Juniata River Flow
As of 2026-08-03, the Juniata River is flowing at a combined 10,660 cfs across 4 USGS streamgauges — 200% of normal for this time of year, versus a seasonal average of 5,319 cfs.
Total streamflow across the Juniata River was last observed at 10,660 cfs, and is expected to yield approximately 21,144 acre-ft of water today; about 200% of normal. River levels are high. Average streamflow for this time of year is 5,319 cfs, with recent peaks last observed on 2024-04-04 when daily discharge volume was observed at 171,300 cfs.
Maximum discharge along the river is currently at the Juniata River At Mapleton Depot reporting a streamflow rate of 3,170 cfs. However, the streamgauge with the highest stage along the river is the Juniata River At Lewistown with a gauge stage of 5.35 ft. This river is monitored from 4 different streamgauging stations along the Juniata River, the highest being situated at an altitude of 602 ft, the Juniata River At Huntingdon.

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.

Juniata River
The Juniata River is a 104-mile-long tributary of the Susquehanna River, located in central Pennsylvania. The river has played a significant role in the region's history, serving as a transportation route for Native Americans and early settlers. The river's hydrology has been altered by several dams, including Raystown Lake, which was created in 1973 by the construction of the Raystown Dam. The lake is a popular destination for boating, fishing, and camping. The river and its tributaries also provide water for agriculture and industry, supporting the region's economy. However, the river has faced challenges such as pollution, sedimentation, and damming, requiring ongoing efforts to protect its health and biodiversity. Despite these challenges, the Juniata River remains an important natural and cultural resource in central Pennsylvania.

About the Juniata River
How is the Juniata River flowing right now?
As of 2026-08-03, the Juniata River is flowing at a combined 10,660 cfs across its USGS streamgauges, about 200% of normal for this date. The live per-gauge breakdown and 24-hour trend are shown above.
Is the Juniata River running high or low right now?
Check the percent-of-normal figure on this page: above 100% means the river is running higher than its seasonal average for the date, below 100% means lower. The per-gauge table shows which reaches are highest and lowest.
Where does the data for the Juniata 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.
