Murray 1949 Triturus rivularis Sept 3 4 mi N Willow Creek, 600 ft., Humboldt Co., Calif. Found one in a pool about 10 x 4 feet and 8" deep. This was in the bed of Horse Linto Creek, not far from where it drained into the Trinity River. Became quite broad, and this was near the edge where water evidently flowed in the Winter. Now had dried to a few pools. Slightly brackish, the Triturus was resting on the bottom.
