Abstract
The purpose of this study was to establish a more efficient monitoring program for the San Pedro Riparian National Conservation Area (SPRNCA). This report analyzes data on stream flow measurements taken at nine locations on the San Pedro river and one location on the Babocomari river and ground water levels in eighteen wells collected by the BLM over the period from 1987 to 1995 and discusses possible causes for trends and anomalies in the data. The report also recommends future data collection and analytical efforts. All of the stream discharge data and some of the groundwater levels were collected at discrete and unsystematic intervals, and further, the streamflow measurements may not have been collected at the same location at each site. Surface water flow was measured by a Marsh- McBirney flow meter.

The investigation described in this report was performed with the financial support of the U. S. Bureau of Land Management (BLM). The findings and conclusions presented in this report are those of the authors, and do not necessarily reflect the positions of the BLM. The authors are indebted to the staff at the Bureau of Land Management office in Sierra Vista, and in particular to Ben Lomeli who spent a considerable amount of time in assembling the data that had been collected in the San Pedro Riparian National Conservation Area. Thanks are also due to Christopher Smith of the Arizona District Office of the U. S. Geological Survey for assistance with retrieving the USGS flow data for the Charleston stream gage. We also greatly appreciate the review comments provided by Howard F. McCormack of the U. S. Geological Survey.
