Obtaining Stream Stage Data from the USDA / NRCS

Go to the USDA/NRCS National Water & Climate Center water supply site at www.wcc.nrcs.usda.gov/water/w_qnty.html.  If you have trouble with this link, follow the bulletted instructions below:

• Go to the USDA home page at www.usda.gov.
• Choose the Agencies, Services & Programs button near the top.
• Click on the Natural Resources Conservation Service (NRCS) link near the bottom.
• Choose the Technical Resources button at the left.
• Click on the Water and Climate Data link near the bottom.

1. Choose the Water Supply Forecasts link.
2. Click on the Spring & Summer Streamflow Forecast Maps link.
3. For this example, click the Great Basin and California link.

1. Using your browser, backtrack to the Water Supply Forecasts page at www.wcc.nrcs.usda.gov/water/w_qnty.html.
2. Click the Streamflow Forecast Probability Charts link.
3. Choose Utah as the state, Utah Lake, Jordan River & Tooele Valley as the basin, and April 2000 as the month/year.
4. Choose the Submit button.  Several streams, rivers and creeks will be displayed along side bar charts.  These charts show the percent probability that the flowrate will exceed the average by a specified percent (see image below).  For example, there is a 45% chance that PAYSON CK will exceed the average flowrate by 70% (or 4.4 times 1.7).

Data for reservoir storage are also available at this web site.
