Fuller and Cooper (1946) provided early information on hydrology. Greene et al (1992) include waterbody-specific details on lake and stream chemistry pre-1990s in Appendix 7-1. Lake specific data can be found at Lakes of Maine, which includes links to data collected by Maine DEP and the Lake Stewards of Maine. The National Water Quality Monitoring Council has an online search tool allowing access to data from USGS, EPA, NPS, and other agencies, including those from many lakes and streams in Acadia National Park.
