Water <br />quality was determined to be similar to 1969 <br />data, and zinc was the most abundant toxic <br />metal found. High levels of lead, zinc, and <br />copper were found in aquatic insects. Data <br />were also presented on accumulation differentials <br />by insect order for various metals. Waters <br />studied were Willow Creek, Rio Grande River, <br />and Animas River (Creede area); Henson Creek <br />and Lake Fork of the Gunnison River (Lake City <br />area); Animas River and Cunningham Gulch (Silver- <br />ton area); and Ten Mile Creek and North Fort <br />Ten Mile Creek (Climax area). <br />156.
