Groundwater Quantity Management Program

Rules & Regulations: Groundwater Use in Fully & Over Appropriated Areas

Central Platte NRD’s Groundwater Management Quantity goal is to assure an adequate supply of water for feasible and beneficial uses through proper management, conservation, development and utilization of the District’s water resources. CPNRD is involved in groundwater level observations, administering irrigation runoff regulations, groundwater quantity and quality management, groundwater modeling and development of a surface water flow model which will all lead to a complete groundwater and surface water management program. Groundwater Management programs offered as a service to landowners/operators include: Water Well Registration Verification Program, Water Well Permits, Decommissioned Well Program and Instream Flow Water Rights.  2015 Annual Water Use Summary

Nebraska leads the nation in irrigation production with over 8 million irrigated acres. Being in the Platte River Watershed, the District’s primary surface water feature is the Platte River. However, most farmers rely on groundwater for their irrigation needs since groundwater is abundantly available across the District. Water supply is under continuous monitoring throughout the District and a groundwater supply management plan to address potential shortages has been adopted by the NRD’s board of directors and has been in effect since 1987. Groundwater aquifer declines have been documented where irrigation use is the heaviest.

Groundwater is the District’s chief source of drinking water and primary economic resource of the NRD since we depend on it for irrigation; which, in turn, enables us to have a strong economy rooted in agriculture. If there was any doubt that we need to take care of this resource, it should’ve been dispelled by declining water tables in the late 1970s & early 1980s. Rainfall increased in the mid-1980s/1990s, which caused water tables to rise, but the historic record suggests complete groundwater recovery from the dry periods during the wet periods does not always occur in all areas. Careful management of the resource is necessary. Aquifer thickness varies from 25-300+ feet across the district, so a drop of one foot has a more significant impact on some parts of the District than on others.

Groundwater depths and thicknesses are charted and used to help establish 24 groundwater supply management areas. Besides the aquifer conditions, the soils and topographic characteristics are similar in each management area. The 1982 groundwater levels were established as the standard for the management plan since rainfall and recharge were above av- erage several years since 1982. The maximum acceptable decline for each of the management areas was calculated, establishing a margin of safety in each area. It was determined that as an area’s average groundwater level declined through that margin of safety, certain controls ought to be mandated to slow the decline.

In 1987, the board established the Groundwater Management Plan with a phased program to implement controls when needed. The maximum acceptable decline ranges from 10’ in the eastern end of the District to 30’ in portions of the western end of the district. If the water table falls to 50% of that maximum decline (5 and 15 feet respectively for each of the range parameters), Phase II would go into effect for any area or areas affected, triggering mandatory reductions in irrigated acres and establishing spacing limits for new irrigation wells. Further declines to 70%, 90% & 100% of the maximum acceptable decline will trigger Phase III, IV and V controls respectively, mandating additional cutbacks in irrigated acreage and increased spacing limits for new wells. Complete details of the controls are available in district publications. Because of the differences in the aquifer depth and conditions, it is conceivable that some areas could be in the higher phases while other areas may always be in Phase I.

Groundwater Levels

CPNRD staff measures 600 wells, twice a year, in conjunction with the Conservation & Survey Division, UNL and the US Geological Survey. The measurements are taken in all 11 counties served by the NRD to monitor the District’s groundwater levels. The groundwater levels of 1982 are used by the district as the benchmark year to compare groundwater level changes. This was established as part of the 1987 Groundwater Management Plan. That plan established 24 sub-districts across the NRD for monitoring groundwater level changes see Figure 13 below.

Platte River Recovery Implementation Program

CPNRD participates in the Platte River Recovery Implementation Program (PRRIP) with the states of Nebraska, Colorado, Wyoming and the Department of Interior to find a solution for endangered species in the Central Platte Basin; as well as water rights for the landowners/operators in the District.  PRRIP was developed by the federal government along with the basin states of Nebraska, Colorado and Wyoming and signed in 2006. Local, state and federal government agencies are working with groups from throughout the basin to build a framework for a long-term Program that will satisfy Endangered Species Act (ESA) requirements for water users in the basin.  The first PRRIP increment, planned to last 13 years, includes completion of water projects expected to improve flows in the central Platte by an average of 130,000-150,000 ac/ft annually.  A second Program element is the protection and maintenance of 10,000 acres of habitat during the first increment, ultimately working toward a 29,000-acre goal. The specifics of subsequent increments will be planned as more information is developed. Through an adaptive management process, the Program goals may be modified as appropriate.

CPNRD has a big stake in the Program’s goal to improve and conserve habitat for three threatened and endangered species on the central Platte (the whooping crane, piping plover and least tern) and the endangered pallid sturgeon on the lower Platte. The Program was developed as the states and federal governments face stiff challenges to protect threatened and endangered species using the Platte River and their habitats.  The signatories to the Program hope to equitably provide greater certainty for water users facing ESA requirements. The U.S. FWS plays a major role in enforcing the ESA. Authorization legislation for federal funding was passed by Congress in 2008 and associated appropriations will be addressed in an ongoing process.  District board members, management, and staff are actively involved in Program Governance and Advisory committees.

The Program is starting to develop a plan for the review of the U.S. FWS’s target flows for the Platte River.  Ongoing research and monitoring on the Platte is showing the Service’s current target flows to be ineffective in accomplishing the objectives they have set out.  The Program’s Land Advisory Committee includes a member/alternate from CPNRD, member/alternate from Tri-Basin NRD, and a joint member/alternate.  The Program’s Water Action Committee is looking at intentional groundwater recharge through diversions through the canal systems.  One of the projects that was done in fall and winter 2011, was to study recharge in the Phelps Canal, one of CNPPID canals just below the J-2 Return.  In 2013, the Program’s Governance Committee (GC) and CNPPID independently agreed to fund and develop the J2 Regulating Reservoirs at a cost of $13 million for five years.

In September 2015, CNPPID and its engineering contractor, RJH Consultants, Inc., provided the GC with a progress report on development of the J2 Reservoirs Project which detailed significant increases in cost from the original estimate of $63 -$170 million, not including land acquisition.  The GC authorized the Program’s Executive Director to work with CNPPID and NDNR to evaluate J2 Project alternatives that can be accomplished within the available budget.  Central Platte, Twin Platte and Tri-Basin NRDs each purchased a percentage of the Nebraska share. CPNRD purchased 20% of the State’s share (2,040 ac-ft annually) for just over $1.5 million.  In July of 2016, the GC directed the project be put on hold until further notice while the PRRIP pursues other water project opportunities involving groundwater recharge, smaller scale storage projects, and water acquisition and transfer opportunities.

In 2016, a contract with CPNRD and Aqua Geo Frameworks LLC was approved by the board for aerial electro-magnetic survey work.  The survey work includes additional coverage of flight lines to cover various project areas at a Program cost of $64,000.  Program Extension: In November 2016, the GC approved summary language for a Program First Increment Extension, contingent on approval of a budget.  The new proposed budget funding focuses on aggressively moving forward on water projects ($12.7 million out of a total budget of $19.1 million) and includes some significant reductions in select monitoring and research components.  The 13-year extension (post 2019) lays out what the Program would strive to accomplish, with a focus on pursuing water milestones. While milestones for land and adaptive management components have been met and exceeded, water goals have been tougher and more expensive to achieve.  Initial discussions included prioritizing resolution of channel choke point issues, additional habitat acquisitions, and investigating opportunities to support pallid sturgeon use of the lower Platte River.The GC also approved an amendment to the Water Service Agreement for the J2 Reservoir Project.  The Project has formally been placed on hold while the parties involved evaluate how best to proceed.

Groundwater Exchange Program

The Groundwater Exchange Rules & Regulations was updated in September 2016 to expand the Program to include the Loup Basin within the District and add definition of terms.  The second Groundwater Exchange began on October 3rd.  The CPNRD board of directors approved expanding the Groundwater Exchange to include the Loup Basin within the District and to add definition of terms to their Rules & Regulations at their September board meeting.  Plan With Changes

The Groundwater Exchange pre-approval process for buyers and sellers to meet with CPNRD staff will take place through November 23rd, so that producers will have time to plan for spring planting. During the pre-approval process, staff will verify that all participants are in compliance with the NRD’s Rules and Regulations, document whether the participant is acting as a buyer or seller, the location and amount of water use, and whether the buyers want to purchase water for irrigation or for streamflow.  The online bid window for those pre-approved will be open from December 1 through December 9, 2016.  Buyers and sellers will go online to the CPNRD Exchange website with the personal ID that staff has provided to them.  Sellers will enter the amount that they would like to receive for their water use, and buyers will enter how much they are willing to pay.
