The final snowpack report of the year for Wyoming was released Tuesday by the Natural Resources Conservation Service. The report indicates that for the 2011 water year, the Tongue River Basin is at 137% of normal for May 1st, and 247% of the May 1, 2010 totals. The Clear Creek Basin shows similar numbers at the higher elevation sites, with the low elevation snow courses still with measurable snow and also well above last year's report. Total precipitation at the snotel sites since October 1, 2010 on both the Tongue and Clear Creek Basins is about 115% of normal.
The report also indicated that due to these numbers, the NRCS is issuing a high water run-ff notification for much of the state. NRCS Water Supply Specialist Lee Hackleman said that due to cool temps and high snow packs, there is a lot of water that will be coming down the mountains and into the rivers in the near future and that they wanted to alert people around the state about these high volumes.
The final snowpack report also showed that snotel readings on the other major basins around the state are all in excess of 100%. Daily data from these sites, as well as other water supply-related reports can be accessed by clicking here.
