The State Engineer held informational meetings on July 17 through July 20, 2017 regarding its Preliminary Draft Humboldt River Conjunctive Management Regulations. The State Engineer is proceeding through administrative rulemaking process to define how Humboldt River Decreed water rights and groundwater rights will be conjunctively managed. If you were unable to attend the informational meetings, you can view the power point used during these meetings by visiting http://water.nv.gov/HumboldtRiver/Humboldt_regs_Small_Business_July_2017.pdf.

As a brief history, the Humboldt River was adjudicated in the 1930’s and large scale groundwater development began approximately 20 years later. Existing studies support the assertion that groundwater pumping is depleting surface river flows. The groundwater basins surrounding the Humboldt River are over-appropriated as the amount of water withdrawals allotted by water rights exceed the perennial yield. As an alternative to curtailing water, the State Engineer is considering Conjunctive Management Regulations. The main objectives of these regulations are to maximize beneficial use of our limited water supply, allow for continued and uninterrupted groundwater use and provide mitigation to senior Decreed water right holders for conflicts of their delivery of surface water. These regulations aim to allow for replacement of injurious depletions to the senior surface right holders, and if replacement water is not available, to require groundwater users to participate in a basin-wide mitigation plan providing mitigation by financial compensation.

At this stage in the rule making process, the State Engineer is attempting to determine if the regulations are likely to place an economic burden on small businesses, and if so, to determine the extent of the impact. Small businesses can submit economic impact statements to the State Engineer for consideration. There are no current deadlines imposed by NDWR for submission of small business impact statements or comments to statements, however, it is likely that we will see some movement within as little as 30 days.

The Nevada State Engineer is working on a plan to define how to conjunctively manage Humboldt River Decreed water rights hydrologically connected with groundwater rights. This plan will take form through an administrative rulemaking process and will affect many water right holders in and around the Humboldt River Corridor. Nevada Farm Bureau is assisting the State Engineer in setting up informational meetings to discuss concepts in forming the regulatory plan and to obtain feedback on the plan’s economic impacts to small business, farms and ranches.

Currently the United States Geological Survey (“USGS”) and the Desert Research Institute (“DRI”) have a four-year study in the 34 groundwater basins that adjoin the Humboldt River Corridor. The results from the study will determine which individual groundwater wells are hydrologically connected to the surface water flows of the Humboldt River, and to what extent their connection impacts surface flows. Armed with this information, the Conjunctive Management Plan aims to apply annual financial assessments to be paid by each injurious groundwater well in an attempt to recompense senior surface water right owners for their loss of water.

The State Engineer’s preliminary draft regulations for conjunctive management identify the purpose of the regulations as a means to establish rules for a Mitigation Program for the Humboldt River and tributaries identified in the Humboldt River Decree and hydrologically connected groundwater. The plan will establish rules for mitigating conflicts through water replacement or other mitigation measures. The plan will identify water rights of use that are subject to or exempt from plan regulation. The draft regulations identify affected parties as any holder of water rights under the Humboldt River Decree, groundwater right holders whose pumping is determined to capture at least one percent of any Humboldt River Decreed water right, and mining projects whose mine pit lakes capture at least one percent of any decreed surface right and holders of storage water in Rye Patch Reservoir.

The preliminary draft regulations state that the percentage of capture will be initially determined by the USGS/DRI study and thereafter by any further study found suitable by the State Engineer. The State Engineer will determine the amount of conflict to each surface water right and the amount of injurious depletion by groundwater rights, measured in acre-feet, for use in establishing and enforcing the Mitigation Program. The Mitigation Program will be mandatory for all groundwater users determined to be injurious to senior surface water right users. Administration of the program will be funded through existing groundwater and surface water assessments, and the program itself will be funded by groundwater right holders or responsible parties of mining projects, based on their injurious depletions.

The preliminary draft regulations offer regulated groundwater users an alternative to the Mitigation Program by working with the State Engineer to obtain an approved water replacement plan or other type of mitigation plan. If a groundwater right holder fails to participate in the Mitigation Program or have an alternative mitigation plan approved by the State Engineer, that water right holder will be prohibited from diverting any groundwater until the injurious depletion is mitigated and may be subject to penalties and fines.
