Lake Aeration Project

Lake Carmi had the distinction of being the first lake in Vermont designated as “lake in crisis,” following a year of back-to-back blooms of cyanobacteria that have blanketed the lake’s waters with a thick, green and potentially toxic, scum. A “perfect storm of factors” had led to a particularly bad year for the 1,375-acre lake, the response plan said. Heavy rainfall early in the year resulted in runoff that was laden with nutrients. And then an unusual cold spell in August caused the water in the lake to turn over earlier than normal — a phenomenon normally associated with autumn, when air temperatures drop, and the cooled surface water sinks — releasing phosphorus from deep in the lake. The lake water turned over again in October, leading to blooms through November. The toxic blooms forced the closure of beaches and a local state park for weeks, due to public health concerns. Camp owners, residents and environmental advocates converged on the Statehouse during the recent session, demanding action. Read the complete story. |
