6,389-acre lake near Osakis. The lake tops out around 60 ft. The depth data here comes from the Minnesota DNR survey of 1964, a decades-old survey (the DNR's original lake-survey map). Species by species, here's what the data says the year looks like.
The outline encloses 6,296 acres, worked by 29.2 miles of shoreline, broken up by 61 islands. With a shoreline index of 2.6, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 52% of the surface — that's where the groceries are. The basin spans about 7.4 mi end to end and 2.7 mi across at its widest. Todd County claims this one. If the bite dies, Faille is 3 mi to the south.
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 30 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Rock reef (6 ft) | 1/8 oz jig + minnow, Hair jig |
