Bottom Screens

Northwest Aquatic Management offers bottom screening in the early spring and fall. This particular treatment can be very useful in areas where there is little boat traffic and little drifting vegetation and controls most aquatic plants.

A bottom screen or benthic barrier covers the sediment like a blanket, compressing aquatic plants while reducing or blocking light.

In addition to controlling nuisance weeds around docks and in swimming beaches, bottom screening has become an important tool to help eradicate and contain early infestations of noxious weeds.
