Combined Downstream Route <br />(Downstream Map 1) <br />From the point where they converge (Photo 10), the two downstream paths continue East <br />as a stream named Silver Lake Creek (Photo 11 and 12). Silver Lake Creek has been <br />established as a type 3 stream by previous projects. Previous downstream analyses note a <br />36 inch culvert a few hundred feet downstream of the Herschlip development, but this <br />culvert was not located during site visits for this project. Beyond the mile downstream <br />point the creek enters Ruggs Lake. A stream, now called Penny Creek, flows southeast <br />from Ruggs Lake and continues southeast, then south, as it passes through a number of <br />roadway culverts, as well as Thomas Lake, before eventually entering the Sammamish <br />River. <br />Photo 10.
