Groundwater Simulation and Management Models for the Upper Klamath Basin, Oregon and California

Table 2. Transient stream-flux observation locations used in calibration of the upper Klamath Basin, Oregon and California, regional groundwater flow model.

[Abbreviations: USFS, U.S. Forest Service; USGS, U.S. Geological Survey; mi, mile; RM, river mile]

Observation name Stream(s) Source of groundwater discharge (baseflow) estimate
BON Lost River near Bonanza Spring. Six spring discharge estimates made from synoptic streamflow measurements.
SPR Upper Sprague River—Headwaters to the gage near Beatty. September mean flows at the USGS gage near Beatty, 1969–2004.
UWIL Upper Williamson River—Entire drainage above the gage near Sheep Creek (RM 67.7). September mean flows at the Oregon Water Resources Department gage below Sheep Creek, 1974–2003.
LWIL Lower Williamson River—Williamson River between the gage near Klamath Agency (the Kirk gage) and the gage below the Sprague River; the Sprague River below the gage near Chiloquin, and Spring Creek. Monthly estimates of groundwater inflow based on differences in flow at stream gages on the Williamson near the Klamath Agency and below the Sprague River, and on the Sprague River near Chiloquin, 1969–2004.
SAND Sand Creek—Entire drainage above RM 5.8. September mean flows at RM 5.8 (data from USFS gage about 
4.5 mi west of U.S. Highway 97), 1993–2002.
WOOD Wood River headwaters springs. 122 instantaneous measurements made at Dixon Road.
SEV Sevenmile Creek—Entire drainage above 
RM 17. September mean flows at RM 17 (data from USFS gage about 1 mi north of USFS Road 3300), 1993–2002.
CHER Cherry Creek—Entire drainage above Westside Road. September mean flows (data from USFS gage about 0.5 mi west of Westside Road) 1993–2002.
KLAM Klamath River between Keno and the gage below J.C. Boyle Powerplant. August accretions based on USGS gages at Keno and below J.C. Boyle Powerplant, and reservoir content data from PacifiCorp.
SPEN Spencer Creek—Entire drainage. September mean flows from USFS gage about 1 mi below Buck Lake, 1993–98.
