The Rex River is a river located in the state of Washington in the United States. It starts high up in the Cascade Range mountains. The river flows mostly northwest. It eventually joins the Cedar River. This happens in the Chester Morse Lake reservoir.
The Cedar River then flows into Lake Washington. From there, its waters ultimately reach Puget Sound. Smaller streams that flow into the Rex River are called tributaries. These include Pine Creek, Lindsay Creek, and Boulder Creek.
River's Journey
The Rex River begins its journey in the beautiful Cascade Range. This is a large mountain range. Its source is at coordinates 47°18′7″N 121°36′9″W / 47.30194°N 121.60250°W. The river then travels through the landscape. It flows until it reaches its mouth. The mouth of the Rex River is where it meets the Cedar River. This meeting point is in Chester Morse Lake. The coordinates for the mouth are 47°22′43″N 121°41′48″W / 47.37861°N 121.69667°W.
The area of land that drains into the Rex River is called its basin. The Rex River basin covers about 13.4 sq mi (35 km2). This shows how much land contributes water to the river.
Water for the City
The entire Rex River is found within a special area. This area is called the Cedar River Municipal Watershed. A watershed is a land area that channels rainfall and snowmelt to creeks, streams, and rivers. This specific watershed is managed by the City of Seattle. It plays a very important role.
The water from this watershed helps supply two-thirds of the drinking water. This water goes to the large Seattle metropolitan region. This means the Rex River, even though it's small, helps provide clean water for many people.
