316-acre lake near Grant County. The lake tops out around 12 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 exact depth survey is published on its own because no defensible water-specific species roster was found.
Traced from the shoreline, Alkali Lake runs 316 acres with 3.5 miles of edge. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 1.6 mi of water from one end to the other, 0.5 mi at the beam. You'll find it in Grant County. For a second option, Blue Lake lies 3 mi northeast.
6 pieces of structure are mapped here — Deep basin, around 12 ft, is the deepest of them.
