Jefferson Project at Lake George Kicks Off Scientific Study of Lake with High-Tech Survey

High Resolution Survey of Lake Bed and Surrounding Mountains to Begin Next Week

BOLTON LANDING, N.Y. -- The Jefferson Project at Lake George is building one of the world's most sophisticated environmental monitoring and prediction systems, which will provide scientists and the community with a real-time picture of the health of the lake. Starting next week, scientists will use a combination of sophisticated aerial and boat-based surveying techniques to create a high-resolution contour map and images of the lakebed and surrounding mountains.

Residents and visitors at Lake George will see a combination of survey boats and aircraft collecting scientific data.
