(GRAND ISLAND, NE)- The Central Platte Natural Resources District (CPNRD) announced today that it will receive $364,900 from the Nebraska Environmental Trust for the “Advanced Hydrogeologic Frameworks for Aquifer Management in Critical Sections of the Platte River Basin” project.
Duane Woodward, CPNRD engineering hydrologist, said that water management in the Platte and Republican River basins continues to be a difficult task for water managers and users alike. The recent drought conditions and management needs within the Twin Platte and Central Platte Natural Resources Districts (NRDs) require new information and understanding of the natural system for determining the proper course for utilization of infrastructure and revenue.
Woodward said that “the NRDs need detailed information of the aquifer conditions and the subsurface hydrogeologic framework to effectively design and apply integrated management plans.”
In particular, the NRDs need to understand the aquifer geometry, characteristics, inter-connection with surface water, impacts of new and existing infrastructure and interaction with adjacent aquifers. Currently, NRDs rely on the traditional method of geologic test hole drilling for information regarding the subsurface geology; which is vital to the understanding of the area but alone cannot provide enough spatially distributed information to complete a detailed hydrogeologic framework of a NRDs aquifer resources.
Often, these test holes are spaced on 6 mile centers, a distance that does not provide the detail to be useful in developing a local hydrogeologic framework. Funding for the Airborne Electromagnetic Mapping (AEM) allows new infrastructure and future sub-regional groundwater model investigations to be developed for evaluation of the proposed management practices.
A total of $296,000 (30%) in matching funds will be provided by the NRDs and Exploration Resources International in the form of cash and/or in-kind services for aerial collection and subsequent data interpretation, databases, map production, data reports and improvements to the AEM process.
The Trust Board announced funding for the project at its meeting on April 6, 2017 in Lincoln. This is the second and final year of award. The project is one of the 85 projects receiving $16,680,000 in grant awards from the Nebraska Environmental Trust this year. Of these, 33 were new applications and 52 are carry-over projects.
