This web page displays  interactive  state-wide content which allows the water user to directly interact with the maps and products created by the NRCS and other cooperating agencies. 

***While useful for assessing periods between the official monthly reports, these tools should only be used to supplement the monthly products. Since they use a smaller selection of sites to create daily products, they offer a reasonable, but not comprehensive, overview of overall snowpack and precipitation.  

This web page allows water users in individual river basins to see interactive maps, plots and other information specific to their river basin, or sub-basin of interest. 

Click on the link to visit be directed to an example river basin, or use the Navigation Bar at the top view your river basin of interest.
