663-acre lake near Renville County. The lake tops out around 10 ft. The depth data here comes from the Minnesota DNR survey of 1979, a decades-old survey (the DNR's original lake-survey map). Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Preston runs 663 acres with 4.8 miles of edge. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. End to end it runs roughly 1.7 mi, about 1 mi across. The water lies in Renville County. Closest neighbour on DepthScout: Allie, 2 mi northwest of here.
Come spring, look for walleye tight to the bank in 3 to 10 ft. Through summer count on 3 to 10 ft; the winter hold is 3 to 10 ft.
