Water Rights Assessment

McCurry Hydrology has undertaken the majority of its water resources projects in the western U.S., where water rights under the Prior Appropriation system plays a key role in determining where and when supplies are available.  Dr. McCurry has served as expert witness on cases in several states.  He developed a package for the USGS model MODFLOW that determines stream diversions according to the Prior Appropriation system under conditions of varying hydrology.

Dr. McCurry has completed water rights-related assessments including the following:

• Computing the timing and location of lagged stream depletions due to well pumping and lagged accretions due to irrigation return flows or recharge ponds
• Analyses of crop consumptive use
• Determinations of Tributary vs Non-tributary groundwater
• Estimates of canal leakage
• Evaluating changes in water use under varying water availability 
• Assessments of de minimus impacts and futile calls
• Providing Expert Reports, Depositions, and Expert Witness testimony
