The Puyallup watershed (HUC 17110014) covers an area of approximately 1,196 square miles in western Washington. The watershed is fed by snowpack in the winter and rain in the other months. The Puyallup River is the main water source for the watershed, and it is important for fish habitat and recreational activities. The watershed also contains several reservoirs, including Alder Lake and Lake Tapps, which provide water for municipal and industrial use. The climate in the Puyallup watershed is characterized by mild, wet winters and cool, dry summers. The area receives an average of 50 inches of precipitation per year. Interesting climatic trends in the area include an increase in extreme precipitation events, which have the potential to cause flooding and landslides, and a decrease in snowpack, which can impact water availability in the summer. Overall, the Puyallup watershed is an important natural resource for the region, and efforts are underway to protect and restore its ecological health.
