1,500-acre reservoir near Hereford. The lake tops out around 129 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Below is the species-by-species picture, pulled from the same data the map uses.
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 20 to 45 ft. If you only fish one area, make it Main-lake point: a point around 27 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.

|---|---|---|---|

In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 15 to 35 ft. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for largemouth bass in spring. In summer the feeding windows fall in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
