NWRFC Water Supply Forecast
Monthly
Briefing
-
-
Water is vital resource that affects many aspects of our lives, the
health of our environment and the nation's economy. We use water
directly in our households and industries, or indirectly through the
products and services that we use, like irrigated crops,
hydroelectric power, and river transportation. In addition to our
needs sufficient water is needed to sustain a healthy aquatic
ecosystem. As the population of the Pacific Northwest continues to
grow water resources are becoming more fully utilized, making the
region more vulnerable to water shortages during periods of
abnormally dry weather. On the other end of the spectrum an
excessively large snow pack can cause flooding during the spring
melt. Forecasts of the amount of water expected to runoff from a
basin provide resource managers and water users time to adjust their
operations to better fit the expected runoff.

The NWRFC produces water supply forecasts for much of the Pacific
Northwest and has received increasing interest in these products. To
better meet the needs of our users, the NWRFC is conducting monthly
water supply briefings during this water year. The briefings will
present web pages that display current basin precipitation, snow and
runoff conditions, as well as the latest climatological outlooks and
water supply forecasts. There will be time available for questions
following the presentation.
Water supply briefings are held on the working day immediately
following the release of the monthly “Final” forecast. Please
refer to the schedule
for forecast release dates. The briefings are composed of two parts,
a telephone conference call and a web-based presentation. The
conference call can be accessed by dialing 1-888-324-8131 a few
minutes prior to the 10:00 am start of the briefing and entering the
access code of 61279. To view the web-based presentation, you will
need to sign up prior to the briefing. You will need to re-register
for each meeting. Click on REGISTER

the web-based presentation on your computer, you can follow the
