Water-Quality Monitoring and Modeling of the Keno Reach of the Klamath River

Klamath Straits Drain
Klamath River, Link River to Keno Dam
Models of the Klamath River from Link River to Keno Dam were constructed and calibrated by the U.S. Geological Survey for calendar years 2006-09. These models support the analysis and results that are documented in the project reports. The latest version of the model is documented in the following report:
Sullivan, A.B., Rounds, S.A., Asbill-Case, J.R.,
and Deas, M.L., 2013, Macrophyte and pH buffering updates to the Klamath
River water-quality model upstream of Keno Dam, Oregon: U.S. Geological
Survey Scientific Investigations Report 2013-5016, 52 p.
The most recent models used in this study included small changes to a few boundary conditions. Those models are the ones used to run a set of model scenarios, as documented in:
Sullivan, A.B., Sogutlugil, I.E., Rounds, S.A.,
and Deas, M.L., 2013, Modeling the water-quality effects of changes to
the Klamath River upstream of Keno Dam, Oregon: U.S. Geological Survey
Scientific Investigations Report 2013-5135, 60 p.
These Link River to Keno Dam models are available for download at the links below. These models are based on the November 2010 release of version 3.6 of the CE-QUAL-W2 model.
Klamath River, Link-to-Keno Drawdown
Model scenarios for a hypothetical drawdown of the Link-to-Keno reach are documented in a report published in 2020:
Sullivan, A.B. and Rounds, S.A., 2020, Modeling a
2- and 4-foot drawdown in the Link River to Keno Dam reach of the Upper
Klamath River, south-central Oregon: U.S. Geological Survey Scientific
Investigations Report 2020-5001, 18 p.
These Keno-drawdown models are available for download at the links below. These models are based on the November 2010 release of version 3.6 of the CE-QUAL-W2 model.
Models of Link River from Link Dam on the outlet of Upper Klamath Lake to the start of the Klamath River were documented in a 2016 report:
Sullivan, A.B., and Rounds, S.A., 2016, Modeling
water quality, temperature, and flow in Link River, south-central Oregon:
U.S. Geological Survey Open-File Report 2016-1146, 31 p.
The Link River to Keno Dam models developed and used in the updated calibration report (see https://pubs.usgs.gov/sir/2013/5016/) are available for download at the links below.
For the sake of documenting the Link River to Keno Dam models used for the original calibration from 2011 (see https://pubs.usgs.gov/sir/2011/5105/), those models also are available for download at the links below. Note, however, that these older models have been superseded by the ones above, and the pH results from the older models are not considered to be calibrated.
Animations of model output from year 2007 were created to help visualize the patterns, dynamics, and characteristics of selected water-quality parameters. The animations show a longitudinal slice along the downstream axis of the Klamath River from Link River (at the far right) to Keno Dam (at the far left), where colors in the animation illustrate temperatures or concentrations according to a color scale at the upper right. The animations are available for download here:
If you don't have a movie player that allows fine control over frame advancement and reverse, you might consider obtaining one. For the Mac and Windows environments, you might try the free QuickTime viewer from Apple. For Unix systems, one option is the free xanim viewer.
The model executable included in the model packages above (w2_generic_b.exe) was compiled from the November 2010 Release of the version 3.6 CE-QUAL-W2 generic source code using the following Intel Visual Fortran compiler options. These options are the ones recommended in the CE-QUAL-W2 manual with the addition of the /fp:precise switch to force consistency in floating-point calculations.
For most modules, the following compiler options were used:
/nologo /O3 /Og /Qparallel /real_size:64 /module:"Release\\" /object:"Release\\" /libs:static /threads /winapp /fp:precise /cFor only the TEMPERATURE, TRANSPORT, and WQCONSTITUENTS subroutines:
/nologo /O3 /Og /Qparallel /real_size:64 /module:"Release\\" /object:"Release\\" /libs:static /threads /winapp /fp:precise /c /QopenmpFor only the WATER-QUALITY subroutine:
/nologo /Og /Qparallel /real_size:64 /module:"Release\\" /object:"Release\\" /libs:static /threads /winapp /fp:precise /cNote that the library file libiomp5md.dll must be kept in the same folder as the executable.
