743-acre lake near St. Louis County. The lake tops out around 15 ft. The depth data here comes from the Minnesota DNR survey of 1971, a decades-old survey (the DNR's original lake-survey map). Below is the species-by-species picture, pulled from the same data the map uses.
Oriniack maps at 743 acres behind 10.8 miles of shoreline. An index of 2.8 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. They don't go far with the seasons — 5 to 15 ft covers summer, 5 to 15 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 10 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Break off the point (10 ft) | 1/8 oz jig + minnow, Hair jig |
