Thornton Creek water quality presentation Jan 23

A very large section of Shoreline, from about 190th southwards, around the Shoreline Center, is in the Thornton Creek Watershed. We are the farthest north section of the watershed.

According to King County, "The North Branch drains approximately 4,446 acres of Shoreline and Seattle. The South Branch originates west of I-5 near the North Seattle Community College and drains approximately 2,333 acres of Seattle. The creek and its tributaries flow over 15 miles and drain approximately 7,402 acres before entering the northern end of Lake Washington at Matthews Beach Park."
