18-acre reservoir near Mono County. The lake tops out around 15 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. What the data behind the map says about each species, season by season:
On the chart, Junction Reservoir draws 17 acres inside 0.8 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. End to end it runs roughly 0.3 mi, about 0.2 mi across. You'll find it in Mono County. The nearest mapped water is Poore Lake, 3 mi to the southwest.
Spring puts rainbow trout in skinny water — 4 to 15 ft is the zone. Summer fish stay in 4 to 15 ft, and winter fish hold in 3 to 15 ft. Winter rainbow trout concentrate at Shoreline break, a prime-rated drop-off around 7 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
