Alamosa River

Total streamflow across the Alamosa River was last observed at 110 cfs, and is expected to yield approximately 218 acre-ft of water today; about 25% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 435 cfs, with recent peaks last observed on 2017-06-06 when daily discharge volume was observed at 2,373 cfs.

Maximum discharge along the river is currently at the Alamosa River Above Terrace Reservoir reporting a streamflow rate of 110.00 cfs. However, the streamgauge with the highest stage along the river is the Alamosa River Below Terrace Reservoir with a gauge stage of 2.83 ft. This river is monitored from 3 different streamgauging stations along the Alamosa River, the highest being situated at an altitude of 9,403 ft, the Alamosa River Above Wightman Fork Near Jasper.

It stretches 50 miles from its headwaters in the San Juan Mountains to its confluence with the Rio Grande. Historically, the river was used for gold mining and agriculture, but today, it is primarily used for recreation, including fishing and kayaking. The river's hydrology is heavily influenced by snowmelt, which can cause significant flooding during the spring and early summer. There are several reservoirs and dams on the Alamosa River, including Terrace Reservoir and Platoro Reservoir. These reservoirs were built for irrigation purposes and to manage the river's flow for flood control. Despite the use of the river for recreation and agriculture, efforts are being made to improve water quality and habitat for fish and wildlife.
