Grand Marais area fisheries announces survey work

Grand MaraisFisheries staff from the Minnesota DNR Grand Marais area office will conduct surveys and assessments on several Cook County lakes and streams during the next few months. Fisheries surveys are performed on a regular basis to monitor changes in fish populations and to determine if management strategies have been effective. Survey methods and frequencies vary based on the types of information needed for ongoing management evaluations in individual lakes and streams. 

Large lakes and trout streams with heavy use are surveyed more frequently than small, remote lakes and streams. Stocked lakes are also sampled more often to better assess stocking success. Most lakes are surveyed using gill nets and trap nets, while most streams are surveyed using backpack electrofishing gear.

Fisheries surveys are largely funded by license fee dollars and are subject to change. The number of lakes and streams scheduled for survey in 2017 has been substantially reduced due to an anticipated funding shortage. Lakes and streams may be added or dropped, and the timing and duration of some surveys may change.

Information about area lakes and streams can be addressed to the DNR’s Grand Marais area fisheries office by calling (218) 387-6021 or email

Preliminary results for many of the 2017 surveys should be available in the fall of 2017. Final reports will be completed by the spring of 2018. Final lake survey results will be available online at or from the Grand Marais area fisheries office.
