96-acre lake near Pierce County. The lake tops out around 50 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Harts Lake runs 96 acres with 1.4 miles of edge. At index 1 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 19% of the surface — that's where the groceries are. Call it 0.5 mi long by 0.4 mi wide at the broadest reach. The water lies in Pierce County. For a second option, Elbow Lake lies 4 mi south.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 32 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
