Interactive Map Links - Nevada and Eastern Sierra

 

 

 

The Interactive Map “Conditions” interface displays current and historical conditions for snow water equivalent, snow depth, snow density, precipitation, reservoir storage, streamflow volumes, and forecasted streamflow volumes collected by the Natural Resources Conservation Service and other monitoring agencies.

The Interactive Map has many custom data analysis capabilities using different duration periods. The data in the map can be exported as a .csv file to a spreadsheet using the option in the left sidebar menu. For more information about how to use the tool go to the Interactive Map Help Center.

Use the “Give us feedback” button in the top right of the Interactive Map if you have comments or suggestions for the developers.

Below are a links to pre-defined reports specifically optimized for Nevada and the Sierra Nevada:
