I spent July 11 in Pennacook Cove collecting additional depth data and checking for aquatic plant growth. I covered nearly all of Zone 12 except for the very shallow areas where there were numerous boulders (see map below).
The surface of the water was calm and the visibility was really good so that I could identify plant growth from my pontoon boat. I was also able to grab some samples for a closer look with my grabber. The sonar on my boat was also useful and showed dense plant growth across the area. Aquatic plants included bladderwort, ribbon leaf pondweed, floating bur reed, floating heart, and white water lilies.
