| Species | Rating | Size | Baits, Method, and Location |
|---|---|---|---|
| Black Bass | Fair | 1 to 4 lbs | The smallmouth bass population is on the rebound. The 2024 sample showed the best smallmouth bass numbers in 8 years with a decent size structure as 45% of the fish were over 14" and 7% was over 17". The dam is a great spot to start looking for smallmouth. The lake has maintained a moderate to low level largemouth bass population through the years. The 2024 sample shows the population has improved recently, yet is still at a low level. The East bank, South cove, and around the island are usually the best largemouth spots. |
| White Bass | Fair | Up to 3 lbs | The lake has been maintaining a great white bass fishery but the recent sample shows that their abundance has fallen down to modest numbers with most of the fish being young & small. |
| Wiper | Good | Up to 12 lbs | The 2023 wiper numbers are well above average due to high survival from the 2022 stocking. The majority are still small with 71% of the fish collected in October 2023 were less than 16 inches. Fair numbers of bigger wiper are available with 13% from 16" to 20" and 16% from 20" to 24". Wiper fishing has been great so far this summer! |
| Walleye and Sauger | Fair | Up to 5 lbs | Walleye are maintained through regular stockings and the current population is slightly above average with 83% of the walleye collected being 15 inches or larger. The lake is also home to an emerging sauger population that is growing quickly with 34% of the sauger collected in fall of 2023 were over 15 inches. Walleye and sauger are grouped together in KS regulations and a total of 2 per day can be harvested at the Jeffrey Lakes if they are over the 15-inch minimum length limit. Anglers have been doing well for both species all this year. |
| Crappie | Fair | Up to 1.5 lbs | Crappie numbers have never been robust at this lake but they have been doing better the last few years. The most recent sample had an excellent size structure as 34% was over 12 inches. There is some habitat cubes along the dock and a big brush pile along the point just North of the boat ramp. |
