The U.S. Fish and Wildlife Service says a warning has been lifted against using the water of southern Lake Champlain. That follows the application of chemicals to kill sea lamprey in two Vermont rivers.

Officials once feared that a long-sunken tugboat at the bottom of a Lake Champlain could be a looming environmental disaster.

Divers are braving the dark depths of Lake Champlain to see if there's still fuel on a tugboat that sank in 1963.

This is the time of year when toxic blue-green algae problems begin to crop up in Lake Champlain. Now, a new program has been launched to reduce the phosphorous that feeds the algae when it washes into the lake in stormwater runoff.

A special state loan program designed to help businesses that have suffered flood damages this spring will be made available across Vermont.

A lingering snow pack and warm heavy rains have contributed to  flood conditions, but the impact of all this water is also related to how we develop and use land adjacent to rivers and lakes.

The spring floods that have torn up roadways and damaged lakefront property are having an environmental impact as well. The high water has washed phosphorus and other pollutants downstream into Lake Champlain, and climate change could make the problem worse.

Many roads in northern Vermont are closed today because they're underwater or washed out from spring snowmelt and rainfall. State police and Vermont Emergency Management say a number of roads along the western slopes of the Green Mountains and in the Northeast Kingdom are affected.

Scientists and a corps of volunteers are launching an all-out assault on a tiny invasive clam in hopes of preventing it from befouling the crystal-clear waters Lake George.

The Burlington Public Works department says the Vermont city's sewage treatment plant is operating normally again after about 250,000 gallons of raw sewage was inadvertently released into Lake Champlain.

When a Burlington wastewater plant released 2.5 million gallons of stormwater and untreated sewage into Lake Champlain this week, it was not an isolated incident. A state database shows that sewage spills are relatively common throughout the Lake Champlain basin.

The Burlington Department of Public Works says operator error caused about 2.5 million gallons of untreated sewage and stormwater to flow into Lake Champlain.

The Vermont House has swept aside concerns about ‘government over-reaching' to advance a bill that would restrict fertilizer use on lawns.

Lawmakers want to help Lake Champlain by limiting the use of fertilizer spread on home lawns, because the phosphorus used to grow green grass can also feed the toxic algae in the big lake.

Last month, the EPA rejected Vermont's 9-year-old plan for reducing phosphorous pollution in the lake, saying it doesn't meet federal regulations.

The federal Environmental Protection Agency has rejected Vermont's cleanup plan for Lake Champlain.  The agency says Vermont has made progress, but needs to do more to cut phosphorus pollution in the big lake.

The U.S. Environmental Protection Agency wants a diver to explore a sunken tugboat in Lake Champlain that could contain thousands of gallons of fuel oil.

The new year may bring a new, comprehensive clean up plan for Lake Champlain. The current plan was finalized eight years ago. But the regional head of the Environmental Protection Agency says it should be updated because conditions affecting the lake have changed.

Almost 15 years ago, Vermont, New York and the EPA signed an agreement to address water quality in Lake Champlain. The latest version of the plan is scheduled to be signed this week.

Burlington Mayor Bob Kiss discusses the future of Burlington Telecom, the city-owned utility that broke its equipment lease this month due to inability to make payments.

VPR's Jane Lindholm talks with and aquatic ecologist, the Director of Science and Stewardship for the Vermont chapter of The Nature Conservancy and the director of the Clean & Clear program about climate change's effect on Lake Champlain.

A new study from The Nature Conservancy examines specific effects of climate change on the Lake Champlain basin, based on an array of climate models and historical data. We learn more about the research and the findings. Also, a program at UVM helps farms prepare for and manage outbreaks of animal illness, like foot-and-mouth disease.

A new study says Lake Champlain's levels are higher because of increased precipitation. And researchers say the wetter weather may cause more phosphorus pollution to wash off the land and harm the big lake.

The City of Rutland is grappling with a crisis in its Police Department, stemming from a child pornography investigation focused on an officer. We talk with Mayor Chris Louras about how the police investigation is being handled, and other critical issues facing Rutland. And reporter Candace Page explains why the EPA is looking at Vermont's Lake Champlain Cleanup goals.

The Environmental Protection Agency is reconsidering its approval of a state clean up plan for Lake Champlain. The plan was approved by the federal government in 2002, but pollution levels have continued to rise in the big lake.
