The purpose of this study is to determine the hydrologic and hydraulic impacts of the Aspen Fire of the summer of 2003 on the Sabino Canyon and Carter Canyon watersheds, which are in the vicinity of the Town of Summerhaven, located on Mount Lemmon in the Santa Catalina Mountains, Arizona.

The purpose of this study is to develop a physical, process-based hydrologic model for the Finger Rock Wash watershed. A HEC-1 model was developed to estimate the 100-year discharge rate.

Purpose of this report is to provide a detailed analysis of the runoff characteristics of the Diamond Bell Ranch area.To this end, HEC-HMS models were generated to analyze the runoff under existing watershed conditions.
