Water Planning Projections


The Nevada Irrigation District presented updated Water Planning Projections to its Board of Directors on Wednesday, August 26, 2020.   Another meeting to provide clarification of the Technical Memorandums was held on September 24, 2020. After the presentation and a review of the public comments, the Technical Memorandums were finalized on November 12, 2020. 

The Water Planning Projections consist of three studies that analyze the hydrology, water supply, and water demand that help NID determine if its water storage and delivery system will provide sufficient water to meet customer demands over time and under variable conditions.

The Water Planning Projections are used to prepare a number of planning reports such as the Urban Water Management Plan and the Agricultural Management Plan, which are required to be updated and submitted to the State of California every five years. The Water Planning Projections are also used to prepare the District’s Plan for Water, formerly called a Raw Water Master Plan, and is considered when making decisions about capital improvements to its water storage and delivery system.

The need to update NID’s Water Planning Projections is driven by a series of requirements and assumptions, including the new Yuba-Bear System Federal Energy Regulatory Commission (FERC) regulatory requirements, state-derived climate change data, and the state-mandated planning requirements. Together, these requirements and assumptions constitute significantly new planning assumptions and drive the need to update and revise NID’s Water Planning Projections when necessary.
