MonitoringLocationDescriptionText The sample site is USGS streamflowgaging station (09403013) in the Garden Creek basin that monitors discharge from Pumphouse Spring (Two Trees Spring). The station is about 40 m northeast and 8 m up the slope from the NPS Indian Gardens pump station and approximately 100 m down the slope from Pumphouse Spring in a small stream channel developed in hillslope alluvium that overlies the Bright Angel Shale. Downstream from the gaging station, water flows continuously in a small channel for about 30 m and then enters Garden Creek, which flows continuously to the Colorado River. The site is in the Bright Angel Fault zone. Water samples were collected from the small pool of flowing water at the streamflowgaging station, and discharge was measured with a Parshall flume. The sample site is within the boundary of Grand Canyon National Park.
