186-acre lake near Itasca County. The lake tops out around 7 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 187 acres wrapped in 2.8 miles of bank. A middling shoreline index (1.5) gives it some bays to work without being a maze. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Figure 1 mi of water from one end to the other, 0.5 mi at the beam. Itasca County claims this one. Smith sits 2 mi southwest — the closest neighbouring chart.
Spring brown bullhead on Carlson hold shallow, usually 2 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 2 to 7 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 6 ft that grades prime for winter. The feeding windows run after dark and the evening.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
