Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.
Bluegills remain the most abundant species in Olson Lake. Their population is considered high when compared to similar lakes. Their size structure remains small. The average length sampled was 4.78 inches. Pumpkinseed, green and hybrid sunfish were all sampled during the survey. The northern pike population was sampled at the second highest level recorded for this lake. The average size sampled was 21.9 inches and 2.41 pounds. Black crappies numbers are moderate, but the size is small. Largemouth bass were sampled in average abundance. This lake continues to be popular with bass anglers. Two walleye were sampled during the survey despite having not been stocked since 2003 in Olson Lake and 2005 in Demontreville Lake, which is connected. Yellow bullhead and black bullhead were each sampled in Olson Lake. Black bullhead were found in low numbers but yellow bullhead were found in average abundance.
