From XMS Wiki - http://wikis.aquaveo.com/xms/
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.
- Choose the Water Supply Forecasts link.
- Click on the Spring & Summer Streamflow Forecast Maps link.
- For this example, click the Great Basin and California link.
- Choose the April 2000 button. The image should look similar to the one below.
- Using your browser, backtrack to the Water Supply Forecasts page at www.wcc.nrcs.usda.gov/water/w_qnty.html.
- Click the Streamflow Forecast Probability Charts link.
- Choose Utah as the state, Utah Lake, Jordan River & Tooele Valley as the basin, and April 2000 as the month/year.
- 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.
