Fish Status



33 Black Crappie ranging from 6.3-9.4” were collected in 2017. Like the White Crappie, the 2017 CPUE was the highest catch rate recorded.Historic surveys (1999, 2002, 2007, & 2013) during this 20-year period yielded between 4-19 fish per hour. In 2017, 72.7% of fish exceeded 8”, 6.1% of which measured greater than 9”. The largest fish measured 9.4” and weighed 0.37lbs. Black Crappie relative weights (Wr=87) were poor, like previous years.



Three Channel Catfish were collected, measuring 16.9-26.4”. Body Condition was excellent. Channel Catfish were stocked in 2017 and 2019. IDNR will continue to stock Channel Catfish as hatchery production allows.



Hybrid Striped Bass samples tend to be low using electrofishing equipment. Two Hybrid Striped Bass were collected per hour in 2017. These fish measured 9.8” and 12.2”. Hybrid Striped Bass are periodically stocked as hatchery production allows.



In 2017, 87 Largemouth Bass ranging from 4.3-21.7” were collected. 19.7% of Largemouth Bass collected were 15” or greater. The largest fish measured 21.7” and weighed 5.84lbs. Fish less than 6” (16 fish) were collected, suggesting that natural reproduction is occurring. The catch rate of 87 bass/hour surpasses the catch rate goal (≥60 bass/hour). Structural indices are in good shape and this lake should continue to offer excellent bass fishing.


Very Good

49 White Crappie ranging from 4.3-12.2” were collected in 2017. The 2017 CPUE s the highest catch rate of White Crappie recorded in the last 20 years. The 2002 White Crappie catch rate comes in as the 2nd highest CPUE at 38 fish per hour. Three other surveys occurred during this 20-year period and White Crappie catch rates yielded between 17-31 fish per hour. In 2017, 64.6% of fish exceeded 8”, 8.3% of which measured greater than 9”. The largest fish measured 12.2” and weighed 0.85lbs. Relative weights of White Crappie were excellent in 2017 in comparison to previous years.
