Water Quality
The Maine Department of Environmental Protection (ME-DEP) and the Volunteer Lake Monitoring Program (VLMP) have collaborated in the collection of lake data to evaluate water quality, track algal blooms, and determine water quality trends. This information does not include data for bacteria, mercury, toxics or nutrients other than phosphorus. Phosphorus is considered the primary limiting nutrient for algal growth in Maine lakes.

Water quality monitoring data sets for Crescent Lake have been collected since 1974. During this period, 12 years of basic chemical information was collected in addition to Secchi Disk Transparencies (SDT). In summary, the water quality of Crescent Lake is considered above average based on measures of SDT, total phosphorus (TP), and Chlorophyll-a (Chla). The potential for nuisance algal blooms on Crescent Lake is moderate.

Transparency
​Secchi Disk measurements of water transparency (how clear the water is). This simple test can characterize lake water quality and identify changes over time. Click Here.
Dissolved Oxygen & Temperature
​An adequate supply of dissolved oxygen (DO) in lake water is essential to fish and other aquatic life forms. DO is a sensitive indicator of lake water quality. Click Here.
