410-acre lake near Lakewood. The lake tops out around 20 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. Species by species, here's what the data says the year looks like.
On the chart, Steilacoom Lake draws 410 acres inside 3.5 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 83% of the water is 15 ft or less, the band where the food chain lives. Figure 1.5 mi of water from one end to the other, 0.6 mi at the beam. The water lies in Pierce County.
