Numerous studies indicate relative consistency in major Holocene lake-level changes in the Midwest. However, a survey of lake-level studies from sites across New England, the Mid-Atlantic states, and neighboring Canada shows significant variability in both timing and direction of water-balance changes. Using the methods refined by Almquist, et al., in their study of Mansell Pond, Central Maine, we are developing Holocene lake-level curves for three lakes in Maine. These studies, along with the Mansell Pond study, will provide a comprehensive picture of lake-level changes across the northern and eastern portions of the state. Preliminary results indicate that the magnitude and trend of water-balance changes are consistent across the region. However, the timing of these fluctuations is asynchronous.
