Fully Contained Springs Exemption Process
This page provides information regarding the Fully Contained Springs Exemption outlined in the Cannabis Cultivation Policy – Principles and Guidelines for Cannabis Cultivation (Cannabis Cultivation Policy). The Cannabis Cultivation Policy allows cannabis cultivators to request an exemption from the need for a Cannabis SIUR if the spring used for cannabis cultivation activities meets the specific requirements outlined in the Cannabis Cultivation Policy.

Fully Contained Springs
Fully contained springs do not flow off a person’s property in the absence of diversion, including during wet years, or after periods of heavy rain. The Cannabis Cultivation Policy allows cultivators to request an exemption from certain flow requirements if the spring being used for cannabis cultivation meets a set of pre-determined conditions. The full text of requirements can be found in the Minimum Requirements to be Included in a Fully Contained Spring Exemption Report.
The determination of whether a spring is fully contained, and whether a cultivator may be exempt from certain flow conditions, is the responsibility of the State Water Resources Control Board (State Water Board). The information below describes: 1) the process to apply for a fully contained spring exemption; and 2) the information that is to be submitted in support of the exemption.
Requesting a Fully Contained Spring Exemption
Cannabis cultivators requesting an exemption must request a Cannabis Small Irrigation Use Registration (Cannabis SIUR) and include supporting evidence regarding the fully contained spring. All requests for fully contained spring exemptions must be submitted through the State Water Board’s online Cannabis Cultivation Program Application Portal (Portal). Division of Water Rights staff will evaluate the spring data provided in the Portal application and will assign one of three possible outcomes:
- The claim is accepted without further action from the applicant. The spring is considered fully contained and no SIUR will be issued.
- The claim is rejected for falling within a riparian buffer for a watercourse or the potential for runoff from the spring to flow beyond the bounds of the parcel. There is no option to submit a report. The spring cannot be considered fully contained and an SIUR will be issued. The applicant may divert under the SIUR conditions.
- The claim is conditionally rejected. The spring is not considered fully contained and an SIUR will be issued. The applicant may divert under the SIUR conditions. The applicant may challenge this decision by hiring a Qualified Professional to write a Fully Contained Spring report that meets specific conditions outlined below.
Only in case 3 is a Qualified Professional needed to write a report. Reports submitted under Cases 1 or 2 will not be considered. The report must include supporting evidence prepared by a Qualified Professional and must include information provided in the Minimum Requirements to be Included in a Fully Contained Spring Exemption Report (Updated November 25, 2019) to be considered.
Submittal of Exempt Springs Request through Portal.
- The Portal will guide you through questions related to your cultivation site and source(s) of water. You will need to complete the Cannabis SIUR application, including all questions related to your water source(s), and submit the Cannabis SIUR filing fee.
- After you complete your Cannabis SIUR application, the State Water Board will email you a Notice of Receipt for the Cannabis SIUR. The Cannabis SIUR Notice of Receipt will include confirmation that the State Water Board has received your fully contained spring exemption request and will provide information on how to submit fee payments. (Note you will obtain a separate Notice of Receipt for coverage under the Cannabis General Order.)
- Once you have received the Cannabis SIUR, you may divert from the spring. The diversion must comply with specific requirements for diversion from fully contained springs, which can be found in the Cannabis Cultivation Policy – Narrative Flow Requirements.
- You may submit the Cannabis SIUR with your California Department of Food and Agriculture’s CalCannabis License Application as verification of your water source(s) and fully contained spring claim.
The Portal is available at: https://public2.waterboards.ca.gov/mt/sites/site?siteName=CGO
Approval or Denial of Fully Contained Spring Requests. State Water Board staff may request additional information or conduct a site visit to assess the request. Following review of the request and any additional information, the State Water Board will approve, deny, or conditionally deny the fully contained spring exemption request. The State Water Board will notify the cannabis cultivator of the approval or denial of the request.
- If approved, the cannabis cultivator is still subject to all applicable requirements of the Cannabis Cultivation Policy. They will not be issued an SIUR.
- If the fully contained spring request is denied, the cannabis cultivator will be issued a Cannabis SIUR with a water right priority date of the initial Cannabis SIUR submittal date.
- If the fully contained spring request is conditionally denied, the cannabis cultivator may choose to hire a qualified professional to prepare and submit a Fully Contained Spring Report to be evaluated by State Water Board staff.

Submittals received after November 25, 2019, shall include the Certification Statement(s) described in the List of Minimum Information to be submitted for Fully Contained Spring (Updated November 25, 2019)
*If a professional classification is not listed above, an individual may request that a new professional classification be approved by the Deputy Director for Water Rights (Deputy Director) The request and supporting evidence, should be submitted by email to: DWR-CannabisReg@waterboards.ca.gov.
Individuals who do not have one of the professional classifications as described above should not prepare fully contained spring exemption reports.
1) Summary Determination
The report must include a summary of the qualified professional’s determination, using the information listed below as evidence to support the conclusion that the spring meets the fully contained spring requirements listed in Attachment A, Section 3 of the Cannabis Cultivation Policy. Specifically, the report must clearly state that in the author’s professional opinion the spring does not have the potential to flow off the property (parcel boundary) or into a channel that flows off the property by surface or subsurface means in the absence of diversion. Unsupported determinations will not be approved.
2) Site Description
The report must include a detailed description and photographs of the spring.
- Photographs must be captioned and identify what is shown, with labels added as needed. At a minimum, the report must include photographs of all of the following, to the extent physically feasible: detailed image of spring orifice; diversion works; diversion overflow; image of spring orifice from a reasonable distance both up and down gradient for context; overview of spring orifice looking towards nearest downgradient feature, such as a property line, surface water channel, or water body. The report must include any additional photographs that provide context for the spring, such as landscape position/setting, and to the extent possible, photographs of all features discussed in the text of the report. The report must include the location and direction/perspective of each photograph on a site figure or map and reference the photograph exhibit number used in the report.
- The site description must include a labeled schematic, map, or drawing of the entire diversion system, including: spring orifice, point of diversion, conveyance (e.g. piping, ditch), storage (e.g. pond, reservoir, tanks, bladders), overflow, water meters, place(s) of use, point(s) of rediversion (e.g. sump, transfer pump). The schematic must clearly depict the diversion system such that it can be understood in the context of the report, using reference photographs, maps, or sections of the report, as needed.
