Manage as a mixed species recreational fishery for largemouth bass and bluegill. B. Special regulations should be adopted for providing a quality fishery for largemouth bass 12 fish > 15") and to extend the annual yield of bluegill ~ (10 fish bag). III. Stocking purpose and need A. Rationale/Justification for selecting the species ~ 1. Rainbow trout stocking has been moved to one of the larger ponds in the park. Water quality and temperatures are not suitable for holding trout in Island Acres lake except in early spring or late fall. Lake is warmwater fish habitat and managing for warmwater sportfish will provide a year round fishery. 2. Increase fishing opportunity (Long Range Plan Goals 12, 12.1, 12.3). • 3. Largemouth bass and bluegill do not persist in the Colorado River which will minimize impacts to recovery of endangered Colorado River fishes if bass and bluegill escape to the river.
