Rex River

Chester Morse Lake (originally Cedar Lake) is a lake in the upper region of the Cedar River watershed in the U.S. state of Washington. The original lake surface was 1,530 feet (466 m) above sea level, but when the river was dammed in 1900, the elevation was raised to 1,560 feet (475 m). Chester Morse Lake is more than four miles (6 km) long, and is primarily fed from the east by the north and south forks of the Cedar River, and from the south by the Rex River. The lake is part of the Seattle area water supply. Located in the upper watershed, Chester Morse Lake is impounded by the masonry dam and a secondary control structure called the Overflow Dike. The lake now functions as a water supply storage reservoir and powers a 30-megawatt hydroelectric facility. Chester Morse Lake was previously a natural lake called Cedar Lake. Cedar Lake was formed about 14,000 years ago by the terminal moraine of an alpine glacier descending the Cedar River valley from the upper elevations of the Cascade Mountains. Because upstream fish passage to Chester Morse Lake is naturally blocked by Cedar Falls, the fish populations in the lake are isolated from those downstream. Bull trout and pygmy whitefish populations in Chester Morse Lake have thus been separated from other populations for at least 13,000 years, and represent unique genetic stocks of these species. Both of these species spend most of their time in deeper portions of the lake. The surface of Chester Morse Lake has an average annual fluctuation of about 20 feet in elevation. Inundation of the Cedar and Rex river deltas strongly affects their aquatic and wetland habitats. Changes in lake level management toward higher lake levels in the past 15 years have resulted in a retreat upslope of sedge and willow communities on the delta. Inundation of the Cedar and Rex river channels within and upstream of the delta causes sedimentation that can negatively affect bull trout eggs. Studies are underway to examine these effects.

Mount Washington is a small mountain in the US state of Washington roughly 30 miles (48 km) east-southeast of Seattle, Washington along Interstate 90. It lies on the western margin of the Cascade Range just above the coastal plains around Puget Sound, and is southeast of nearby town of North Bend. Once known as Profile Mountain, Mount Washington was named due to a cliff resembling a profile of George Washington when viewed from an angle.The hike to the top of Mt. Washington is known for its view. Cedar Butte lies at the west end of the mountain.

Olallie State Park is a public recreation area featuring multiple waterfalls located five miles (8.0 km) southeast of North Bend, Washington. The state park spans a 3.5-mile (5.6 km) stretch along the South Fork of the Snoqualmie River. The most prominent feature of the park is 135-foot-high (41 m) Twin Falls.

Cedar Butte a small forested mountain south of North Bend, Washington. It is east of Rattlesnake Lake at the foot of Mount Washington. The summit can be reached by a low-impact hike from the Iron Horse Trail.

Weeks Falls is a waterfall on the south fork of the Snoqualmie River, located near North Bend, Washington, USA, just south of Interstate 90 at exit 38. The falls are at the end of the road that goes past the Olallie State Park ranger headquarters. From the gravel parking lot, there is a paved accessible overlook to see the falls and a small area around the hydro-electric plant. There is also a ¼ mile accessible interpretive trail nearby.Weeks Falls has a small hydroelectric plant operated by CHI West which generates about 4.3 Megawatts peak. It is unusual because it operates without a dam. Instead, water is being drawn from the river above the falls and run down an underground channel to the generation unit at the bottom of Weeks Falls.

Edgewick is an unincorporated community in King County, in the U.S. state of Washington.

McClellan Butte is a prominent peak in the Cascade Range in King County, Washington 11 miles east of North Bend. The McClellan Butte hiking trail is a difficult trail known as an alternative to Mount Si's crowded trail.

Mount Kent is a 5,087-foot (1,551-metre) mountain summit located in east King County of Washington state. It's part of the Cascade Range and is situated on land managed by Mount Baker-Snoqualmie National Forest. Precipitation runoff on the mountain drains north into Alice Creek, a tributary of the South Fork Snoqualmie River. The nearest higher neighbor is McClellan Butte, 1.16 mi (1.87 km) to the north, and Mount Defiance is set 4 mi (6.4 km) to the northeast across the Interstate 90 corridor.

The Washington State Fire Training Academy is a firefighting training center near North Bend, Washington, United States. It is operated by the Washington State Patrol and includes classrooms, dormitories, and several simulation centers. The facility opened in 1984.

Cedar Falls is an unincorporated community in King County, Washington. It began as a construction camp for the Seattle Municipal Light and Power Plant. It was a joint-company town of Seattle City Light, Seattle Water Department, and Chicago, Milwaukee, St. Paul and Pacific Railroad, with each company providing separate housing and amenities for its employees and their families.

Rattlesnake Lake is a lake in the northwest United States, located in Rattlesnake Mountain Scenic Area in King County, Washington, approximately thirty miles (50 km) east of Seattle, south of Interstate 90.

Seattle Municipal Light and Power Plant, also known as Cedar Falls Historic District, is a public hydroelectric plant near North Bend, Washington operated by Seattle City Light. The plant was the first publicly-owned electrical generating plant for Seattle and one of the earliest in the country for a municipality of its size. It was listed on the National Register of Historic Places in 1997.The population of Seattle grew rapidly from 3500 in 1880 to 237,000 in 1910, and the city needed to provide power to its population. Electricity was first used for street lights, and then for electric railways. Ultimately, private customers were provided electricity for lighting and appliances. The Seattle Municipal Light and Power Plant's initial capacity of 3500 kilowatts was increased to 13,500 kilowatts by 1910, and further improvements brought capacity to 40,000 kilowatts. Residents of the city paid one of the country's lowest electrical rates per kilowatt hour, more than half the rate charged by the private firm Seattle Electric Company (renamed Puget Sound Power and Light).
