� <br />� <br />� <br />� <br />1� <br />� <br />i� <br />The reach of the creek downstream of Mukilteo Boulevard is in a severely degraded <br />condition. Upstream of the boulevard, the stream channel lies mosdy within a narrow, steep <br />ravine. Many barriers to fish migration, including a 10-foot waterfall, restrict (ish passage <br />within this area. <br />PROJECT SITE <br />The project site is located in the Lpper reaches of the drainage, about 2.5 miles from <br />Puget Sound. Approximately 825 feet of stream are contained within the project site. At the <br />upstream end of the site, the creek flows through an open, sparsely vegetated ditch. 7'he <br />channel substrate is primarily large gravel to small cobble lhroughout this reach. The <br />gredient is approximately 3 percent, a somewhat steeper gradient thar. found immediately <br />downstream. Downstream of this reach., the City of Everett has built a regionai detention <br />pond (approximately �.5 acre-feet of storage) sized to liandle flows from the entire drainage. <br />�� FISH USE <br />fA <br />1:9 <br />1�7I <br />ra <br />i• <br />� <br />�' <br />(! <br />� <br />ie <br />ar <br />A number of blockages to fish migration prevents a self-sustaining population of <br />aiwdromous fish from reesWblishing in the stream. Coho salmon fry (age 0+) were captured <br />during sampHng in the lower sections of the creet in 1981, suggesting that limited natural <br />reproducHon may have oautred at that time Furthermore, benthic invertebrate and gravel <br />composiNon sampling results suggest that Merrill and Ring Creek has good incubation <br />habitat qualiry and adequate food resources to supuort a viable fish population in <br />downstrnam reaches. <br />STREAMFLOW AND WATER �UALITY <br />Streamflow and water quality data Eor Merrill anv Ring Creek is limited. One streamflow <br />measurement was made in the lower portion of the �reek in June 1980, at which time the <br />base flow was estimated at 2.5 evbic feet per second (cfs). Within the project site, the creek <br />can be dry for several months during the summer and early fali of each year. To our <br />knowledge, streamflow daW during storm events has not been collected at Merrill and Ring <br />Geek. <br />4 <br />:, f:�t:, q <br />l � .'v+;r <br />, .,: .. <br />, , ? ,., <br />�l 'c�s��'�•, , ' �;''� <br />-- ::'.i, <br />
