If you've spent time in or around Lake Champlain lately, chances are you've seen the blue-green algae turning the water thick and green and uninviting. After all the flooding last year, which sent record amounts of phosphorous into the lake, and a recent streak of hot weather, the blue-green algae blooms have appeared earlier than normal this year, and have been more widespread. They've also been cropping up in Lake Memphremagog and Lake Iroquois. We talk to Louis Porter, Lake Champlain Lakekeeper at the Conservation Law Foundation, and Mary Watzin, dean of the Rubenstein School of Environment and Natural Resources at UVM, and a long-term researcher on Lake Champlain, about the health of the lake, and what the blue-green algae blooms mean for the surrounding environment, animals and humans.

Also on the program, Olympic mountain biker Lea Davison. The Jericho resident will represent the United States in London at the Olympic Games. As Davidson prepares to leave for Europe, we talk to her about the training, the competition and the honor of being an Olympian.

And, a collection of twenty curious wooden boxes have made appearances in a handful Vermont state parks this summer. Each box is a speaker with a small solar panel mounted on top. Together, they create a meditative and tranquil sound installation called Sun Boxes. Musician and artist Craig Colorusso created Sun Boxes and has been installing them in public spaces around the country.
