Pulls fish to the windward grassy banks and edges for months — fish the bank the wind blows ONTO.

The friendliest crossover of the summer: on lakes, drift the windward bank with a bubble-and-foam-hopper — the bubble's splash doesn't hurt a hopper presentation. On rivers, the same rig dead-drifted along the undercut grass banks, or small gold spinners under the banks between rises.

The event happens over grassy banks, undercut edges and windward shorelines

Recommendations come from depth structure and seasonal species behavior. Treat them as a starting point, not a guarantee. Contours on this water are approximations. Never use for navigation. Always check local regulations.

Fishing Nine Mile Reservoir: what the data says

124-acre reservoir in Sanpete County, Utah. The lake tops out around 36 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. What the data behind the map says about each species, season by season:

Nine Mile Reservoir's chart carries 2.4 miles of bank. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. About 54% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 1 mi end to end and 0.5 mi across at its widest. It sits in Sanpete County. If the bite dies, Palisade Reservoir is 3 mi to the northeast.

Rainbow Trout fishing at Nine Mile Reservoir

Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 7 to 36 ft. Put Break off the point first on the milk run — a drop-off near 16 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.

Season	Depth	Best window	Start at	Go-to baits
Spring	5 to 20 ft	dawn & dusk	Main-lake point (9 ft)	Inline spinner (silver), Small spoon
Summer	8 to 30 ft	dawn & dusk	Break off the point (16 ft)	Dodger + spoon (deep troll), Flutter spoon
Fall	10 to 35 ft	dawn & dusk	Main-lake point (9 ft)	Casting spoon, Jerkbait over shoals
Winter	7 to 36 ft	dawn	Break off the point (16 ft)	Jigging spoon, Tube jig (white)
