Predevelopment Hydrology of the Salt River Indian Reservation, East Salt River Valley, Arizona

摘要

The purpose of the report is to describe the hydrologic conditions that existed in the area of the Salt River Indian Reservation prior to development by non-Indian settlers. Non-Indian settlers were diverting significant quantities of water from the Salt River near the reservation in the 1870's. Hydrologic data do not exist for the period prior to 1870; therefore, data collected since 1870 were used to evaluate predevelopment conditions, as described in the section entitled 'Approach'. The results of the evaluation represent long-term average hydrologic conditions.
