Over
more than a decade, Ebert & Associates has, largely in the context of
studies carried out for the Department of Justice and the Bureau of Indian
Affairs, developed methods which integrate data from historic aerial photointerpretation,
historic maps, informant interviews, and fieldwork to discover, characterize,
and quantify evidence of historic and prehistoric agricultural water use.
Variations through time in historic irrigation can be quantified, and
given adequate aerial photographic coverage through time, priority dates
established in some cases. Of course, evidence of prehistoric agricultural
water use that can be supportably associated with current property owners
provides the earliest priority dates. |
