Madera Canal Capacity Restoration Project

By | US Bureau of Reclamation | No Comments
Project Title and Location: Madera Canal Capacity Restoration Project
Project Owner: US Bureau of Reclamation, Mid Pacific Region
Performance Period and Duration: 2014-2015
Project Role: Subcontractor to Water Resources Engineering
Scope and Complexity:

Madera Canal is supplied with water from Friant Dam, as part of the Central Valley Project. This canal starts at Friant Dam, approximately 18 miles northeast of Fresno, CA and ends in the city of Chowchilla, CA. The Madera Canal was designed and built in the early 1940’s to deliver water from Lake Millerton to the nearby farmlands through agreements with Madera Irrigation District and Chowchilla Water District. The canal geometry has been rehabilitated and modified over the years, nevertheless the current canal capacity is below its original design which is as follows:

  • Mile 0.33 to Mile 6.10: 1,275 cfs
  • Mile 6.10 to Mile 19.50 (Upper Boundary of Equalizing Reservoir): 1,075 cfs
  • Mile 21.78 (Lower Boundary of Equalizing Reservoir) to Mile 24.10: 1,000 cfs
  • Mile 24.1 to Mile 35.69:   750 cfs

Under a settlement agreement, the US Department of Interior agreed to analyze the feasibility of actions to restore the Madera Canal capacity and/or optimize the canal operations in order to improve the reliability of water deliveries to the contractors served by the canal. Actions are not limited to the canal geometry but will also include operations, control systems, and integration of other water supplies.

This project is performed under a contract to General Services Administration on behalf of the project owner, US Bureau of Reclamation, Mid Pacific Region. The Veridico scope is to support the plan formulation and the feasibility study reports. 

North of The Delta Offstream Storage (NODOS), Shasta, California

Project Title and Location: North of the Delta Offstream Storage (NODOS), Shasta, California
Project Owner: US Bureau of Reclamation, Mid Pacific Region, Sacramento, California
Performance Period and Duration: 2011
Project Role: Subcontractor to URS Corporation
Scope and Complexity:

The North of the Delta Offstream Storage (NODOS) investigation is co-sponsored by US Bureau of Reclamation and California Department of Water Resources. This investigation evaluates the feasibility of offstream storage in the northern Sacramento Valley for improved water supply and water supply reliability, improved water quality, and enhanced survival of anadromous fish and other aquatic species in the Primary Study Area and Extended Study Area. The purpose for the NODOS is to improve operational flexibility for water supply and hydropower by providing a new large integrated and efficient surface storage in an environmentally compatible manner. It is intended for the project to contribute to improved water quality, increased populations of anadromous fish and other aquatic species, and provide water for emergency releases in the event of a catastrophic failure of the Sacramento-San Joaquin Rivers Delta (Delta) levee system.

Three alternatives and the no action alternative were selected for further analysis of NODOS. Under the No Action/No Project Alternative, no actions would be taken to provide storage north-of-the-Delta to improve water supply reliability, or to enhance the survivability of anadromous fish and drinking water quality in the Delta. The three action alternatives include variable size reservoirs, and variations in conveyance and diversion rates from the existing Tehama-Colusa and Glenn-Colusa Irrigation District canals and the Sacramento River.

Veridico’s scope includes evaluation and review of hydrologic conditions and modeling results, and the development of various water supply management alternatives that are considered in the feasibility report prepared by URS Corporation.
