phased approach has been used for addressing the various concerns
expressed by agencies of Federal, State, and local government, concerned
citizens, and other groups.
One -- October 1994 - September 1998
this phase, the focus was on (1) defining the extent of aquifers,
(2) defining ground-water conditions, (3) refining basin water budgets,
and (4) quantifying ground-water use. Phase one publications included
Plume, R.W., and Ponce, D.A., 1999, Hydrogeologic framework and
ground-water levels, 1982 and 1996, Middle Humboldt River Basin,
north-central Nevada: U.S. Geological Survey Water-Resources Investigations
Report 98-4209, 2 map sheets.

and Upper Reese River Valley Hydrographic Areas, Middle Humboldt
River Basin, North-Central Nevada--Methods for Estimation and Results:

Two -- October 1998 - September 2003
focus of this phase is on developing a computer model that links
ground-water flow with surface-water flow in the middle Humboldt
River Basin. The utility of such a model will be that the effects
of man can be evaluated separately from the effects of climate variability.
At present (2002), several studies necessary for constructing the
model are underway. These studies are (1) Statistical analysis of
historic streamflow records for the Humboldt River, (2) Construction
of a surface-water routing model for the middle Humboldt River,
(3) Construction of a ground-water flow model, and (4) Construction
of rainfall-runoff models for selected basins. Each of these individual
studies is necessary for construction of the linked model. The following
publications are currently in progress:
