Groundwater Management in the Kings River Service Area David Orth Kings River Conservation District
Overview • Formed in 1951 by special act • A leading resource management agency for the Kings River region Environmental Stewardship Water Power
Current Regional Programs Groundwater Management Upper Kings Basin Integrated Regional Water Management Plan (IRWMP) Kings Basin Coordinated Groundwater Management Group California Statewide Groundwater Elevation Monitoring (CASGEM) Irrigated Lands Regulatory Program Agricultural Water Enhancement Program
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?
Tulare Lake Hydrologic Region: 10.9 million acres, 12 distinct Basins/7 sub-basins

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)
Critical Condition • Overdraft • Increasing demand • Reduced Surface Supply reliability • Water Quality • Nitrates
Groundwater Conditions • 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.

Groundwater Policy Recommendations Association of CA Water Agencies California Water Foundation Natural Heritage Institute Others
ACWA Groundwater Task Force Policy Objectives
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
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
