Fish Status



This population is poor. The relative weights are average, but no fish collected exceeded 7”. In lakes where Gizzard Shad are present Bluegill tend to exhibit slow growth due to competition for food resources.


Very Good

Thirteen Channel Catfish were collected in 2020. 33% of the catchable Channel Catfish population exceeded 18”. Eleven Channel Catfish were collected in 2019, ranging from 10.2-14.6”. In 2018, four Channel Catfish were sampled, ranging from 9.4-22.0”. Historically the Channel Catfish population has been excellent both in quantity and quality. Channel Catfish are collected every year in good numbers and are typically in excellent body condition.



The White Crappie is the dominant crappies species in this lake. This population is average but showed promise for good fishing in 2020. 38 White Crappie were collected with 70% of the catchable population exceeding 9”, and 8% exceeding 12”. Average body condition was improved from 2019 (Wr = 93) to 2020 (Wr = 98). 16 White Crappie were collected in 2019. These fish measured 5.9-11.0”. The 2018 survey yielded similar results to 2019, where 15 fish were collected, ranging from 6.5-12.1”. The 2015 fall fish survey showed a catch rate of 33 White Crappie per hour of electrofishing ranging in size from 6.0-12.0”. Only one Black Crappie was collected in 2020, measuring just over 6”. The largest White Crappie ever collected during an electrofishing survey measured over 15” and weighed 1.8 lbs.


Very Good

Historically the Largemouth Bass population has been composed of a low number of individuals in average body condition. The dense Common Carp population was thought to hinder Largemouth Bass feeding and reproduction by creating turbid water and disrupting bass nests during the spawn. In 2015, the catch rate was poor (CPUE = 26). In subsequent years the Largemouth Bass catch rates have improved. Surveys conducted in 2018 (CPUE = 60), 2019 (CPUE = 45), and 2020 (CPUE = 78) yielded improved catch rates. Ideally, 60 or more Largemouth Bass would be sampled in one hour of electrofishing. 34.2% (13 fish) of catchable size fish in the 2019 sample reached 15”. 5.3% (2 fish) exceeded 18”. Body condition was average in 2019 (Wr = 103). In 2020, nearly 38% of the catchable bass population exceeded 15”, and 10% exceeded 18”. Relative Weights remained high in 2020 (Wr = 104).

Location: Southeast edge of Jacksonville. 30 miles west of Springfield just north of I-72.
