National Water-Quality Assessment Program

By K.M. Beaulieu, J.P. Capesius, and J.B. Gebler


This report presents data from physical-habitat and geomorphic measurements that were made at 11 stream reaches in the Central Arizona Basins study area of the U.S. Geological Survey's National Water-Quality Assessment program from 1995 to 1998. Measurements of water velocity and depth, particle size of bed material, embeddedness of substrate, stream aspect, and solar contribution were made at each reach. In addition, the extent and type of dominant riparian vegetation along each reach were characterized. To maintain nationwide consistency, data-collection methods were based on protocols developed by the National Water-Quality Assessment program for the assessment of stream habitat.

Measurements were made at a single reach, designated as reach A, at nine sites (termed basic fixed sites) between October 1995 and January 1996. Measurements were made at three reaches, designated as reaches A, B, and C, at two of these sites (West Clear Creek near Camp Verde and San Pedro River near Charleston) between October and December 1996. In addition, measurements were made at three reaches at two other sites on the San Pedro River in December 1996. In October and November 1997, measurements were made at reach A of West Clear Creek near Camp Verde and reach A of the San Pedro River near Charleston. Cross sections and longitudinal profiles were surveyed on the nine basic fixed sites in late 1997 and in 1998.
