Abstract. Smallmouth bass Micropterus dolomieui
congregate in the headwaters of Lake Moomaw, a 1024-ha flood-control reservoir, during
the spring spawning period, where they are vulnerable to a shore-based, harvest-oriented
fishery. We estimated the headwaters bass harvest in 1995-96 by creel survey, then used
tagging and telemetry to assess the significance of the harvest to the whole-lake bass
population. Electrofishing surveys of juvenile bass distribution were conducted to examine
impacts on recruitment. The headwaters fishery accounted for 17% of the annual smallmouth
bass harvest in lake Moomaw; the combined annual harvest removed only 12% of the adult
population. Bass spawning occurred throughout the lake. The headwaters fishery is a
high-profile activity which, during 1995-96, had a low and sustainable impact on the Lake
Moomaw smallmouth bass population.
