Status of the Fishery (as of 07/20/2009)

The most abundant species sampled in Crooked Lake were bluegills. They were found in above normal abundance but below average size. The average sampled bluegill length was only 5.11 inches. Slightly over 30% of the bluegills sampled were larger than 6 inches in length. Black crappies were found in moderate numbers, but their sizes were also small. Northern pike were found in low abundance during this survey. Walleye numbers have increased since the 2004 assessment. Their numbers are now in the normal range for this type of lake. Channel catfish abundance has also increased. Channel cats exceeding 25 inches were caught. Largemouth bass were found in average numbers with some quality sized individuals.
