DNR fish survey, 2015

Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.

Lost Lake is a small, mesotrophic lake located approximately 12 miles southeast of Bigfork, Minnesota. It is 88 acres in size, of which 46 acres (53%) is less than 15 feet in depth. The maximum depth is 28 feet and the shoreline length is 1.9 miles. A public access and a State Forest Campground are located on the south shore The lake is relatively clear and supports a diverse aquatic plant community. The Secchi disk reading, a standard measure of water clarity, was was 8.0 feet in 2015, and has ranged from 9.0 - 19.0 feet in previous surveys. Lost Lake is in lake class 29. Other Grand Rapids Area lakes in this class include Beauty and Deadhorse. The 2004 Lake Management Plan (LMP) lists Walleye, Black Crappie and Bluegill as primary species for management and Northern Pike and Largemouth Bass as secondary species. The LMP goals were to achieve a Walleye catch of 2.0/gill net, achieve a Black Crappie catch of 6.0/trap net and maintain a Bluegill catch of 16.0/trap net. A standard survey was conducted in June of 2015 to assess the status and characteristics of the fish community using three gill nets and nine trap nets. An electrofishing survey in late April evaluated the Largemouth Bass population. Northern Pike were the most common fish captured in gill nets. The catch rate of 10.7/gill net was within the expected range for similar lakes. Northern Pike gill net catches have been above this range in all previous surveys. Size structure of pike improved slightly from the 1989 and 2003 surveys, but remained relatively poor as only 31% of the sample exceeded 21 inches in length. Northern Pike from gill nets ranged in length from 11.7-33.4 inches, with an average length of 21.7 inches. Seven consecutive age classes (1-7) were sampled with 80% being age 2-4. Growth was near the statewide average with an average length of 21.1 inches at age-4. The Walleye catch increased from 1.0/gill net in 2003 to 1.7/gill net, but remains within the expected range. Walleye natural reproduction appears to be sustaining a low level population. Walleye fingerlings were stocked in 2006, 2008 and 2010. Of the five Walleye sampled in 2015, only one corresponded to a stocked year class. In the 2003 assessment, no Walleye sampled were from stocked years. Walleye ranged in length from 20.1-21.6 inches, with an average length of 20.9 inches. The LMP goal of 2.0/gill net was not met. Bluegill were captured at a rate of 25.0 /trap net, which is within the expected range. Bluegill trap net catches have ranged from 16.2-32.8/net in previous surveys. Eight consecutive year classes were…
