Fish Status |
Good | The current crappie population is primarily made up of individuals ranging from 9 - 11 inches in good body condition. | |
Good | The current bluegill population is rated as very good with fish over 8 inches present. Aquatic vegetation management will continue to help maintain this good bluegill size structure. | |
Good | IDNR has added Brock Lake to the channel catfish stocking schedule and the first batch of 8-10” catfish were stocked in August 2020. | |
Developing | The largemouth bass population continues to be defined by a high percentage of fish from 5 – 12 inches. Few bass over 13 inches have been collected despite multiple stockings of adult fish. These adult stockings are brood bass that were being retired from Jake Wolf Fish Hatchery. With an average size of 4lbs these fish should provide some great fishing action as well as introduce a larger size class of bass that previously did not exist in the lake. At this time the current bass population could use thinning of bass that are under 12 inches in length. The majority of the current bass population is under approximately 12 inches in length and growing slowly. This is due to a very high density of bass all competing for the same food resources | |
Developing | An initial stocking of redear sunfish occurred in October of 2021. The high density of snails in the lake (a favorite food item of redear) should lead to a good fishery in the near future. In 2024 redear up to 8.6" were collected. | |
