Technical Advisory Committee
The TAC initiates projects that are of interest and beneficial to the water stakeholders participating in the CPWP. Examples of projects include the development and updating of the water supply and demand maps for the region, grant applications, groundwater computer modeling, coordination of funding for stream flow gages and identification/planning for the annual stakeholder field trips.
The Coconino Plateau Watershed Partnership (CPWP) Technical Advisory Committee (TAC) consists of volunteers that meet monthly either virtually or in person prior to the CPWP meetings. Meetings of the TAC are open to anyone with interest in the hydrology/geology of the area of interest.
