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

Alamo River

The Alamo River is a 52-mile-long stream located in southern California. Historically, it played a significant role in the development of the agricultural industry in the region. The river originates in the Cuyamaca Mountains and flows into the Salton Sea. The hydrology of the river is influenced by the man-made reservoirs and dams built throughout the system. The most notable of these are the Lake Morena Dam, Barrett Dam, and the Lower Otay Dam. These reservoirs provide water for both agricultural and urban uses in the region. The river's flow is also regulated by the United States Bureau of Reclamation. Recreational activities like fishing, hiking, and camping are common along the river, and the area is home to a variety of wildlife species.

FAQ

About the Alamo River

Where does the data for the Alamo 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.
