The original stocking included Largemouth Bass, Bluegill, Red Ear Sunfish, Green Sunfish, Black and Whit Crappie, Channel, Blue and Flathead Catfish, Northern Pike and Yellow Perch. There are White Bass, Warmouth (across of Red Ear and Rock Bass) and Smallmouth Bass - the latter three species coming into the lake via the three forks of Salt Creek. 

Of the original stocking only the Northern Pike did not survive. 

An additional nature stocking occurred when ducks during early spring migration set down in the shallow southern waters picking up fish eggs on their feet then depositing them into the northern lakes; thus, Lake Monroe now has a very healthy supply of bait fish (Yellow Bass and Threadfin Shad).

During the early 1980's the DNR Fish Biologists discovered huge numbers of bait fish and even larger numbers of small bluegill and crappie (actually stunted to the danger point). Which means there were not sufficient numbers of predator fish to eat the smaller fish. 

At this time and thereafter large numbers of walleye and hybrid striped bass were stocked. Everyone is tickled pink with the success. 

For now Lake Monroe has great numbers of large Walleye and Hybrid Bass, plus the lake has large numbers of pound and a half to two pound Crappie. 

The current lake record for the Hybrid Striped Bass is 18.3 lbs. The unofficial record for Largemouth is 11 lb. 2oz.
