104-acre lake near Bon Homme County. The lake tops out around 37 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Henry Lake runs 108 acres with 4.2 miles of edge. The 2.9 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. 70% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 0.9 mi of water from one end to the other, 0.6 mi at the beam. You'll find it in Bon Homme County. Closest neighbour on DepthScout: Beaver Lake, 16 mi southeast of here.
Spring yellow perch on Henry Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
