Lake Bottom Blanket



The lake bottom barrier is ideal for managing out-of-control aquatic vegetation. This barrier is constructed of professional-grade filter fabric and is placed near swimming areas, by docks, or in other places where aquatic plants become troublesome for boaters or swimmers.

A geotextile lake bottom blanket is typically cut into 12’ x 12’ sections or less and is then framed so that it will lay flat. The barrier will need to be anchored or weighted down to the lakebed to ensure it doesn’t move or itself become an obstacle to boats or swimmers. By blocking the sunlight from getting through to the vegetation beneath this barrier helps to stop plant growth.

This barrier can be constructed and installed by a homeowner. The ideal time to place install a lake bottom barrier is during the winter when much of the aquatic plants have died back for the season. By waiting until winter or early spring you can reduce the work needed with installation. Should you have to install this during the summer or peak vegetation growth then it’s advisable to prune and cut back the aquatic plants before placing the barrier down.

As the plants degrade gas bubbles will rise to the surface and lift the fabric. It’s good to monitor this 1-2 times a month to be sure that the frame hasn’t lifted. If excessive gas persists, then it’s advisable to make a few slits in the fabric to help alleviate the gas build-up.
