Water quality analyses of the recreational waters of Sabino and Bear Creeks

Abstract

Sabino Canyon Recreation Area has received over 600,000 visitors per year. Sabino and Bear Creeks flow through the area creating a diverse habitat for vegetation and wildlife, and a unique desert setting for water-based recreation. Proximity to the city of Tucson places constant user pressure on the water resources and prime concern in a water-based recreation area is water quality. An intensive study of existing water quality status of Sabino and Bear Creeks was conducted because the quality of water in Sabino and Bear Creeks was unknown. This study examines bacterial, chemical, and physical parameters. Data were collected twice a week on Sundays and Wednesdays for a year. Results of the study indicate there were: (1) no major chemical problems, (2) highest turbidity values occurred during the warm weather months, and (3) high concentrations of fecal coliform in the bottom sediment and periodically in overlying water indicate major sources of fecal contamination have access into Sabino Creek. This study provides the United States Forest Service with baseline water quality data and a benchmark from which to continue an efficient water quality monitoring program.
