Glendo Reservoir fishing: Walleye, Largemouth Bass, Sauger
Target species: Walleye, Largemouth Bass, Sauger, Black Crappie
The reservoir
Glendo Reservoir covers 12,059 acres in Wyoming, across 2 counties: Platte and Converse. It is a reservoir: 92% of it is 60 feet deep or less; the deepest point measured is at least 120 feet (36.6 m); at the dam, USGS RESSED gives 145 feet (44.2 m) at full pool. Our records hold 8 species for this water.
Depth and bottom
Deepest measured point: at least 120 ft (36.6 m). That is the deepest contour line: the bottom goes deeper. USGS RESSED gives 145 ft (44.2 m) at the dam at full pool: a measured figure, not a survey map. 92% of the water is 60 feet or shallower. We hold 115 depth contours for this water, drawn from 2,041,399 soundings.

Water and conditions
Our water temperature readings average 70°F; they do not cover the whole year, so this is not a yearly average. pH averages 8.2. These readings span 2017–2018. The latest reading is from 2018, more than three years ago: read these numbers as history, not as the water today.
What is hard here
Wind is the limit, not the fish: 12,059 acres of open water build a short steep chop, and there is no shelter in the middle.
