Total streamflow across the Purgatoire River was last observed at 81 cfs, and is expected to yield approximately 161 acre-ft of water today; about 12% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 691 cfs, with recent peaks last observed on 2017-05-13 when daily discharge volume was observed at 11,568 cfs.

Maximum discharge along the river is currently at the Purgatoire River At Trinidad reporting a streamflow rate of 34.70 cfs. However, the streamgauge with the highest stage along the river is the Purgatoire River At Rock Crossing Nr Timpas with a gauge stage of 5.5 ft. This river is monitored from 7 different streamgauging stations along the Purgatoire River, the highest being situated at an altitude of 6,265 ft, the Purgatoire River At Madrid.

Profile

Streamflow elevation profile

Each bubble is one gauge along the river, plotted by current streamflow (x-axis) vs elevation (y-axis), sized by gauge stage. Reading top-to-bottom traces the river from headwaters down to its mouth -- you can see flow accumulate as elevation drops.

About this river

Purgatoire River

The Purgatoire River, also known as the Purgatory River, is a 200-mile-long tributary of the Arkansas River in southern Colorado and western Kansas. The river has a rich history dating back to the ancient Puebloan people who lived in the area. The river is known for its unique geology and hydrology, including the famous Picketwire Canyonlands, where dinosaur tracks can be seen. The river's flow is regulated by several reservoirs and dams, including the Purgatoire River Diversion Dam and the Valdez Reservoir. The river is used for agricultural purposes, including irrigation, and is a popular destination for recreational activities such as fishing, kayaking, and camping. The Purgatoire River is an important natural resource in the region, providing water for wildlife and people alike.

FAQ

About the Purgatoire River

Where does the data for the Purgatoire River come from?

Streamflow and gauge stage data are sourced from the U.S. Geological Survey (USGS) National Water Information System. The aggregate flow shown at the top of the page is computed by Snoflo as the sum of all monitored gauges along the river.

How is "percent of normal" calculated?

Today's aggregate streamflow is compared to the historical average aggregate streamflow on this calendar day across the river's full record. 100% means right on average; values above 100% indicate above-normal flow (wet year); values below indicate below-normal (dry year or drought).

Why are some gauges showing very different flows?

Gauges along a river measure flow at different points: headwater gauges read what's coming off the snowpack or mountain runoff; downstream gauges integrate everything upstream, including tributary inputs. Wide spreads usually mean a tributary is contributing significantly between gauges.

What's the elevation profile chart showing?

Each bubble is one gauge along the river, plotted by streamflow (x-axis) and elevation (y-axis), sized by gauge stage. Reading top-down traces the river from headwaters to mouth -- you can see flow build as elevation drops.

Can I get alerts when a specific gauge crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app on a per-gauge basis. Open any individual streamgauge from the table above and favorite it to set a discharge threshold.
