Fish Status



The Bluegill population is dominated by fish in the 3–6-inch range. Size distribution of the Bluegill population has been moving toward larger fish with increased aquatic vegetation treatments.



Black and White Crappie are both present in Johnson Sauk Trail. White Crappie are the dominate species. Quality fish can be found for both species, but in very low density. Most fish will be less than 8 inches. The lake has no size or creel limits on this species. and they do need to be harvested to improve the fishery.


Very Good

The Largemouth Bass population continues to have a good population structure that will provide for quality fishing with a chance for a trophy size class fish. Numbers of 15—20-inch fish have been steady.



Muskie are stocked every third year. Fish in the 33-38 inch range will be the dominate size class. Fish above 42" do show up regularly in samples.
