The Interstate Council on Water Policy (ICWP) is announcing that over the next 24 months, it will engage over 100 partners—including State water-management agencies, interstate basin commissions, and NGOs—in (1) communicating the importance of water data and science in informing water resources policy and planning; and (2) identifying and promoting opportunities to enhance State and regional water-resource planning efforts. As part of this effort, ICWP will convene at least two national stakeholder workshops focused on waterdata collection and water use, and at least two workshops highlighting successful practices from State and interstate water-plan development.
