Groundwater Policy Questions

• Local Management or State control?

• Definition of “Sustainability”?

• Transparency? More Data?

• How to address Nitrates in Drinking Water?

• How to protect Groundwater Dependent Ecosystems?

Kings Service Area Characteristics

• Kings Groundwater Basin– 976,000 acres– 93 MAF of storage to 1,000 ft (2003 Bulletin 118)

• Tulare Lake Groundwater Basin– 524,000 acres– 12 MAF of storage to 300 ft (DWR 1995)

8

Critical Condition

• Overdraft– Increasing demand– Reduced Surface Supply reliability

• Water Quality– Nitrates

9

• Kings Basin Overdraft– Regional Supply Characteristics: closed system, conjunctive use basin.

– Average annual overdraft (1963 to 2009) approx. 120 TAF.

– Largest GW depression located near Raisin City, beyond the Kings River place of use.

ACWA Groundwater Task ForcePolicy Objectives

13

Local Management

• SB 1938 (2002)– Amended AB 3030 (January 1, 1993) – Local planning/stakeholder involvement– Establish Basin Management Objectives

• Groundwater levels• Groundwater Quality• Subsidence• Surface/Groundwater Relationship

– Implement Monitoring

• 23 agencies in the two basins have updated AB 3030 Plans to SB1938 standard

Water Board Recommendations

• Providing Safe Drinking Water– New funding

• Monitoring, Assessment, and Notification– Private well testing

• Nitrogen Tracking and Reporting– Mass balance tracking

• Protecting Groundwater– CDFA programs

Drinking Stakeholder Group Accomplishments

IRWM Plan Goals

• Halt, and ultimately reverse, the current overdraft and provide for sustainable management of surface and groundwater

• Increase the water supply reliability, enhance operational flexibility, and reduce system constraints

• Improve and protect water quality

• Provide additional flood protection

• Protect and enhance aquatic ecosystems & wildlife habitat
