I post a daily report on the status of western rivers on downriverequip.com. The report tabulates and graphs the relationship of the two most recent weeks of snowpack, temperature and riverflow. This information allows a baseline of knowledge to readily permit future runoff predictions by even the most casual observer.
That aside, the report has bookmarks/hyperlinks to over a thousand web pages of greatest interest to western river runners.
Symbols 0 through 6(columns 32 to 38(identified at the bottom of the table on page 1)) link to significant government web pages detailing past flows and future predictions of flow for selected rivers. In fact, the report evolves daily as new information becomes available or sources of information are discovered.
Symbol 0 (by tomorrow) will be Beau's Snow to Flow chart defining the continuity of snow pack to run off plotted on a time line. The chart allows for the interactive comparison of our current year vs past years.
Symbol 1 is a link to a NOAA short range flow prediction.
Symbol 2 is a link to a NOAA long term assessment of flow probability.
Symbol 3 is a link to the Colorado Basin River Forecast Center similar to Symbol 1 but for a slightly longer prediction.
Symbol 4 is a raster hydrograph that allows a comparison of current status to the life of a gaging station going back in some case over 100 years.
Symbol 5 is a listing of the daily average flows for the life of the gaging station.
Symbol 6 is reserved for the "RFC"(River Forecast Center) graph mentioned by Wadeinthewater.
The nature of the hyperlinks/bookmarks presented in the report attempts to permit instant access to all of the available sources of information to allow an interested river runner to understand and predict future flows(as best as possible).
