History & Status of the Fishery
Little Rock Lake (DOW# 05-0013-00; Lake Class 41) is a 1,310-acre lake located near Rice, Minnesota. A Minnesota Department of Natural Resources (MNDNR) owned concrete boat ramp is located on the south Shore west of Highway 10. Little Rock Lake has 10.58 miles of shoreline and a maximum depth of 17 feet. Little Rock Lake is in Lake Class 41. Lakes in this class are generally very large, shallow, have a very high amount of water less than 15 feet deep, have very hard water, high turbidity, and are an irregular shape. Primary management species on Little Rock Lake include Walleye and Black Crappie, Secondary management species includes Northern Pike.
Although Walleye stockings may have occurred prior to accurate record keeping, historical records show Walleye stocking beginning on Little Rock Lake in 1945 and ending in 1990. Stocking consisted primarily of fingerling and yearling Walleye. Due to the documentation of natural reproduction in 1991, stocking was discontinued to observe whether population management goals could be met through natural reproduction. No stocking has been needed since stocking was terminated.
Fall electrofishing has been utilized annually to assess natural reproduction of Walleye on Little Rock Lake. Sampling in 2023 was conducted on September 6, and effort totaled 1.0 hour of electrofishing on-time. A total of 40 young of the year Walleye were captured during the assessment for a catch rate of 40.0/hour which was above the median (30.0/hour). Catch rates from previous fall electrofishing surveys have ranged from 3.6/hour in 2008 to 147.1/hour in 2013. Young of the year Walleye sampled in 2023 ranged from 4.5 to 8.9 inches and averaged 7.1 inches, which was larger than the average (6.0 inches) calculated since 1997. Sampling conditions in 2023 were challenging with heavy algae blooms present which made it difficult to see fish, a condition not uncommon during fall assessments. Catch rates were probably negatively impacted due to poor visibility and would probably have been higher with clearer water conditions. Moderate fall young of the year Walleye catch rates have produced good future year classes in the past on Little Rock Lake. The catch rate (40.0/hour) of juvenile Walleye observed in 2023 suggests a good year class was produced and should contribute to good angling opportunities in a few years.
Other species commonly observed during the assessment included: Bigmouth Buffalo, Black Crappie, Bluegill, Common Carp, Largemouth Bass, Smallmouth Bass, Spottail Shiner, Trout-perch, White Sucker, and Yellow Perch. Additional information can be found on the DNR website (www.dnr.state.mn.us) or by contacting the Little Falls Area Fisheries office.
