A Lake Health Update: Untangling The Causes Of Algae Blooms

Summer is algae bloom season in Lake Champlain. We'll talk about lake health, what causes blooms and the state's progress on lake cleanup.

What has this summer looked like so far in terms algae blooms and the health of Lake Champlain? We're getting an update on the latest on the lake: the science of algae blooms and the state of the state's clean-up plan. 

We'll also talk about what triggers algae blooms in the first place. Phosphorus runoff is a part of the story, but the whole picture may be more complicated - with a role for temperature, sediment, and other nutrients like nitrogen. Amid this uncertainty, how can we best address the problem?

We're joined by Mike Winslow, staff scientist at the Lake Champlain Committee.

Listen back to our earlier segment on the possible health effects of blue-green algae.

You can also check out the Health Department's interactive algae tracker map.

Also on the program: what it would it take to make a bicycle the best vehicle to use for a big grocery run? Dave Cohen is founder and director of VBike in Brattleboro, and he'll talk to us about his company and what he calls "rebooting" the bicycle.

And in this installment of Summer School: how to make doughnuts!
