The San Juan River is a major tributary of the Colorado River and its flow is provided by snowmelt and precipitation from the San Juan Mountains. The river is regulated by Navajo Dam, which was built in the 1960s. Seasonally, the river experiences high flows during the spring runoff and lower flows during the summer months. The hydrology of the San Juan River is influenced by local geology, including the presence of limestone formations that can influence water chemistry. Additionally, the San Juan River is famous for its recreational opportunities, including world-class fly fishing and white-water rafting.
