Integrated Regional Water Management Planning in Napa County

Water in Napa County supports diverse ecology, thriving agriculture, and picturesque open spaces. It also supports a wide variety of communities, commerce, employment and career opportunities. With more than 130,000 water-users and over two dozen agencies overseeing water resources, a focused Integrated Regional Water Management Plan (IRWMP) is helpful to ensure that the community and its ecology continue to flourish by sharing and managing water responsibly and strategically.

By integrating water management plans and related projects, Napa County will ensure that everyone has a say in how we efficiently steward water resources. Management plans are being developed regionally in accordance to major watersheds established by the state, and will work to meet urban, agricultural, industrial, and ecological needs for water resources. 

All water-users and stakeholders are invited to become involved in the IRWMP process. For detailed information on what IRWM is or how to participate please follow the links below or in the side-bar links under Related Content Links.
