Lake weeds

sunset on the dock · 08-22-2009, 01:39 PM

Does anybody know anything about these lake weeds? They seem to grow in sandy areas and send a stalk up to the surface. Underwater, they are large mats of short green leaves. I was trying to look up these weeds to see if they were invasive but didn't have any luck. There seem to be more of them than in years past and in the areas where we swim I've been able to easily weed them out by diving down and pulling them up with my hands. Is this short to medium term effective? It looks real nice where I've "weeded"...all white and sandy and nice to walk on again. Anyone know the name of this aquatic plant?

Could it be this (millfoil)?

Nope...definitely not millfoil which I'm familiar with. This weed has a long, slender stalk (about the diameter of a cocktail straw but several feet long) and it comes to the surface and often an inch or 2 above the surface. At the tip is a little button like ending, about the size of a small nail head. The base of the plant, with roots in the sand, is never more than a few inches above the bottom of the lake.

I think it's called pipewort. Some years it seems much more prolific than others.

I have referred to this website often when in question of what is growing around our dock, and have found it quite useful!
