Mill Creek is a tributary to Dry Creek, west of the City of Healdsburg in the Russian River watershed. Other major tributaries within this sub-basin include Felta, Wallace, and Palmer creeks. The watershed is primarily hardwood, chaparral, and conifer forest with land use being mainly timber, rural residential, and vineyards. The post-European settlement practice of heavily logging forests, has left a legacy on the landscape. Poorly constructed roads used for logging and unsustainable logging practices have had detrimental effects on the hydrology of the watershed that can be seen to this day.  Currently, landholdings within Mill Creek are primarily privately owned and no incorporated cities, towns, or public lands reside within the watershed. Although the land use within this watershed is diverse, the area is known as an award winning wine region. Sonoma RCD works with private landowners to improve the landscape of the watershed by road improvement, habitat enhancement, and projects that benefit streamflow and water security for all water users alike.
