Reconnaissance Survey of Specific Conductance along the Tongue River between the Streamflow-Gaging Stations at Monarch, Wyoming, and State Line, Montana, September 27-28, 2005

Specific conductance of the Tongue River typically increases between the U.S. Geological Survey streamflow-gaging stations at Monarch, Wyoming (06299980), and State line, Montana (06306300). However, the locations of the inflows contributing the dissolved minerals that increase the specific conductance of the Tongue River are not known. A reconnaissance survey of specific conductance was conducted September 27-28, 2005, to determine where specific conductance increases through this reach. Specific conductance was measured at 23 sites along the mainstem of the Tongue River and at 21 inflows (fig. 1).

 

Measurements on September 27 began downstream from the bridge at Montana Highway 314 at 0941 hours and were completed at 1830 hours at the State line gage. Measurements on September 28 began at the Monarch gage at 0830 hours and were completed at 1130 hours upstream from the bridge at Montana Highway 314 (fig. 2; table 1). Measured inflows (table 2) included tributaries, an irrigation return flow, and permitted discharges from coalbed methane production facilities. Water-quality samples were collected for laboratory analysis from selected inflows. Sodium adsorption ratios for these samples are listed in table 2; other analytical data for these samples is available at http://nwis.waterdata.usgs.gov/usa/nwis/qw.
