64-acre reservoir near Humboldt County. The lake tops out around 18 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. The rest of this page walks each species through its year, using the map's own scoring.
Onion Valley Reservoir maps at 82 acres behind 1.8 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. The shallow band under 15 ft claims about 88% of the surface on the model — that's where the groceries are. The basin spans about 0.7 mi end to end and 0.3 mi across at its widest. Humboldt County claims this one. Its nearest charted neighbour, Catnip Reservoir, is 40 mi to the northwest.
Spring rainbow trout on Onion Valley Reservoir hold shallow, usually 5 to 18 ft. Depth-wise the year is flat: 5 to 18 ft in summer, 4 to 18 ft once it turns cold. Put Creek inflow first on the milk run — an inflow / creek mouth near 4 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
