The Puyallup River is a 45-mile long river located in Pierce County, Washington. The river is known for its rich history as it was once home to the Puyallup Tribe who relied on the river for fishing and trade. Today, the river is used for recreational activities such as fishing, boating, and hiking. The river's hydrology is heavily influenced by Mount Rainier and its surrounding glaciers, causing the river to have high flows during the spring and low flows during the summer. Spanaway Lake and Lake Tapps are two reservoirs along the river that are used for hydroelectric power generation, irrigation, and flood control. The river is also important for agriculture as it provides irrigation to several farms in the area. However, the river faces challenges with water pollution and habitat degradation, leading to efforts to improve water quality and restore salmon populations.
