Should the state open the Kings River to new water permit applications?
The State Water Board's water rights office says up to 1.13 million acre feet of Kings River water goes unused, and an Administrative Hearing Office hearing on January 19, 2027 will consider revoking the river's 1967 fully appropriated designation. Revocation would open the Kings River to new water permit applications, which matters for irrigation districts, groundwater agencies and water storage operators in the Central Valley.
Why it matters
The fully appropriated designation, set in 1967 when the Water Board had limited information about Kings River flood flows, has blocked new permit applications for decades. Pending applications from Semitropic Water Storage District (filed in 2017), a joint filing by Consolidated, Alta and Fresno irrigation districts, and a later application from McMullin Area Groundwater Agency now depend on whether that designation holds.
The state water rights office puts unused Kings River water at up to 1.13 million acre feet, while flows through the James Bypass fell from 2.3 million acre feet in 1983 to 767,000 acre feet in 2023. Semitropic's pending application seeks to divert up to 1,200 cubic feet per second during flood release.
The players
State Water Resources Control Board
California's state agency that issues and administers water rights and can designate rivers as fully appropriated.
Semitropic Water Storage District
A Kern County water district that operates groundwater banking and recharge projects and filed the 2017 Kings River flood flow application.
Consolidated Irrigation District
A Kings River irrigation district that has delivered river water since 1876 and joined a pending application with Alta and Fresno irrigation districts.
The details
Semitropic's application would divert water from the river during flood release into the California Aqueduct, and hold it in its flood water recharge project in Kern County. Under the current designation, applications like this face a legal barrier because the river is classified as fully appropriated. Revoking the 1967 designation would remove that barrier and allow new permit applications to move forward. The dispute has moved slowly, with the last Administrative Hearing Office proceeding held in 2024.
Timeline
1967: The Kings River was designated fully appropriated, 13 years after Pine Flat Dam became operational.
2017: Semitropic Water Storage District filed its application for Kings River flood flows.
2024: The last Administrative Hearing Office proceeding on the dispute was held.
January 19, 2027: The Administrative Hearing Office will hold a hearing on revoking the designation.
Market Landscape
The dispute sits within a long-running contest over California's surface water, where the Water Board's 1967 designation has shaped which projects can secure new supply. Pending applications from water districts and groundwater agencies show competing demand for flood flows that have gone unused.
Water districts, groundwater agencies and storage operators in the Kings River basin should track the January 2027 hearing, since a revoked designation would open the river to new permit applications. Businesses that depend on irrigation or groundwater supply should consult qualified water counsel before making planning decisions tied to this outcome.
The takeaway
Watch the January 19, 2027 Administrative Hearing Office hearing as the decisive event for any Kings River water project. Operators with water-dependent operations should review their supply assumptions with qualified water counsel ahead of that date.
What happens next
The Administrative Hearing Office will hold a hearing on January 19, 2027 on whether to revoke the Kings River fully appropriated stream designation.
