Rangeley’s diverse hydrology and high concentration of lakes, ponds, rivers, streams, and wetlands make this region truly unique. These waters are among our most valuable and treasured assets. They form the foundation of the region’s rich heritage while providing unparalleled recreational, scenic, and economic opportunities for residents and visitors. Protecting them from non-source pollution, algae blooms, and invasive aquatic plants is critical to their welfare and our economy.

RLHT’s Headwaters Coordinator, Sadie Gray, spent the summer of 2024 studying the health of our lakes and ponds. She collected water samples at stations around each lake to compile data on key lake health metrics including water temperature, transparency, dissolved oxygen, and chemistry data including phosphorus readings. 

Collecting and observing this data not only helps us understand the current trends occurring on our local lakes but also observe long-term trends that could be changing due to climate change, shorter winters, increased development, and runoff.
