Commentsdense in much of the lake; Cloudy, light breeze, started raining. Water level about 3 ft low. Egeria seemed very dense, perhaps due to the low water. South of the launch it was nearly a monoculture to the point where the lake narrows. The north part of the lake was a little more diverse, with P. amplifolius being the next most common species visible from the surface.
