Fish Status |
Good | The current crappie population is primarily made up of individuals ranging from 9 - 11 inches in good body condition. | |
Good | The bluegill population was sampled by 30 fish in the fall 2019 electrofishing survey. They ranged in size from 1 to 8.7 inches in length with an average body condition rating of 94. The current bluegill population is rated as very good. A future improvement in the bass population size structure as well as some aquatic vegetation management will help maintain this good bluegill size structure. | |
Good | The channel catfish population was evaluated by 3 catfish ranging from 18 – 21 inches. They had a relative weight value of 99. IDNR will add Brock Lake to the channel catfish stocking schedule starting in 2020. | |
Developing | In 2019, the largemouth bass population was evaluated by 102 bass collected by Pulsed-DC electrofishing. The largemouth bass population appears to be defined by a high percentage of fish from 5 – 12 inches with body condition of 89. We did not collect any bass over 13 inches. The collection rate was 204/hr which indicates a high density. | |
