Alpine County, Carson City, Churchill County, Douglas County and Lyon County are in the Carson River Watershed.  Each county has the potential to impact the downstream communities making flooding a watershed-wide challenge.

A Regional Floodplain Management Plan was developed in 2008 to create a similar vision and mechanism to achieve goals related to floodplain management. The five counties within the Carson River Watershed adopted it and are implementing within their communities.  The Plan was most recently updated in 2018.
