Abstract
Studies of pollen stratigraphy in conjunction with available information on floodplain sedimentation and rates of channel migration indicate that Hovey Lake is a recent feature, having originated between 600 and 700 years ago. Land-use practices in the region have had a significant effect on rates of sedimentation in the lake. The pre-1830 rate was 0.74 cm/year; the post-1830 rate is 2.45 cm/year. During the history of the lake the regional forests have been constant in composition, while shoreline vegetation has changed appreciably. Cypress became abundant on the lakeshore about 150 years ago.
