Additional water returned to the Platte River via the <br />North Dry Creek cutoff or the Lost Creek/Ft. Kearny cutoff flows through roughly 60 <br />percent of the critical habitat. <br />Impacts on return flows or Platte River flows should be minimal if the implementation of <br />a groundwater management program yielding 1,400 ac -ft/yr results in maintaining the <br />water table at a level that does not create problems for residents and farmers. <br />0 Legal and Institutional Requirements for Implementation: <br />Certain groundwater management options can be accomplished under current Nebraska <br />water law. For example, no permit would be required to convert to dry -land farming and <br />a permit would only be required for conversion to groundwater irrigation if the well used <br />for that purpose has not yet been constructed. For dry -land farming, CNPPID would seek <br />a modification from the Nebraska DWR to increase the EA by the same amount of <br />reduced storage use. For a conjunctive use project, an intentional recharge permit would <br />most likely be required to recharge the aquifer. Although legislation exists regarding <br />intentional recharge permits it is untested. If this project targets storage water for <br />recharge then the use of the storage right would need to be changed to include recharge. <br />A permit would also be required to pump back into the CNPPID's distribution system if <br />the well used for that purpose has not yet been constructed. <br />Actively pumping from high groundwater areas could face several legal obstacles. <br />Although current Nebraska water law would not require a permit from the Nebraska <br />DWR to actively pump groundwater into North Dry Creek or Lost Creek, there is <br />\\DN00\E- DRIVE\PROJECTS\Platte \Work Products \Task 94apc report (Version 7).doc 37 <br />
