A small patch of CLP was recently discovered in North Pond, and the “serpentine” stream connecting to East Pond. It has also been documented in Legion Pond, West Pond, and the Kennebec River. In the photos below you can see the wavy nature of the leaves. There are many native pondweeds in Maine, so it is good to get photos if you see anything that looks like this.
