East Smith Lake reaches 38 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. East Smith Lake covers 152 acres alongside 5.0 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Among the 141 graded lakes in Itasca County, East Smith Lake sits at rank 62, above the county median.
No invasive species are currently listed at East Smith Lake — the lake remains off the Minnesota infested-waters roster. The fishery is bass-led, with 5 documented species across the lake's records.
