Issue: There is uncertainty about groundwater recharge in the Silvies, Donner und Blitzen, and Silver Creek floodplains.
7
An evaluation of the floodplain characteristics that affect recharge (soil type, depth, location, etc.) would provide information that could be used to optimize recharge during flood irrigation application.Seek funding for a scientific study of groundwater rechargeHCWC; HDP1-2 yrs.$250,000OWEB; USGSAn understanding of the locations and rates of recharge across the floodplain so that recharge can be effectively managed.Identification of potential areas to flood to maximize rechargeEvaluation of legal methods for increasing recharge
8
Issue: There are concerns that groundwater withdrawal has an adverse effect on surface water as expressed by declining or halted spring flow, declining stream flow, andpossibly lake level effects.
9
Strategies to reduce groundwater pumping should be targeted to pumping areas affecting springs, streams and lakes. The Harney Valley Groundwater CREP incentives reducing pumping affecting groundwater dependent ecosystems.Increase monitoring of spring flowsMNWR1-2 yrs.?OWRDdata on changes in spring and river base flow Implementation of the CREP program should be monitored to evaluate the effectiveness of the proposed incentive structure.baseflow measurement and spring discharge
