Station and Location Information: ► Latitude: 46.748932° North (WGS1984) ► Longitude: -121.808327° West (WGS1984) ► UTM Northing: 5177989 meters (NAD 1983 Zone 10N) ► UTM Easting: 591050 meters (NAD 1983 Zone 10N) ► Elevation: 2795.849 feet (852.175 meters) ► Recording Interval: 15 minutes Station Notes: ► We have installed an new rohn tower and are currently working on restoring in-water function to the site. All in-water equipment at this site is down, including Water Pressure, Water Temperature, Water Conductivity, Turbidity, and Stage. This message will be removed when the site is back running normally. ► The rain gage is unheated and will not accurately record in periods of ice or snow fall. ► This site records river stage only (not discharge). ► This station may experience problems during and after storm events due to extreme sediment load. Please use the gage height and discharge data with caution during these periods. Contact Information: This station is maintained by: Mount Rainier National Park, Geology and Imminent Threats Group. Funding for the construction and maintenance of this stream gage was provided by the following organizations:
