201-acre lake near Carlton County. The lake tops out around 60 ft. The depth data here comes from the Minnesota DNR survey of 1993 (the DNR's original lake-survey map). Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 201 acres, worked by 5.7 miles of shoreline. With a shoreline index of 2.9, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 42% of this chart. Call it 2 mi long by 0.7 mi wide at the broadest reach. Carlton County claims this one. Its nearest charted neighbour, Forbay, is 2 mi to the west.
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. The spot to know is Secondary point, a point in about 11 ft of water that rates prime for walleye in fall. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
