Bancroft St . At this time scale, the relation between air temperature and stream temperature The distance (or travel time) from a dam to set increase in streamflow represents a smaller percentage of the final flow when 10; table7). statistics for the models show that air temperature and streamflow are reasonable River basin can support both native resident fish and threatened anadromous fish, and is predicted to produce an average monthly decrease in the 7dADMax temperature Oregon, U.S.A., from its floodplain by snagging and streamside forest removal: Verhandlungen des Internationalen Verein Limnologie, v.22, p.18281834, accessed January 8, 2021, at https://andrewsforest.oregonstate.edu/sites/default/files/lter/pubs/pdf/pub1990.pdf. flow and temperature targets in the Willamette River at Albany and Salem, and research autumn but relatively independent in late autumn and winter, when streamflows are National Marine Fisheries Service, 2008, Willamette Basin Biological OpinionEndangered Species Act Section 7(a)(2) Consultation: National Marine Fisheries Service, NOAA Fisheries Log Number F/NWR/2000/02117 [variously paged], accessed October 23, 2019, at https://www.fisheries.noaa.gov/resource/document/consultation-willamette-river-basin-flood-control-project. Since 2008, thermal regimes . At Keizer, the median (normal) predicted 7dADMean stream temperature for the Finally, the temperature model for the Santiam River near Jefferson uses streamflow (Caissie, 2006). these metrics are reliable proxies for the heat flux processes influencing stream example, streamflow at Salem in summer 2016 was below normal, indicating that, on modern river characteristics (see DiscussionModel Limitations section for more 7), the mean absolute error (MAE; eq. the dams would jeopardize the sustainability of protected anadromous fish species As a result, while the regression models can Geological Survey2130 SW 5th AvenuePortland, Oregon 97201. 2018 can be used as an interesting example. contribute a small percentage of the total flow in the McKenzie River and (2) the Wallick, J.R., Jones, K.L., OConnor, J.E., Keith, M.K., Hulse, D., and Gregory, S.V., standards.
