Toggle Image Agricultural Drainage in the San Joaquin Valley: A Gap Analysis (Draft) 10/01/2002 (PDF, 804 KB)
Description: California’s San Joaquin Valley is one of the world’s most vital and productive farming areas. The westside of the San Joaquin Valley is a fertile yet arid landscape where commercial agriculture is viable with supplemental irrigation and soil fertilization. The importation of surface water and use of groundwater for irrigation as well as fertilizers results in the addition of salts to agricultural lands in addition to naturally occurring salt. The leaching requirement to remove salt from the crop root zone to maintain soil quality and productivity results in the deep percolation of applied water. Agricultural lands of the westside SJV are underlain by a low permeability clay layer without adequate drainage, causing a shallow water table to rise toward the soil surface.

The Activity is consistent with the 1990 Management Plan’s recognition that the plan be updated from time to time as monitoring, additional studies, and local actions reveal new facts, as well as the 1991 Implementation Strategy which states that " . . . Management Group will sponsor an effort to periodically update the Management Plan." The Activity Plan consisted of three phases: Phase I was a technical evaluation of drainage options by technical committees and a concurrent evaluation and assessment of the 1990 Plan implementation by three subarea committees.

Toggle Image Groundwater Management Final Report: San Joaquin Valley Drainage Implementation Program 04/01/1999 (DOC, 726 KB)

By examination of previous work on the problem, we specifically address technical feasibility of maintaining a deeper water table and substantially reducing groundwater discharge to drains by increasing groundwater pumping while reducing applied water over the region. Further, we discuss the potential water quality impacts of lowering the water table by increasing pumping.
Toggle Image Land Retirement Final Report: San Joaquin Valley Drainage Implementation Program 02/10/1999 (PDF, 517 KB)
Description: The initial scientific documentation which provided the basis for the choice of management alternatives, including land retirement, was an important part of the SJVDP. An extensive library (e.g., SJVDP, 1989; SJVDP, 1990, pages 163-175) of supporting measurements, technical analysis, maps, and models exist to help quantify drainage conditions, understand drainage management, and assess the benefits from a regionally implemented plan. The initial assessment included a compilation of historical data, execution of baseline field studies for the period 1985 through 1988, and development of planning objectives, criteria, and performance standards based on water-quantity, water-quality (i.e., protection of aquatic life, wildlife, and public health) and land use (SJVDP, 1990, Tables 7, 15, 16).
Toggle Image Evaporation Ponds Final Report: San Joaquin Valley Drainage Implementation Program 02/02/1999 (PDF, 614 KB)
Description: Evaporation basins along with other alternative drainage management options play a major role in sustaining agriculture in drainage impacted lands, particularly the Tulare/Kern sub-area. However, the presence of naturally occurring selenium in the impounded drainage waters is of concern to wildlife, especially waterbirds. From 1989 to the present, adverse selenium impacts to American avocet and black-necked stilts have been studied extensively in the environs of Tulare Lake Basin. Modifications in the design and management of evaporation basins have been implemented. For those basins with impacts on waterbirds, site-specific mitigation measures have been adopted such as compensation and alternative habitats.
Toggle Image Drainage Reuse Final Report - San Joaquin Valley Drainage Implementation Program 02/01/1999 (PDF, 554 KB)
Description: Reuse of saline drainage water is one management option on the west side of the San Joaquin Valley (SJV) for reducing the volume of drainage water (San Joaquin Valley Drainage Program, 1990). Management practices that result in less drainage water are attractive since they would reduce the area required for environmentally sensitive evaporation ponds, reduce the area for solar ponds and reduce the costs associated with disposal of the final effluent. In conjunction with other drainage management options such as source control and a means of removing salt and trace elements out of the valley, reuse could have additional benefits such as: (a) increase water use efficiency; (b) optimize production and environmental quality of irrigated farmland; (c) improve environmental quality of rivers and other water bodies; and (d) enhance ....
Toggle Image Drainage Water Treatment Final Report: San Joaquin Valley Drainage Implementation Program 02/01/1999 (PDF, 224 KB)
Description: This review identifies and evaluates research findings on various treatment options for selenium removal and disposal of salts in the San Joaquin Valley, California. Selenium from agricultural drainage water has the potential to bioaccumulate at high enough levels in plants and animals so as to cause mortality and to impair reproduction of fish and aquatic birds. The selenium link between agricultural drainage and impacts on birds was first documented in 1983 by U.S. Fish and Wildlife Service studies at Kesterson Reservoir in the SJV. Aquatic plants, invertebrates, fish, frogs, snakes, birds and mammals at Kesterson Reservoir contained elevated selenium levels, often averaging a 100-fold increase over samples collected for similar species at reference sites (Ohlendorf, 1989; Ohlendorf and Santolo, 1994).
Toggle Image Source Reduction Final Report: San Joaquin Valley Drainage Implementation Program 02/01/1999 (DOC, 289 KB)
Description: Currently, limited drainage water disposal is permitted into the an Joaquin River from areas in the northern part of the SJV and to evaporation ponds in the Tulare/Kern subarea. Many options such as deep-well injection, desalination, water treatment to remove lenium have been investigated, but were found to be either technically, environmentally, and/or economically unsatisfactory. Presently limited disposal options for subsurface drainage means that drainage systems are not now viable for many areas of the Valley. While some disposal options (water treatment, drain water reuse) continue to be investigated, reducing the amount of subsurface drainage water through source reduction will play a major role in dealing with problems caused by the shallow, saline groundwater.
Toggle Image Salt Utilization Final Report: San Joaquin Valley Drainage Implementation Program 02/01/1999 (DOC, 428 KB)
