Results of Ecosystem Scale Selenium Modeling in Support of Site-Specific Guidelines Development for Lake Koocanusa, Montana, U.S.A., and British Columbia, Canada, 2020

Metadata Updated: October 29, 2023

This data release and accompanying spreadsheet illustrate the ecosystem scale selenium model for Lake Koocanusa described in USGS Open-File Report 2020-xxxx, "Understanding and Documenting the Scientific Basis of Selenium Ecological Protection in Support of Site-Specific Guidelines Development for Lake Koocanusa, Montana, U.S.A., and British Columbia, Canada." All report sections, equations, and tables referenced in this data release and spreadsheet are from that report, referred to hereafter as “the OFR.” Two models are described in the OFR. Results for several different “runs” of this model with different model input parameters and assumptions are included in this data release. The spreadsheet calculations that produced those results are also included with this data release. Model 1, IFM = Insect-to-fish model, summarized by Eq. 11: protective C(Se)dissolved = tissue guideline/TTFfish /[(TTFinvert1invert fraction1) + (TTFinvert2invert fraction2)]/SPM bioavailability fraction/(Kd/1,000). Model2, TFM = Trophic-fish model, summarized by Eq. 12: protective C(Se)dissolved = tissue guideline/TTFfishTL4/TTFfishTL3/[(TTFinvert1invert fraction1) + (TTFinvert2invert fraction2)]/SPM bioavailability fraction/(Kd/1,000). Model results are presented for the four representative IFM food webs described in Table 6 of the OFR, and for three representative TFM food webs described in Table 7 of the OFR. “Generic” IFM and TMF modeling spreadsheets (consistent with Tables 8 and 9 of the OFR) are provided that implement the two models such that a user can establish their own modeling assumptions and view the results of the models with those assumptions.Finally, four alternative modeling scenarios and results specifically requested by the Montana Department of Environmental Quality, the cooperator in this work, are also presented here.
