Dickey-Lincoln School Lakes Project
Construction of the proposed Dickey-Lincoln School Lakes Project in Aroostook County, Maine will result in the isolation of an area of land due to the impoundment behind Dickey Dam. This land area is located between the United States - Canadian border, the Little Black River, the impoundment (elevation = 913 feet), the Big Black River, and the Shields Branch of the Big Black River, and comprises 183,768 acres of land. A previous report (ERT, 1977) determined the forest types within two miles of the impoundment but did not extend to the Canadian border. This report addresses the forest types

Dickey-Lincoln School Lakes Project
Sediment mercury concentrations higher than levels normall y considered trace or background were encountered up to 80 cm belo w the sediment-water interface in samples obtained from four oligotrophi c lakes in northern Maine . These lakes are in three different watershed s and are as far as 65 km apart . The values reported are far lower than levels reported elsewhere from contaminated sites . The distributio n and magnitude of the sediment concentrations encountered suggest long-ter m diffuse mercury inputs to the lakes from the watersheds . In addition , concentrations up to twice as high in near-surface …
