Facts

• The Santa Fe River Watershed is 285 square miles – from Lake Peak (12,408’) in the Sangre de Cristo Mountains to the confluence with the Rio Grande at Cochiti (5,220’).
• 10% of this area (17,400 acres) lies above the City of Santa Fe, primarily within the Santa Fe National Forest.
• At Lake Peak, precipitation averages 35 inches/year; at Santa Fe 14 inches/year; at Cochiti 10 inches/year.
• The Santa Fe River is 46 miles long.
• The reach from Santa Fe Lake to Nichols Dam is roughly 10 miles.
• The Santa Fe River was first dammed in 1881. The Old Stone Dam filled with silt during a flash flood in the fall of 1904. It is now within the 188-acre Santa Fe Canyon Preserve, managed by The Nature Conservancy and open to the public (but not to dogs).
• An acre foot of water covers one acre (43,560 square feet) with water one foot deep. This equals 326,000 gallons.
• In 2003, the City of Santa Fe used 12,000 acre feet of water – 59% from wells and 41% from the river. In 2006, we used 9,300 acre feet – 78% from wells and 22% from the river. In 2007, we used 9,200 acre feet – 51% from wells and 49% from the river.
• In 1995, the City’s per capita water consumption was 168 gallons. In 2006, we used 37% less (106 per person)!
• 1,000 acre feet equates to a flow of about 1.5 cubic feet/second (cfs), or ten gallons/second, 365 days/year.
• The stream gauge below McClure Reservoir has recorded annual flows as exceptionally high as 19,000 acre feet (in 1919) and as low as 1,530 (1950).
