GRAND ISLE, Vt. — Efforts to manage the quality of Lake Champlain are going well, but the lake continues to face many challenges in light of global climate change and other factors.
The Lake Champlain Basin Program released an updated version of its State of the Lake report Wednesday with dignitaries praising the collaborative effort in producing the study while cautioning that the job is far from completed.
“This is our best effort (to produce) a complete description of the current state of the lake, our best effort to summarize those points,” said Bill Howland, program manager for the Basin Program.
“The biggest question we hear is, ‘Is the lake getting better or worse?’” he added. “That is a hard question to answer. This (report) is our best effort to answer the question.”
The report was released during a meeting at Gorden Center House on Grand Isle in Vermont, just north of the Grand Isle Ferry Dock.
The Basin Program utilized technical reports and statistics from dozens of scientists, researchers and government agencies from both sides of the lake and Canada, Howland noted.
The report looks at how human activities exert pressure on the lake, how the ecosystem is impacted by that pressure and what management responses are used to reduce negative impacts on the lake.
It also uses a color-coded scorecard to identify strengths and challenges throughout the five distinct regions of Lake Champlain.
“Each lake segment has its own story to tell,” Howland said. “Most of Lake Champlain is in very good overall condition.”
The section identified as the “main lake” contains 81 percent of the lake’s water, and although phosphorus levels there are above acceptable goals, other environmental indicators for that section continue to hold their own.
Mississquoi Bay, located in the northeast corner of the lake and split by the Vermont/Canada border, is an area of special interest because it is a shallow, warm body of water and receives a lot of agricultural runoff, which is a prime contributor of phosphorus, a nutrient that promotes algae and other plant growth in the lake.
