1242.1.
The diversion of floodflows for groundwater recharge shall not require an appropriative water right if all of the following conditions are met:
(a) (1) A local or regional agency responsible for flood management has given notice via its internet website, electronic distribution list, emergency notification service, or another means of public notice, that floodflows exist and, additionally, that floodflows downstream of the point of diversion are at imminent risk of flooding and inundation of land, roads, or structures.
(2) As used in this section, “floodflow” means any of the following:
(A) Where a water body is subject to a defined flood stage, flows in excess of flood stage where actions are necessary to avoid threats to human health and safety.
(B) (i) Except as provided in clause (ii), where a water body is not subject to a defined flood stage, surface water escaped from or is likely to imminently escape from a channel or water body causing or threatening to cause inundation of residential or commercial structures, or roads needed for emergency response. Likely imminent escape from a channel or water body shall be demonstrated by measured flows in excess of the maximum design capacity of a flood control project, where such a project is present and the maximum design capacity is readily available information.
(ii) This subparagraph does not apply to flows that inundate wetlands, working lands, or floodplains, events that constitute a “design flood,” groundwater seepage, or waters confined to a “designated floodway.”
(C) Where flows would inundate ordinarily dry areas in the bed of a terminal lake to a depth that floods dairies and other ongoing agricultural activities, or areas with substantial residential, commercial, or industrial development.
(D) Flows occurring downstream of a dam that is releasing water for flood control purposes as required by a United States Army Corps of Engineers flood control rule or curve, a court judgment, or other binding rule, if those releases exceed the claims of all known legal users and may be diverted without injury to any lawful user of water water, are not being released for environmental protection purposes, and are diverted using existing points of diversion. This subparagraph does not apply to flows that do not present an imminent threat of flooding and inundation of lands, roads, or structures.
(3) As used in this subdivision, “imminent” means a high degree of confidence that flooding and inundation will occur within 72 hours if flood management actions are not implemented.
(4) As used in this section, “excess water conditions” are determined pursuant to the Agreement Between the United States of America and the State of California for Coordinated Operation of the Central Valley Project and the State Water Project, as amended.
(b) The diversions cease when the flood conditions described in the public notice provided pursuant to paragraph (1) of subdivision (a) have abated to the point there is no longer a risk of flooding and inundation of land, roads, or structures downstream of the point of diversion.
(c) Any water diverted is not diverted to, and will not be applied to, any of the following:
(1) Any barns, ponds, or lands where manure or waste from an animal facility that generates waste from the feeding and housing of animals for more than 45 days per year in a confined area that is not vegetated are applied.
(2) Any agricultural field that has been identified as an outlier with respect to nitrogen application by any of the following:
(A) The board.
(B) The appropriate regional board.
(C) An agricultural coalition charged with implementation of the Irrigated Lands Regulatory Program.
(3) Any area that could cause damage to critical levees, infrastructure, wastewater and drinking water systems, drinking water wells or drinking water supplies, or exacerbate the threat of flood and other health and safety concerns.
(4) Any area that has not been in active irrigated agricultural cultivation within the past three years, including grazing lands, annual grasslands, and natural habitats. This limitation does not apply to facilities already constructed for the purpose of groundwater recharge or managed wetlands.
(d) (1) With respect to diversions from water tributaries to the Sacramento-San Joaquin Delta (Delta), water rights holders are not making releases of stored water or reoperating facilities to provide flow for the purposes of meeting water quality control plan or endangered species requirements in the Delta at the time of the diversion.
(2) For a diversion from the San Joaquin River or its tributaries upstream of Vernalis, water may be diverted only when the Delta is in excess water conditions and the Delta is without restrictions.
(3) With respect to all other diversions from the Delta or its tributaries, water may be diverted only when the Delta is in excess water conditions and either of the following applies:
(A) The Delta is without restrictions.
(B) The Delta is with restrictions, but Delta operations are only controlled by Old and Middle River flow or San Joaquin River inflow-to-export ratio.
(4) For diversions pursuant to paragraphs (1), (2), and (3), the diverter shall monitor conditions daily using the Delta Operations Summary report published on the internet website of the department daily, or a successor to that internet website adopted by the department, to determine the Delta’s condition and whether diversions are authorized pursuant to the permit.
(5) For purposes of paragraph (3), the term “controlled by Old and Middle River flow” means conditions when the Central Valley Project and the State Water Project are implementing one or more regulatory requirements by managing flows in Old and Middle River, whatever the source or content of those requirements is.
(e) The diversion of floodflows for groundwater recharge uses the following as part of the diversion:
(1) Either existing diversion infrastructure or temporary pumps.
(2) Existing groundwater recharge locations, where available.
(3) No new permanent infrastructure or permanent construction.
(4) For diversions directly from rivers or streams, protective screens on temporary pump intakes to minimize the impacts of diversion to fish and other aquatic life. Such screens shall be constructed of any rigid material, perforated, woven, or slotted, that provides water passage while physically excluding fish. The screen face shall be parallel to the flow and adjacent to the water’s edge. The upstream and downstream transitions to the screen structure shall be designed and constructed to minimize eddies upstream of, in front of, and downstream of the screen, while minimizing entrainment to the degree feasible. Before implementing this paragraph, the Department of Fish and Wildlife shall conduct at least one public workshop to review recommended design parameters and ranges of scenarios for deployment and use of protective screens. These recommendations and any other guidelines provided by the Department of Fish and Wildlife on the implementation of this paragraph shall not be subject to the Administrative Procedure Act (Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code).
(f) (1) Diversion for groundwater recharge pursuant to this section shall not create a vested water right to divert, even of a temporary nature. This limitation is on the authorization to divert and not a limitation on the authorization for beneficial use of the water diverted to underground storage.
(2) In a groundwater basin being managed pursuant to a groundwater sustainability plan that the department has determined is likely to achieve the sustainability goal for the basin pursuant to Chapter 10 (commencing with Section 10733) of Part 2.74 of Division 6, including a determination pursuant to Section 10733, the groundwater sustainability agency may grant a person or entity making the diversion an allocation credit. The allocation credit granted by the groundwater sustainability agency shall not exceed the amounts of water reported in the filings required pursuant to subdivision (g).
(g) (1) The person or entity making the diversion for groundwater recharge files all of the following with the board and with any applicable groundwater sustainability agency, as defined in Section 10721, for the basin:
(A) A notice that provides the information specified in subparagraphs (A) through (C), inclusive, of paragraph (2), 48 hours before whenever feasible, and in no event later than 48 hours after initially commencing diversion of floodflows for groundwater recharge.
(B) A preliminary report no later than 14 days after initially commencing diversion of floodflows for groundwater recharge.
(C) A final report no later than 15 days after diversions cease.
(2) The preliminary and final reports shall do all of the following:
(A) Identify the person or entity making the diversion for groundwater recharge.
(B) Provide the Global Positioning System (GPS) coordinates for the point of diversion, a map identifying the approximate area inundated by the floodflows, and the corresponding assessor parcel numbers.
(C) Identify the time when diversions of floodflows to groundwater recharge commenced, and, for final reports, when diversions ceased.
(D) Provide an estimate, as of the report’s date, of the amount of floodflows diverted for groundwater recharge.
(h) (1) The diversion of floodflow for groundwater recharge pursuant to this section shall be exempt from the requirements of Division 13 (commencing with Section 21000) of the Public Resources Code and Chapter 6 (commencing with Section 1600) of Division 2 of the Fish and Game Code, if the diversion does not otherwise require a discretionary permit and is carried out consistent with all requirements of this section, including no permanent construction. Notwithstanding any other law, and regardless of whether an action described in this subdivision is exempt from environmental review under the California Environmental Quality Act (Division 13 (commencing with Section 21000) of the Public Resources Code) or any other law, a lead agency shall provide notice to and consult with California Native American tribes in accordance with Sections 21074, 21080.3.1, 21080.3.2, 21082.3, 21084.2, and 21084.3 of the Public Resources Code before approving or carrying out an action described in this subdivision, and a decisionmaking authority may impose conditions of approval as part of the action to avoid or mitigate potential impacts to tribal cultural resources.
(2) The person or entity making the diversion shall contact the Department of Fish and Wildlife to determine whether the Department of Fish and Wildlife has recommendations for appropriate species protection and shall consider implementing those recommendations to the extent possible during the diversion of floodflow. The Department of Fish and Wildlife’s recommendations, if any, shall be consistent with what is practicable during floodflow conditions.
(i) This section shall apply only to diversions commenced before January 1, 2034.
