The Missisquoi River basin is one of the most polluted sections in Lake Champlain, consistently failing to meet pollution limits. Now, a Franklin County project is developing new detailed forest maps to identify roads that might be contributing to phosphorus runoff. The conservation group Cold Hollow to Canada is teaming up with researchers from the University of Vermont to find previously unmapped roads in forest lands. They're using LIDAR data, which is gathered by flying over land, shooting down laser beams and recording their bounce-back reflections to get a detailed measure of the land features below.

Sediment-laden water flows down the Winooski River. There's no simple fix for keeping pollution out of the lake, in part due to the state's vast network of waterways, hilly landscape and unique geography.Why It's So Tough To Keep Nutrient Pollution Out Of Lake Champlain
