152-acre lake near Mammoth Lakes. The lake tops out around 290 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 150 acres, worked by 2.4 miles of shoreline. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. 2% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 1 mi, about 0.4 mi across. If the bite dies, Edith Lake is 1 mi to the northwest.
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one.

Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
