Nampa & Meridian Irrigation District (District or NMID) plans to modernize the headworks of the Ridenbaugh Canal diversion by: replacing the existing diversion structure, which uses check boards, with a new structure that uses pneumatic bladder dams; replacing the existing 550’ sediment control structure and catwalk with new; replacing the existing weed and debris rack with a new self-cleaning rack, and installing the necessary electrical, pneumatic, and mechanical systems to operate the automated diversion. The completed structure should effectively divert water to the Ridenbaugh Canal System in a way that minimizes risks to the District, allows for user-friendly operation and maintenance, and takes advantage of current technology to produce benefits for the District, for the river system, and the environment.
