Invasive and Noxious Lake and Shore Weeds
Yellow Flag Iris. Pretty yellow flowers, but a stubborn invasive weed that can take over.
Pull when young or carefully dig out mature plants minimizing shore disturbance. Make sure to get the whole rhizome and destroy seed pods! Always replace with native plants (or Reed Canarygrass will move in like a bad neighbor).
Native Shore Species to Encourage and Plant
These plants look great, are easy to care for, protect the shore from toxic run off and erosion and provide vital habitat to birds and frogs.

Properly remove Curlyleaf Pondweed
The professional herbicide treatments done in our lake can only do so much. Manual removal will significantly boost the effectiveness of the annual chemical treatments:
Get a weed rake. Make sure it PULLS weeds and roots out and doesn't just cut them. Remove the weeds from the lake, leaving them will make the problem worse. "Weed razor" rakes are not suitable.
