1722: 1565: 1253: 513: 699:, recorded an average annual discharge of 2,152 cubic feet per second (60.9 m/s), or 1,559,000 acre-feet (1.923 km), for the 1915–2013 period. Before the construction of major dams to regulate the river, it sometimes dried up completely in the summer, as it did in 1934 and 1939. The maximum flow was 70,000 cubic feet per second (2,000 m/s) on September 10, 1927. The great flood of October 1911, which remains the largest recorded flood on the San Juan River, occurred before the USGS began measuring streamflow here. Based on observations of water depth and debris deposits, the 1911 flood may have reached a peak of 148,000 cubic feet per second (4,200 m/s). 1986:

water-skiing, fishing, and shoreline camping; two marinas are located in the New Mexico portion of the lake. The 6 miles (9.7 km) of river from below Navajo Dam to Gobernador Wash are known as one of the best trout fishing waters in the United States due to the cold, clear flows released from the base of the dam. Cutthroat, rainbow and brown trout are present in this section of the San Juan River. Although trout are present in another 13 miles (21 km) further downstream to Cañon Largo, the fishery is diminished in quality due to rising amounts of sediment. These "Quality Waters" of the San Juan River are visited by well over 50,000 anglers each year.

1945:, creating off-channel spawning habitat. Since the completion of the Navajo Dam, the portion of the San Juan River between the dam and Farmington became unsuitable for native fish due to the reduction in seasonal fluctuations. However, at Farmington the San Juan is joined by the Animas River – which is not controlled by any major dams – and regains some of its seasonal characteristics. In addition, the impoundment of water at Navajo Dam does not appear to have a significant effect on the amount of sediment transported in the river; thus, the aquatic environment of the lower San Juan, though somewhat degraded, still resembles pre-development conditions. 525: 1994:, about 20 miles (32 km) down the river, although some continue through the lower canyons to Clay Hills, near the head of Lake Powell, 56 miles (90 km) further downstream.

Applications for private trips are approved by the Bureau of Land Management's Monticello Field Office via lottery; about 900 spots are awarded each year out of more than 4000 requests.

operations and to generate hydroelectricity (an early hydro project was the Tacoma power station, built on the Animas River in 1905.) In 1901, the Turley survey concluded that the San Juan River contained enough water to irrigate up to 1,300,000 acres (530,000 ha), but due to the high cost of delivering water to desert lands, neither private investors nor the federal government were willing to fund such large projects. The U.S. Reclamation Service (now the Bureau of Reclamation) conducted surveys of dam sites on the lower San Juan River in 1914, as part of the

The lowest elevation, where the San Juan River flows into Lake Powell, has a normal maximum elevation of 3,704 feet (1,129 m) but typically fluctuates dozens of feet per year due to seasonal nature of runoff in the Colorado River Basin affecting the reservoir level. Most of the watershed is rural, with some extremely remote, uninhabited areas. About 75 percent of the watershed is shrubland, rangeland, and grassland. Due to the low rainfall and lack of substantial 504:, one of the largest reservoirs in the United States. Efficient management is crucial to ensuring enough water supply not just for farms and urban areas but also for recreational boating, fisheries, and environmental restoration. However, heavy water use has significantly reduced the flow of the San Juan River by as much as 25 percent since pre-development conditions. In addition, warming temperatures in the Rocky Mountains are projected to have a further negative effect on snowpack and thus stream flow. 1106:

the river, from about 2,600 cu ft/s (74 m/s) in the 1914–1963 period to less than 2,000 cubic feet per second (57 m/s) for the 1964–2016 period, although a minimum release from the dam prevents the river from drying up in the summer. Persistent drought conditions in the 21st century have further reduced the flow of the San Juan River, with an average annual discharge of 1,358 cubic feet per second (38.5 m/s) or 984,000 acre-feet (1.214 km) between water years 2000 and 2016.

1473:. Most settlements were concentrated along the upper San Juan River in New Mexico, where the terrain is gentler and water more abundant. The lower San Juan River in Utah flows through inaccessible canyons that largely precluded habitation. Starting around 1300 AD, a warming climate brought long droughts to the area, forcing the Puebloans to abandon their settlements north of the San Juan River and perhaps eventually causing them to migrate out of the San Juan River basin to the 1628:. However, the Navajo were allowed to return to much of their original lands in 1868, and a federally recognized reservation was established south of the San Juan River. The Utes, who had been granted a reservation in western Colorado in 1868, faced hostility with settlers because most of the area's mineral wealth was concentrated on Ute lands. The U.S. Army drove the last of the Utes from southwest Colorado by 1881 (with the exception of a small portion in the 53: 65: 5034: 5028: 5016: 1793:(the so-called "Bluff reservoir" was never built, after engineers determined that the high silt load of the lower San Juan would make a storage reservoir here useless within a short time). By the 1920s – with the oil boom spurring rapid growth in the Farmington area and food shortages impacting the Navajo Nation – the federal government recognized the need for a multi-purpose dam project on the upper San Juan River, which would later become 5022: 1971: 1808:, whose aim was to regulate the water supply of the upper Colorado River system, control floods and generate power. Navajo Dam, completed in 1963 after five years of construction, impounds 1.7 million acre feet (2.1 km) of water in Navajo Lake. The dam serves for flood control, irrigation and long-term water storage, and its operations are paired with two major water projects of the upper San Juan River: the 1781: 5010: 2500: 2451: 2426: 1650:(1908) that a federally established Indian reservation was "entitled to the water needed to create a permanent homeland."
