California Salmonid Stream Habitat Restoration Manual

California Department of Fish and Wildlife (CDFW) | August 6th, 2010

Summary

The first edition of this manual, written by Gary Flosi and Forrest Reynolds, and published in 1991, formally synthesized and described the Department of Fish and Game's

The first edition of this manual, written by Gary Flosi and Forrest Reynolds, and published in 1991, formally synthesized and described the Department of Fish and Game's approach and technical methods for anadromous salmonid habitat restoration. From 1991 through 1994 the first edition was broadly distributed and used as a "standard methods" text by many habitat restoration and resource inventory workers. As a result, many suggestions for improvement of the manual were received by the authors. The second edition, by Flosi and Reynolds was supported by a team that included the authors of this third edition, and was published in October of 1994. The second edition included a number of revisions: 1) a reorganization of sections for project planning and project implementation; 2) the just then recently revised stream channel classification system developed by David Rosgen; 3) a new monitoring and evaluation section; 4) a listing of all databases used for resource inventory and analysis as presented in the manual; 5) a protocol for a large woody debris inventory; 6) a description of required environmental review processes and permits; 7) an expanded and updated listing of sensitive species; and 8) numerous editorial changes to text and data forms. The third edition, like the second, incorporates changes recently developed in the practice of stream habitat inventory and restoration. The authorship list has changed with this edition to more accurately reflect the contributions of the writing team members. The manual is presented in binder form in this edition to more easily and economically incorporate future additions and developments as they evolve. This fourth edition incorporates all changes, corrections, and revisions of this manual up to July 2010. The manual continues in binder form in this edition to easily and economically incorporate future additions and developments as they evolve. The authors anticipate the continued widespread distribution and use of this manual will promote the implementation of the restoration techniques. Readers should also be aware that computer data entry and data summary programs are available upon request for all data collection protocols presented in this manual. Updates to this manual are available on line at http://www.dfg.ca.gov/fish/Resources/HabitatManual.asp.

California Simulation of Evapotranspiration of Applied Water and Agricultural Energy Use in California

Journal of Integrative Agriculture (Elsevier) | August 5th, 2013

Summary

The California Simulation of Evapotranspiration of Applied Water (Cal-SIMETAW) model is a new tool developed by the California Department of Water Resources and t

The California Simulation of Evapotranspiration of Applied Water (Cal-SIMETAW) model is a new tool developed by the California Department of Water Resources and the University of California, Davis to perform daily soil water balance and determine crop evapotranspiration (ETc), evapotranspiration of applied water (ETaw), and applied water (AW) for use in California water resources planning. ETaw is a seasonal estimate of the water needed to irrigate a crop assuming 100% irrigation efficiency. The model accounts for soils, crop coefficients, rooting depths, seepage, etc. that influence crop water balance. It provides spatial soil and climate information and it uses historical crop and land-use category information to provide seasonal water balance estimates by combinations of detailed analysis unit and county (DAU/County) over California. The result is a large data base of ETc and ETaw that will be used to update information in the new California Water Plan (CWP). The application uses the daily climate data, i.e., maximum (Tx) and minimum (Tn) temperature and precipitation (Pcp), which were derived from monthly USDA-NRCS PRISM data (PRISM Group 2011) and daily US National Climate Data Center (NCDC) climate station data to cover California on a 4 km×4 km change grid spacing. The application uses daily weather data to determine reference evapotranspiration (ETo), using the Hargreaves-Samani (HS) equation (Hargreaves and Samani 1982, 1985). Because the HS equation is based on temperature only, ETo from the HS equation were compared with CIMIS ETo at the same locations using available CIMIS data to determine correction factors to estimate CIMIS ETo from the HS ETo to account for spatial climate differences. Cal-SIMETAW also employs near real-time reference evapotranspiration (ETo) information from Spatial CIMIS, which is a model that combines weather station data and remote sensing to provide a grid of ETo information. A second database containing the available soil water holding capacity and soil depth information for all of California was also developed from the USDA-NRCS SSURGO database. The Cal-SIMETAW program also has the ability to generate daily weather data from monthly mean values for use in studying climate change scenarios and their possible impacts on water demand in the state. The key objective of this project is to improve the accuracy of water use estimates for the California Water Plan (CWP), which provides a comprehensive report on water supply, demand, and management in California. In this paper, we will discuss the model and how it determines ETaw for use in water resources planning.

California State Auditor report on California Water Fix planning efforts

California Department of Water Resources (DWR) | October 4th, 2017

Summary

As requested by the Joint Legislative Audit Committee, the California State Auditor presents this audit report concerning the Department of Water Resources’ (DWR) manag

As requested by the Joint Legislative Audit Committee, the California State Auditor presents this audit report concerning the Department of Water Resources’ (DWR) management of the planning efforts for the California WaterFix Project (WaterFix). WaterFix is intended to address environmental and water supply reliability issues related to pumping water from the Sacramento?San Joaquin Delta (the Delta). Planning began in 2006 on the development of the Bay Delta Conservation Plan (BDCP), which consisted of several measures or activities for restoring the Delta and improving water reliability. Subsequently, in 2008 DWR initiated the Delta Habitat Conservation and Conveyance Program (conservation and conveyance program) to evaluate how to implement the BDCP and alternatives to it, including evaluating the environmental impacts and completing preliminary engineering work. Through the evaluation effort, DWR identified one of the alternatives—WaterFix—as its preferred approach. This report concludes that the planning phase experienced significant cost increases and schedule delays because of the scale and unexpected complexity of the project. For example, costs of the conservation and conveyance program’s efforts to evaluate and plan for the potential implementation of the BDCP and its alternatives, which eventually included WaterFix, increased significantly. As of June 2017, the planning costs had reached $280 million. We also found that DWR did not follow state law when it replaced the program manager for the conservation and conveyance program. Specifically, DWR selected the Hallmark Group (Hallmark) to provide program management services without advertising a request for qualifications, and DWR could not demonstrate that it ever evaluated Hallmark’s qualifications for this role. The cost of DWR’s current contract with Hallmark has tripled from $4.1 million to $13.8 million. Additionally, DWR has not completed either an economic or financial analysis to demonstrate the financial viability of WaterFix. Finally, it has not fully implemented a governance structure for the design and construction phase, and has not maintained important program management documents for WaterFix.
