MN DNR lake survey finder

Find Minnesota lakes within up to 50 miles (wider searches use multiple DNR requests), filter by fish species and max depth, optional public pier/site filters (bundled DNR fishing-sites data), and open official LakeFinder pages for depth maps and surveys.

Radius: 1.0 mi (up to 50 mi)

Each DNR request covers at most about 10 miles. Wider radii use multiple requests from this server, merged and de-duplicated, then filtered to your chosen distance.

Fish species

Matches common names from the static list plus species seen in the current search. Leave empty to show all lakes in the radius.

Minimum max depth (ft): any

Uses DNR max depth (feet). Lakes with unknown depth (often shown as 0 in source data) are hidden when you set a minimum above zero.

Public fishing sites (DNR layer)

Filter by lakes that appear in the bundled "Public Fishing Sites" dataset (piers, shore sites, etc.). Run npm run build:fishing-sites after adding GeoJSON — see data/README.md.
