-3345 General Information: The reservoir is approximately 2.3 feet low as of April 2015. All boat ramps and facilities will be open and usable again this year. Also, be on the lookout for blue catfish which we have stocked each of the last five years. Don’t forget the new 35 inch length limit on blue catfish at Glen Elder! Special Regulations: • Blue Catfish—35 inch minimum length limit • Crappie—Daily creel limit of 20 fish • Walleye—18 inch minimum length limit • Largemouth and Smallmouth Bass—18 inch minimum length limit GLEN ELDER RESERVOIR FALL SAMPLING DATA (2014) Common Relative Abundance (2014 gill nets) Carp, 3% Smallmouth Bass, Flathead Catfish, River Carpsucker, Longnose Gar, 4% 3% 0.6% 0.5% Freshwater Drum, 1% Blue Catfish, 0.3% Channel Catfish, 8% Walleye, 11% White Bass, 43% Gizzard Shad, 11% Wiper, 14% Length (in) Weight (lb) # Caught Average (Range) Average (Range) Black Crappie 4 3.1 3.0-3.3 0.1 0.1-0.1 Blue Catfish* 41 21.0 15.2-24.6 3.5 1.3-6.0 Channel Catfish 50 20.6 13.2-28.5 3.2 0.7-9.6 Flathead Catfish* 226 16.3 4.9-45.2 3.4 0.1-49 Gizzard Shad 73 16.2 10.8-18.3 N/A N/A Smallmouth Bass** 135 11.1 3.8-19.5 0.9 0.1-3.9 Walleye 67 17.0 8.1-24.2 2.0 0.2-4.4 White Bass 274 12.6 4.9-15.9 1.1 0.3-2.1 White Crappie 189 10.7 2.6-13.2 0.7 0.1-1.2 Wiper 91 16.3 13.5-25 2.1 1.4-5.6 *Collected during summer electrofishing **Collected during spring electrofishing GLEN ELDER RESERVOIR FALL SAMPLING DATA (2014) AND 2015 FISHING FORECAST BLACK BASS--GOOD Smallmouth bass numbers were similar to the 2014 sample with 135 fish collected ranging from 4 to 19.5 inches and up to 3.9 pounds. The catch rate of fish over 8 inches increased 42%, however, indicating size structure is getting larger. This was the best catch rate since 2010. Fish between 8 and 12 inches dominated the sample accounting for 54%, fish between 4 and 7 inches were 14%, 13 to 16 inch fish comprised 28% of the catch, and very nice fish between 17 and 20 inches were 4%. The big 2012 year class of smallies is growing well with an average length of 10 inches. These fish will continue to grow and should provide some quality fish in the next 2-3 years. Trophy fish numbers were also improved with the highest catch rate collected since 2010, and these fish should provide some quality fishing. No largemouth bass were collected during the electrofishing sample. Anglers reported catching largemouth between 12 and 18 inches, though, so there are still a few left to supplement the smallmouth catch. Glen Elder ranks among the top five reservoirs in the state for smallmouth bass density (11 inches) and preferred size (14 inches) when compared with the other reservoirs. 18 inch minimum length limit in effect. 16 14 12 10 8 6 4 2 0 3 5 6 8 9 11 12 14 16 17 19 Total Length (in.) ` GLEN ELDER RESERVOIR FALL SAMPLING DATA (2014) AND 2015 FISHING FORECAST WALLEYE--GOOD 7 6 5 4 3 2 Number Collected 1 0 8 9 11 12 14 16 17 19 20 22 23 25 Total Length (in.) The walleye catch rate in 2014 was down 35% compared with the 2013 sample, and 46% lower than the 2012 sample. While the number of walleye in the reservoir is down, there are still good numbers of fish that will provide quality angling in 2015. Anglers should have an equal chance of catching short fish and legal fish as the sample showed a 50:50 ratio is available. Glen Elder currently ranks among the top eight reservoirs in the state in terms of walleye density (15 inches) and preferred (20 inches) size fish. Approximately 42% of the population is between 18 and 21 inches with 26% between 15 and 17 inches, 25% between 8 and 14 inches, and 7% between 22 and 24 inches. Fish condition was good to excellent this past fall due to a very large gizzard shad year class. The 2013 year class (13-15 inches) accounted for 12% while the 2014 year class (8-10 inches) represented 15%. These young year classes are the foundation for continued walleye population growth and should boost this population in future years. The best fishing usually occurs during an 8 week period between late April and June. The fish move to the flats on the west end of the reservoir and can be caught using a variety of methods. GLEN ELDER RESERVOIR FALL SAMPLING DATA (2014) AND 2015 FISHING FORECAST WhitE bass--GOOD 30 25 20 15 10 5 0 5 6 8 9 11 12 14 16 Total Length (in.) Total white bass numbers were 25% lower in the fall 2014 sample while the number of fish 12 inches and bigger was 44% lower. These values represent the lowest recorded in the past 5 years. However, Glen Elder continues to rank among the top five reservoirs in the state for density (9 inches), preferred (12 inches), and lunker (15 inches) size fish. The adult sample consisted of fish between 10 and 16 inches with 47% of the total catch between 13 and 16 inches. Anglers will notice strong numbers of young fish in 2015 with 5 to 8 inch fish representing 39% of the catch. Fish between 10 and 12 inches accounted for 14%. Fish condition was again excellent as the white bass had no problem finding shad this past year. Anglers can try a variety of methods to catch white bass with the spring spawning period up both river forks an excellent bet given adequate inflows. Hot summer days will find whites schooling in open water and chasing shad on the surface while night anglers do very well using floating lights. Fall is often a great time to pull out the slabs and fish along rocky points and other areas, while winter ice fishing may be the best time to catch these guys when they stack up along the river channels. GLEN ELDER RESERVOIR FALL SAMPLING DATA (2014) AND 2015 FISHING FORECAST WipEr--FAIR Wipers were not stocked in 2014 and as a result the catch rates declined 39% compared with the 2013 sample. The fish from the previous two stockings are growing very well, however, with the 2013 fish between 14 and 15 inches, and the 2012 fish between 16 and 18 inches. Overall, the 2014 year class accounted for 63% of the catch, the 2013 year class comprised 22%, wipers between 19 and 23 inches were 14%, and fish over 25 inches were 1%. Anglers reports indicated a few of the original stocked fish (2006) remain and have grown up to 12 pounds, but their numbers are low. Body condition of these wipers is down from last year, but remains good overall. A few large stripers (9-20 pounds) can also be found with ice anglers catching most of them. Stripers were stocked in 2014 and a handful of 8 inch fish were sampled last fall. Anglers can find wipers mixed in with white bass throughout the year, but in general, the wipers tend to occupy the lower end of the reservoir near the dam and hang out in Walnut Creek much of the year. Slabbing over humps, trolling crankbaits, or casting bucktail jigs off 35 windy points are some of the better methods for 30 catching wipers.
