Lake Gilmer is located roughly 15 miles north of Longview and four miles west of Gilmer in Upsher County. The lake is 1,010 surface acres, with an average maximum depth of 28 feet. Aquatic vegetation on the lake is low density. Natural habitat exists in the form of inundated timber and brush and some aquatic vegetation.
The largemouth bass population at Gilmer Reservoir can be described as one of moderate numbers with good condition and growth characteristics. Relative abundance of legal-size bass is low, but good numbers of fish are available for catch and release. Channel catfish are present and fishing opportunities are good. Growth of channel cats is excellent and good numbers are available for harvest. Although the relative abundance of crappie species is good, very few legal-size fish are available. The fishery should improve over the next several years as crappie grow to legal size. Several species of sunfish are present, including bluegill, redear sunfish, and warmouth. Bluegill dominates with good numbers of fish over 6 inches available for harvest. Most species are managed under statewide regulations with one exception. The largemouth bass is an exception with 18-inch minimum length and a daily bag limit of five fish.
