• Where to Fish on G G Upper Reservoir

  We hold no survey for this water; read the slope of the shoreline instead. The old creek line under the surface is the feature worth finding. Standing timber shows when the level drops, and fish sit against it. County-wide records name brook trout, brown trout, rainbow trout, cutthroat trout and black-spotted cutthroat trout. Read it as a county summary, not a water-by-water list. The shape of G G Upper Reservoir decides where the fish sit.

• Seasonal Patterns

  The warm month here averages 58°F; the cold one sits at 17°F. Seasons are distinct, and each one fishes differently. Look for the thaw near early May; the fishing lifts straight after. Going by climate averages, expect open water from about early May until roughly mid November. Spring is short and heavy here; autumn is longer and steadier. Plan any trip to G G Upper Reservoir around it.

• Tackle & Baits

  The rules here are undocumented as far as public sources go. Nothing formal is recorded here: no ramp, no car park, no marked path. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Bank access can be seasonal on ground like this. Some ground is open by custom rather than by right, so tread carefully. Schlegel Lake at 1.6 miles is the sensible second choice. Treat access at G G Upper Reservoir as something to verify.
