Every five years, the Lake Champlain Basin Program issues a report on
the environmental indicators of Lake Champlain. The 2012 State of the
Lake report shows that phosphorous and invasive aquatic species are
still the leading threats to the lake ecosystem.
A comprehensive report on the
health of Lake Champlain says there’s still too much phosphorus pollution in
the big lake. The report does note some
good news, such as declining mercury concentrations in fish.
After last year’s flooding, which sent record amounts of
phosphorous into the lake, and a recent streak of hot weather, blue-green
algae blooms have appeared in Lake Champlain earlier than normal this year, and have been more
Missisquoi Bay has been plagued for years by
some of the worst phosphorus pollution and blue-green algae in Lake Champlain. Phosphorus comes primarily from agricultural
runoff. So the U.S. Agriculture Department wants to pay farmers to adopt
practices that would keep pollution from running off their fields and into the

Champlain was still rising,
inundating homes, roads, fields and businesses. For more than two
months, the lake was above flood stage. The impact, on residents in communities
all along the lake, and on the environment was significant.
