D4: Fish Habitat and Passage Improvement*

About This Project

>> Click Here for Further Information about the Almaden Lake Improvement Project >>

This project helps restore and maintain healthy steelhead trout populations by improving fish passage and habitat. Possible work sites include Alamitos Creek at Almaden Lake and Ogier Ponds in the Coyote watershed, where man-made creek alterations disrupt fish migration. The project also includes studies of steelhead streams throughout the county to determine where improvements are needed to support spawning, rearing and migration. Funding also pays for the development of a program to use large woody debris to create fish habitat.

 

*This project was voter approved as part of the Safe, Clean Water and Natural Flood Protection Program.

Key Performance Indicators for the Safe, Clean Water Program 

KPI #1: Complete planning and design for 2 creek/lake separations.

  • Site 1: Almaden Lake - Public review of the draft EIR for the Almaden Lake Project is expected by December 2019. 

  • Site 2: Ogier Ponds - In October 2018, the Board approved a budget adjustment to provide Safe, Clean Water funds for completion of a planning study.  The Board directed staff to work with the landowner, Santa Clara County Parks, to develop a Memorandum of Agreement (MOA) to begin the planning study.  The MOA is currently awaiting County Parks review and approval.

KPI #2: Construct 1 creek/lake separation project in partnership with local agencies. 

  • Currently 2 projects are in the planning phase and 1 will receive construction funding from the Safe, Clean Water Program. 

KPI #3: Use $6 million for fish passage improvements. 

  • Valley Water completed final design for the Bolsa Road Fish Passage Project. The Project will be advertised for bids in January 2020 with construction to begin in May 2020. The construction of the Project will be completed by the end of 2020.

  • The City of San José has completed a feasibility study related to the removal of the Singleton Road fish passage barrier. Valley Water is working on a partnership agreement with City of San José to provide support for City's effort to remove the Singleton Road Bridge and associated channel restoration. 

  • The Evelyn Bridge Fish Passage within Stevens Creek completed construction on November 21, 2015.

KPI #4: Conduct study of all major steelhead streams in the county to identify priority locations for installation of large wood debris and gravel as appropriate.  

  • The consultant contract to conduct a Phase 2 study covering remaining steelhead streams including Llagas Creek, Pacheco Creek, Los Trancos Creek, San Francisquito Creek, Calero Creek and the Pajaro River was approved by the Board during the June 25, 2019, Board meeting. The review of the relevant information and the refinement of selection criteria and tool developed during the Phase 1 study are currently underway.  The study will recommend high-priority locations for future gravel augmentation/large woody debris placement projects along the selected creeks; using selection criteria based on biological, geomorphic and flood risk consideration as well as site visits, to narrow down to 14 recommended locations covering all six (6) creeks.

KPI #5: Install large woody debris and/or gravel at a minimum of 5 sites (1 per each 5 major watersheds). 

  • In August, Valley Water completed the construction work of the Los Gatos Creek Gravel Augmentation and Large Woody Debris Placement Project located just downstream of Highway 17, one of Phase 1 Study recommended priority locations.  Gravel and large woody debris placement improves fish habitat by adding suitable creek bed materials for food and spawning and adds complexity to streamflow by reducing velocity and promoting channel stability, allowing riffles to form. These habitat complexities make it easier for fish to migrate provide areas to rest and seek refuge from predators. These modifications improve stream conditions for both adult and juvenile steelhead, as well as other native fish in the watershed.

About the Safe, Clean Water and Natural Flood Protection Program

In November 2012 the voters of Santa Clara County overwhelmingly approved Measure B, the Safe, Clean Water and Natural Flood Protection Program, as a countywide special parcel tax for 15 years with a sunset date of June 30, 2028. This Program replaced the Clean, Safe Creeks and Natural Flood Protection Plan, which voters approved in November 2000.

The Safe, Clean Water Program was developed with input from more than 16,000 residents and stakeholders and was created to match the community’s needs and values. The voters of Santa Clara County identified five priorities:

Priority A: Ensure a Safe, Reliable Water Supply

Priority B: Reduce Toxins, Hazards and Contaminants in our Waterways

Priority C: Protect our Water Supply from Earthquakes and Natural Disasters

Priority D: Restore Wildlife Habitat and Provide Open Space

Priority E: Provide Flood Protection to Homes, Businesses, Schools and Highways

Other: Six projects from the Clean, Safe, Creeks Plan have been carried forward into the Safe, Clean Water Program.  

Each year, Valley Water prepares a report providing a progress update for each of these Program priorities, along with fiscal year accomplishments.

To ensure transparency and accountability to the voters, the ballot measure also created an Independent Monitoring Committee, appointed by the Santa Clara Valley Water District Board of Directors. The Independent Monitoring Committee annually reviews the Program’s progress to ensure the outcomes are achieved in a cost-efficient manner and reports its findings to the Board.

In addition, the Program requires three independent audits, the first of which was conducted in FY 2017.
