Freshwater DataStream

Station 17B050 Description

Chimacum Creek flows north out of two glacially carved lowland valleys in northeastern Jefferson County to the southern end of Port Townsend Bay, at Irondale. The East Fork and West Fork, together with small tributaries, comprise 29.5 miles of stream that converge into the mainstem at RM 2.7. The area of the watershed is approximately 37 square miles. The East and West forks represent one-third and two-thirds, respectively, of the total flow. The East Fork starts in the flat-bottomed Chimacum Valley, approximately four and one-half miles upstream from the confluence point at an elevation of 180 ft. The West Fork is longer, reaching into the uplands southeast of Discovery Bay.
