NID’s Plan for Water process continues on Tuesday, May 23. This meeting will focus on a presentation, “Global Climate Projections and Unimpaired Hydrology,” by West Consultants. The workshop will start at 4:00 p.m. at NID’s main office and also via Zoom. 

Overview of current Plan for Water stages:


This stage will seek to determine design assumptions, principles, and standards of data-driven modeling as it relates to the hydrology and hydrography of NID’s water systems while reconfirming previous efforts of FERC re-licensing models and determining appropriate climate and drought scenario analysis. 


This stage will seek to determine the District’s future demand scenarios as they pertain to land use designations, growth projections, water use trends, and environmental & regulatory demands. 


This stage will seek to determine the District’s future supply scenarios as they pertain to land use designations, growth projections, water use trends and environmental & regulatory demands.

Recap of April 11 Meeting:

NID staff provided an overview of the Hydrologic Modeling System (HEC-HMS). HEC-HMS is used for simulating the precipitation-runoff processes of drainage basins, including large river basin water supply, flood hydrology, and small urban or natural watershed runoff.

Looking ahead to May 23 and beyond:

Next, the May 23 meeting will focus on a presentation, “Global Climate Projections and Unimpaired Hydrology,” by West Consultants. The stated objectives here are to develop unimpaired hydrology representative of historical conditions, ensure compatibility with HEC-ResSim, and to support NID’s Plan for Water process.

NID recently published a revised planning matrix, which, in addition to outlining the content of each stage, outlines the proposed schedule for the Plan for Water process. According to the revised schedule – NID plans to complete the Plan for Water process by August 2023. That said – things are moving very quickly at this point. We need to ensure that proper time and attention is given to each stage, particularly as we get into more substantive conversations around demand.

Join the meeting tomorrow at 4pm and be prepared to ask NID questions about the updated planning matrix and truncated schedule for Plan for Water.

See meeting materials below, for additional detail.

NID’s community partners and allies are ready and willing to be of assistance in the planning process. As Plan for Water progresses, it will be essential that key stakeholders, experts, and community members are utilized to help inform the decision-making process, as we believe that the best policies are informed by science and data. SYRCL will continue to be an active participant in the Plan for Water Process and encourages the public to stay informed and engaged as well. 

Join the Plan for Water Meeting either in person or virtually on May 23.
