Description The Washington State Department of Ecology conducted a survey on the Pend Oreille River to compare fish communities from a naturally weeded (non-rotovated) and trail- rotovated habitat. Differences could not be determined due to low numbers of fish. Water quality data from non-rotovated, trail-rotovated, totally rotovated and open water habitats were compared. Conductivity was higher and total P lower at totally rotovated and open water habitats versus non-rotovated and trail-rotovated habitats. Surface total P was significantly lower at the non-rotovated habitat. Plant biomass and taxonomic identification were determined from macrophyte samples. Potamogeton zosteriformis, Myriophyllum spicatum, and Elodea canadenis dominated the plant community. Recommendations for further work are included.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
