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.

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 Duck Fork Reservoir: what the data says

51-acre reservoir in Sanpete County, Utah. The lake tops out around 21 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. Below is the species-by-species picture, pulled from the same data the map uses.

The drawn water covers 39 acres wrapped in 1 miles of bank. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. About 58% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 0.3 mi long by 0.3 mi wide at the broadest reach. Sanpete County claims this one. If the bite dies, Ferron Reservoir is 2 mi to the south.

Cutthroat Trout fishing at Duck Fork Reservoir

Start shallow in spring: cutthroat trout sit in 3 to 15 ft that time of year. Summer pushes them deeper, 6 to 21 ft, and winter fish settle into 5 to 21 ft. The spot to know is Shoreline break, a drop-off in about 9 ft of water that rates prime for cutthroat trout in summer. Warm-month bites cluster around early morning and the evening. Throw a trolled spoon (small) or an inline spinner until the fish tell you otherwise.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 15 ft	dawn & dusk	Shoreline break (9 ft)	Inline spinner (silver/gold), Small spoon
Summer	6 to 21 ft	dawn & dusk	Shoreline break (9 ft)	Trolled spoon (small), Inline spinner
Fall	4 to 21 ft	dawn & dusk	Shoreline break (9 ft)	Casting spoon, Inline spinner
Winter	5 to 21 ft	dawn	Shoreline break (9 ft)	Small jigging spoon, Marabou jig
