Owens Valley Groundwater Authority (OVGA), acting as a joint powers authority,The Owens Valley Groundwater Authority (OVGA), acting as a joint powers authority, approved the selection of DBS&A and team members Consensus and Collaboration Program, TEAM Engineering & Management, Inc., Stillwater Sciences, and Lechowicz & Tseng Municipal Consultants, to prepare a Groundwater Sustainability Plan (GSP) for the Owens Valley Groundwater Basin in Inyo and Mono Counties, California.

The GSP will guide future groundwater management and address the needs of the many stakeholders in the Basin, while bringing the groundwater resources into compliance with the California Sustainable Groundwater Management Act of 2014 (SGMA). The OVGA selected DBS&A’s team because of its broad expertise in the issues pertinent to groundwater sustainability planning, including:

  • Water rights acquisition
  • Agricultural water conservation
  • Watershed management
  • Funding for water resource projects
  • Database management systems
  • Stakeholder participation
  • Community planning
  • Groundwater resources assessments and safe yield evaluations
  • Conjunctive use
  • Water supply development
  • Feasibility studies
  • Water system engineering

Technical Support for GSP Development

The DBS&A team will be engaged in many activities, culminating in the submittal of the GSP to the California Department of Water Resources (DWR) by January 31, 2022. For example:

  • Data compilation, review, and management
  • Developing and implementing a stakeholder engagement/outreach program
  • Providing a technical evaluation of existing groundwater flow models
  • Preparing a description of the Basin setting and current and historic groundwater conditions
  • Developing a hydrogeologic conceptual model and water budget for the Basin
  • Developing sustainability criteria (undesirable results, sustainability goal, minimum thresholds, and measurable objectives)
  • Identifying management areas and specific projects necessary to maintain or achieve sustainability
  • Refining and consolidating of existing groundwater monitoring programs

GSP Expertise

Tony Morgan, P.G., C.HG., DBS&A’s Vice President and Principal Hydrogeologist, is leading our Owens Valley team as Project Manager. Mr. Morgan has expertise in SGMA compliance, including formation of GSAs, creation of GSPs, and conducting groundwater basin studies and regional conjunctive use programs. He collaborates with DBS&A’s hydrogeologists and modelers who support water agencies working toward compliance with SGMA, by developing and providing expert review of groundwater budgets and numerical models, estimating sustainable yields, and implementing groundwater monitoring programs and other groundwater management strategies.

In his role as  corporate Market Leader for Water Planning and Development, Tony draws upon his considerable expertise in SGMA compliance, including forming GSAs and GSPs, as well as regional conjunctive use programs. .

GSP Experience

This work for OVGA follows shortly behind our successful completion of the groundwater budgets for four groundwater basins for the Fox Canyon Groundwater Management Agency’s GSP development effort. DBS&A applied our distributed parameter watershed model (DPWM), which estimates key components of the groundwater/surface water balance, to reduce data uncertainties in the hydrologic balance to acceptable levels resulting in greater accuracy. DBS&A has successfully applied this technique at groundwater basins throughout southern California.

AIPG President, and Principal Hydrogeologist and co-founder of Clear Creek Associates, Doug Bartlett presented the award to Barb Murphy.

DBS&A Affiliate, Clear Creek Associates’ Senior Geologist Barb Murphy received the Ben H. Parker Memorial Medal at this year’s American Institute of Professional Geologists (AIPG) National Conference in Colorado Springs, Colorado.

The medal is awarded to individuals who have long records of distinguished and outstanding service to the profession. The most important criterion for this medal is a continual record of contribution to the profession of geology. A wide variety of contributions can be considered, such as: (a) the education and training of geologists, (b) professional development of geologists, (c) service to the Institute, (d) leadership in the surveillance of laws, rules, and regulations affecting geology, geologists and the public, and (e) activity in local and regional affairs of geologists.

Barb has served several times on the AIPG’s National Advisory Board, as Vice President, as 2012 National President, as chairperson of the AIPG annual meeting in Flagstaff, Arizona in 2008, and has been an active member on several AIPG specially-tasked committees. She worked with AIPG staff and AIPG headquarters in development of the Geosciences On-Line Initiative (GOLI) webinar program. As AIPG’s President, she worked to increase contact with members and to reorganize several sections. She worked with the Geological Society of London in developing an MOU for comity between the organizations for CPG and CGeol applications. Barb has represented geologists at the Arizona legislature and at conferences in matters related to professional standards and the importance of what geologists do.

SAWPA-AWQ-coverThe Santa Ana Regional Water Quality Control Board has adopted DBS&A’s ambient water quality determinations for total dissolved solids (TDS) and nitrate-nitrogen for all 37 of the groundwater management zones (GMZs) contained within the 2,840 square-mile Santa Ana Watershed in 2015.

DBS&A’s submittal of the updated 2015 TDS and nitrate-nitrogen ambient water quality (AWQ) determinations and assimilative capacity findings was accepted by the Santa Ana Water Board on March 23, 2018 as part of ongoing efforts to mitigate Basin Plan watershed salt loads. The Santa Ana Water Board’s acceptance further resolved that DBS&A report findings of ambient water quality was in compliance with the Salt Management Plan Monitoring Program Requirements that address TDS and nitrate in surface water and groundwater.

In issuing Resolution R8-2018-0027, the Santa Ana Water Board has directed staff to use DBS&A’s report of “…updated ambient TDS and nitrate-nitrogen determinations and assimilative capacity findings to develop appropriate waste discharge requirements or water recycling requirements.”

According to DBS&A’s Senior Vice President and Principal Hydrogeologist, Dr. Steve Cullen, PG, “DBS&A’s team of hydrogeologists, modelers, and data analysts have put together a remarkable product—we’re very proud of DBS&A’s contribution to the protection of water quality in the Santa Ana River Watershed.”

The 2015 ambient water quality determinations are currently being incorporated into the Santa Ana Watershed Project Authority’s One Water One Watershed (OWOW) 2018 Update to the Integrated Regional Water Management (IRWM) plan.

DBS&A’s TDS Trends Study, recently completed for the Southern California Salinity Coalition and the National Water Research Institute, by DBS&A is also being incorporated into the OWOW update. Click here to learn more.
