Lacamas Creek (Wikipedia) Lacamas Creek is in Clark County, Washington, United States, and flows about 12.5 miles (20.1 km) from headwaters near Camp Bonneville to Lacamas Lake and Round Lake in Camas, and eventually into the Washougal River. Its name is derived from that of the native camas plant. Lacamas Creek is fed by numerous streams, but the five largest tributaries are Matney Creek, Shanghai Creek, Fifth Plain Creek, China Ditch, and Dwyer Creek.
