24-acre lake near Snohomish County. The lake tops out around 40 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. Here is how the season plays out for each species, straight from the data behind the map.
Riley Lake maps at 24 acres behind 0.9 miles of shoreline. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 40% of the water is 15 ft or less, the band where the food chain lives. Figure 0.4 mi of water from one end to the other. Snohomish County claims this one. If the bite dies, Lake Cavanaugh is 6 mi to the northwest.
