Fishing Mountain Lake: what the data says
220-acre reservoir near Oklahoma. The lake tops out around 40 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. Here is how the season plays out for each species, straight from the data behind the map.
Crappie fishing at Mountain Lake
In spring, crappie run shallow here, mostly 2 to 8 ft. They move out to 10 to 25 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Deep basin: a deep basin around 40 ft that scores prime in winter. Best bite is early morning and the evening.
