Submitted December 8, 1947. 13 pp., 1 tbl., 6 figures (5 photos). Ahstract: The two lower Twin Lakes over a period of years had become obstructed by dense aquatic plant growth, chiefly A7iacharis. The main portion of the center lake ( acres) and the lower lake ( acres) were each treated with 700 pounds of sodium arsenlte, with 75 percent arsenious oxide, mixed with water and applied as spray. Effective initial concentration for the center lake was and for the lower lake. Collapse of plant growth reopened the entire acres treated in the center lake nearly a month after treatment; and by onset of winter freezeover two and one-half weeks after treatment in the lower lake, of the entire acres had been reopened by similar collapse. Fish loss was negligible. Since sodium arsenite will not control or eliminate aquatic vegetation permanently, periodic treatment of the Twin Lakes, important for angling and recreation, may be necessary.
