Yazoo Mississippi Delta Joint Water Management District

This Water Management Plan for the Yazoo Mississippi Delta Joint Water Management District addresses critical water resource challenges. The plan focuses on two major issues: balancing water supplies with demand, specifically by mitigating alluvial aquifer declines and restoring stream base flows, and improving and protecting surface water quality by reducing non-point source pollution. Key objectives include reducing groundwater withdrawals through conservation and surface water development, establishing procedures for defining and restoring base flows, promoting voluntary conservation practices, and integrating stormwater management into broader watershed plans. The approach involves collecting data, constructing projects, maintaining an effective permit process, collaborating with stakeholders, and educating water users.

The plan outlines strategies for water resource management in the Mississippi Delta, focusing on conservation, tailwater recovery, and on-farm storage. Its primary goal is to improve water use efficiency and halt the 100,000 acre-feet per year aquifer overdraft, while also enhancing water quality. Key initiatives include developing a collaborative network among farmers and agencies, establishing a GIS for regional resource data, creating a framework for coordinated practice implementation, and planning the installation of tailwater recovery ponds, on-farm water storage reservoirs, and other water conservation and quality practices. The plan aims to achieve environmental and economic benefits, including maintaining soil resources, improving water quality, and enhancing wildlife habitats.
