BLUEGILL

Poor

A total of 351 Bluegills were collected ranging from 20 – 182 mm (0.8 – 7.2 in), with 223 > Stock size (80 mm [3.1 in]). This survey did meet the minimum required number of fish > Stock size (n = 50) to quantify population demographics as set forth in the Lake Management Plan (LMP). The PSD fell within its respective target ranges, albeit on the lower end while RSD-7 fish were not collected. Body condition (as indexed by relative weight) exceeded the 90th percentile for Quality and Preferred sized fish. A high body condition indicates sufficient forage for fish growth. Despite Bluegill densities being high, and good Bluegill body condition, very few larger Bluegill were collected (as indicated by low the RSD-7 value). It’s possible that larger fish are present but were difficult to collect due to water clarity and water levels being low at the time of the survey.

LARGEMOUTH BASS

Fair

A total of 95 Largemouth Bass were collected ranging from 95 – 385 mm (3.7 – 15.2 in), with 50 of those fish > Stock size (200 mm [7.9 in]). This survey met the minimum required number of fish > Stock size (n = 40) to accurately quantify population demographics as set forth in the Lake Management Plan (LMP). Both the PSD and RSD-14 fell below their respective target ranges. A lower PSD and RSD-14 value could indicate a growth bottleneck due to an overabundance of Stock and Quality-sized Largemouth Bass which limits forage availability and/or overabundant vegetation making foraging difficult. This may be due to the Largemouth bass stocking program that was started a couple years ago. Also, larger sized bass could have been missed due to the water level being very low during sampling.

MUSKELLUNGE

Improving

The Muskie population at Lake Sule has been historically good but no Muskie where collected in the 2021 trap net survey. Muskie were also observed in the August 2020 fish kill which could have reduced the population. If no Muskie are collected in the 2022 trap net survey a second trap net survey will be conducted.

Location: Lake Sule is located at the junction of I39 and I88 southeast of Rochelle in Ogle County Illinois.

Description: The lake has a maximum depth of 15 feet with an average depth of 8.5 feet. The lake is nearly rectangular in shape with a shoreline of 1.4 miles and no bays or indentations. With 76.6 acres the lake contains 653.7-acre feet of water or nearly 213 million gallons.

History and Status of the Sport Fishery: Lake Sule is a dug borrow pit whose fill was used for overpass construction of I-39 and the junction of I-88 southeast of Rochelle. Digging commenced in 1979 and the lake was formed in January 1982 after digging had stopped in the fall of 1981. An incoming ditch drains the interstate highway and agricultural land to the east. The outflow forms a major eastern tributary of the Kyte Creek system. Through the efforts of Mike Sule and Lyle Kundy the Flagg-Rochelle Park District was deeded this property in 1982 as a future fishing lake and recreational area. In 1991 a boating grant was awarded to the park district for development of facilities and a boat launch. By 1994 a boat launch and an access road were in place. In October 1996 the lake was dedicated as Lake Sule in the Lyle Kundy recreational area in a well-attended outdoor ceremony.
