Water Sources in the Kofa Refuge

[SlowDave]

Does anyone have info on the mapped water sources in the Kofa Refuge?  I am planning on spending a week plus riding there in late Febuary or early March and the official map has numerous wells and tanks listed.  I am looking for info on which wells, tanks, etc actually have filterable water.  I called the refuge HQ and I was told that they are instructed to tell everyone they must bring their own water.

Thanks

Dave
