East River river
Total streamflow across the East River was last observed at 404 cfs, and is expected to yield approximately 801 acre-ft of water today; about 37% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 1,093 cfs, with recent peaks last observed on 2019-06-15 when daily discharge volume was observed at 5,780 cfs.
Maximum discharge along the river is currently at the East River Bl Cement Creek Nr Crested Butte reporting a streamflow rate of 404 cfs. However, the streamgauge with the highest stage along the river is the East River At Ct Highway Zz Near Greenleaf with a gauge stage of 4.98 ft. This river is monitored from 3 different streamgauging stations along the East River, the highest being situated at an altitude of 8,444 ft, the East River Bl Cement Creek Nr Crested Butte.

Maximum streamflow discharge by year
The single highest aggregate discharge recorded each year. Spotting the multi-year trend reveals droughts vs. wet cycles long before the headline daily flow does.

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.

East River
The East River is a tidal strait that flows between the boroughs of Manhattan and the Bronx in New York City. It is approximately 16 miles long and is one of the five boroughs' waterways. Historically, the East River was a busy and important shipping channel and played a significant role in the city's growth and development. Today, it serves as a critical source of water for the city, with numerous reservoirs and dams along its course. These include the Kensico Reservoir, which stores water from the Catskill Mountains, and the Ashokan Reservoir, which provides water to the city's residents. The river also offers a range of recreational activities, including fishing, boating, and kayaking. Agricultural use along the East River is limited due to its urban location.

Set per-gauge push alerts (e.g. "alert me when flow at the Russian R Nr Healdsburg crosses 5,000 cfs"), and Snoflo's iOS app pushes the moment USGS reports the crossing.
About the East River
Where does the data for the East 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.
