Average | A total of 259 Bluegills were collected ranging from 4.4 – 7.6", with 259 > Stock size of 3.1". Average length was 5.5". 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). Body condition fell within the goal range. 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 This is to be expected with the poor Largemouth bass population. | |
Poor | A total of 11 Largemouth Bass were collected ranging from 6.8 – 9.8", with 9 of those fish > Stock size 7.9". Average length was 8.7". The Largemouth bass population has been in a decline since the 2020 fish kill. Previous annual Largemouth bass stockings have been at a rate of <10 advanced fingerling bass per acre. Boosting the annual stocking to 50 advanced fingerling bass per acre will hopefully aid in the recovery of the population. Annual population surveys will be done to assess the recovery of the bass population. | |
Poor | A total of 3 Muskellunge were collected ranging from 578 – 660 mm (22.8 – 26.0 in), with 3 of those fish > Stock size (510 mm [20.1 in]). Average length was 614 mm (24.2 in). The 2023 netting survey yielded no quality and above sized fish for the third year in a row. This adds to the evidence of a total Muskie kill during the 2020 fish kill. | |
Developing | Saugeye were initially stocked in 2022 and will be stocked every year. Future population surveys will be conducted to evaluate stocking success. | |
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.
Lake Sule develops a heavy algae bloom in the summer producing a shallow Secchi depth. The lake drains approximately 700 acres of agricultural land, along with roadside drainage from I-39 and I-88. Major water quality issue and shoreline degradation has developed due to the wave action on this lake.
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.
