Fish Status


Very Good

The Bluegill population is doing well. 20% of the catchable sized Bluegill exceeded 7" in the 2018 survey.



20 Channel Catfish were collected in 2016. Catch rate was lower in the 2018 spring sample where only 4 Channel Catfish were collected per hour of electrofishing.


Very Good

The Largemouth Bass numbers have decreased from 2016 to 2018 and since previous surveys, but catch rates are still at or near the goal of 60 fish/hour of electrofishing. The size distribution of the bass collected looks good and fish are present in several year classes. 21% of catchable sized bass exceeded 15" and 14% exceeded 18".

Location: Mt. Olive New City Lake is located in southeastern Macoupin County, 2.7 miles northwest of Mt. Olive, IL. The boat ramp can be accessed from New Reservoir Lane.

Description: The lake has excessive organic sediment, is very fertile, and has had fish kills in the past. The lake has had consistent aquatic plant problems including algae blooms and duckweed.

History and Status of the Sport Fishery: The status of the fishery is good. Largemouth bass numbers and size distribution are good. More bluegill are reaching 7 inches. The fish community in this lake should provide some good sport fishing opportunities.
