Reply to [“Comment on “Testing the interbasin flow hypothesis at Death Valley, California’”] Winograd et al.



We happily respond to Winograd et al. regarding our recent Eos article concerning interbasin flow [Nelson et al., 2004]. We reiterate that we specifically reject interbasin flow only to Death Valley (DV) from Ash Meadows (AM) through the southern Funeral Mountains (FM), but suggest it should be critically reexamined elsewhere. Clearly, fractured carbonate rocks may be transmissive and deliver much water to a well or spring. We question, however, the spatial scales over which interbasin flow has been invoked, involving as it must continuously connected fracture permeability over tens to hundreds of kilometers.
