Ground Water Recharge

Ground Water Recharge: A Pathway Toward Regional Environmental Improvement and Water Supply Security

Presentation to ECOS Board 
September 25, 2018 at 6 PM

The current and future water supply security for residential, commercial, industrial, agricultural, and conservation landowner customers in the Sacramento Region (Region) appears to be satisfactory when one reviews the water supply assessments contained in each of the Region’s water purveyors’ Urban Water Management Plans. However, some of these plans do not fully address the implications of climate change on the future availability of water supplies. The recent drought has shown limitations in some of the Region’s water supply systems, and climate scientists predict the frequency and severity of droughts will increase. The State Legislature has moved to ensure the increased frequency and severity of droughts along with other weather changes due to climate change, are planned for in future Urban Water Management Planning cycles. A more comprehensive understanding of the reliability of the Region’s water supplies will be known, once the impact of the Region’s changing climate is fully understood and planned for by all Regional water purveyors.

Save Our Groundwater!

June 6, 2018

The Environmental Council of Sacramento (ECOS) filed a comment in March of 2017 on the Sacramento Central Groundwater Authority’s (SCGA) petition to be deemed an acceptable “alternative plan” under the Sustainable Groundwater Management Act (SGMA). The purpose of our June 6, 2018 letter is to reiterate our opposition to that petition and to urge the Department of Water Resources (DWR) again to find that SCGA is not in compliance with SGMA.

Some highlights:

  • groundwater levels continue to fall in the portions of the basin that most affect the important ecological resources of the lower Cosumnes watershed
  • SCGA continues to make little effort to encourage or facilitate public engagement in its ongoing deliberations
  • SCGA does no targeted outreach, apparently maintains no list of interested parties, and has a web site that is of very limited usefulness
  • SCGA needs to recognize that public engagement is a key component of SGMA compliance
  • SCGA is currently reassessing its rate structure and could adjust its rates to account for costs of both plan preparation and projects/programs to which they have committed and to date ignored

Sacramento Central Groundwater Authority “South American Sub-basin Alternative”

March 31, 2017

ECOS has submitted the following letter to provide comment, and questions, regarding SCGA’s proposal that its existing Groundwater Management Plan (GMP) be accepted as an adequate Alternative to developing a Groundwater Sustainability Plan (GSP) as required by the Sustainable Groundwater Management Act (SGMA).

Project Location:  The figure below shows the location of the South American Subbasin (located in the central portion of Sacramento County), the existing SCGA GMP area, and portions of the adjacent California Department of Water Resources’ (State DWR’s) Bulletin 118 (2003) groundwater subbasins located within Sacramento County.
