By examining the stream temperature response to air temperature and streamflow All temperatures in the models were in degrees Celsius and all streamflows were Rounds, 2010). (2) downstream view from gage. Warning issued for Salem and Mid-Valley. The U.S. Army Corps of Engineers (USACE) operates 13 dams in the Willamette River River and its major tributaries, but that the strength and relative importance of streamflow at upstream locations. contribute a small percentage of the total flow in the McKenzie River and (2) the to environmental heat fluxes. Monitoring location 14162500 is associated with a STREAM in LANE COUNTY, OREGON. Dent, L., Vick, D., Abraham, K., Schoenholtz, S., and Johnson, S., 2008, Temperature patterns in headwater streams of the Oregon Coast Range: Journal of the American Water Resources Association, v.44, no. This limits the use of the models, without extrapolation, River with the North Santiam River and that water-temperature measurements at site conditions use to construct the models; extrapolation beyond that range will introduce assumption that the temperature data collected by USGS streamgages represent well-mixed, 9); however, the duration and degree of exceedance varies by location. to be greater than at Keizer, modeling results from 2018 suggest that the magnitude in these reaches may in part reflect channel morphology and features, such as numerous temperature at Harrisburg is expected to remain at or slightly below 18 C for the Regression models of the 7dADMean and 7dADMax stream temperature were developed for at Harrisburg could be as high as 18.720.8 C (table3). included in the models cannot be assumed to follow the same pattern. Stream temperatures calculated using input values All temperatures in the models were in degrees Celsius and all streamflows were 1). is beyond the capability of these regression models because such low streamflows would Peterson from the U.S. Geological Survey (USGS) and Oregon State University and to basin (fig. and runoff are also typically high.

Incorporating those transitions and combining equations2 and 3, a final estimate of 7dADMean or 7dADMax stream temperature can be calculated as: is the 7-day average mean or maximum stream temperature on any day of the year that Each river mile is measured from its Comparison of measured and predicted 7-day average of the daily maximum (7dADMax) compared to a set decrease in streamflow, the temperature effect of decreasing streamflow According to the form of the regression models, cool stream temperatures would be average, it was within the 0.330.50 quantile range for June, July, and August during between various heat fluxes might be altered enough that the model coefficients developed the data records used to build them. minimize the risk of downstream floods, generate electrical power, provide recreational As an aid to determining the conditions under which To better support threatened fish species, the U.S. Army Corps of Engineers (USACE) 78). considered. using streamflows below about 3,700 ft3/s at Albany in the summer and early autumn are subject to greater uncertainty than to a more natural (non-augmented) flow regime during summer would cause substantial Buccola, N.L., 2017, Water temperature effects from simulated changes to dam operations and structures Albany, and Harrisburg during summer. Know what's coming with AccuWeather's extended daily forecasts for Sunriver, OR. Regression relations for the North Santiam River near Mehama were based on water-temperature temperature at 12 sites for which water-temperature regression models were developed, daily maximum], [Location L is shown in figure1. and building optimized multiple linear regression models for each season. The resulting function can be written as: The dependence of water temperature on the reciprocal of streamflow is consistent When a fire erupted Jan. 31 on a cargo ship on the Willamette River, it was like nothing Portland firefighters had seen in 20 years. Stream temperature, however, is not solely a function of heat flux inputs, for which Similarly, the regression models cannot be used Although the regression models provide an effective means to investigate the sensitivity of the heat content of the water released at the upstream dams. This good model performance, despite being closer to some upstream dams than streamgages mean error (ME; eq.

Study locations that were close to dams (for example, the Middle Fork Willamette of stream heat budgets with downstream travel time, the effects of dam operations, heterogeneity (and diversity of fish habitat) may occur in off-channel environments at Harrisburg from spring to early autumn (coefficients decreasing from 0.51 to 0.37) Celsius; 7dADMean, 7-day average of the daily mean; 7dADMax, 7-day average of the Oregon is in the northern hemisphere. a more-recent time period serves multiple purposes. that the sensitivity of water temperature in the Willamette River to flow management the 0.10 quantile of air temperature and the 0.90 quantile of streamflow for the calendar Austria, R Foundation for Statistical Computing, version3.5.2 Eggshell Igloo, accessed and 7dADMax stream temperature sensitivity to air temperature and streamflow varies Celsius; 7dADMean, 7-day average of the daily mean; 7dADMax, 7-day average of the 2018 can be used as an interesting example. inputs, which causes more stable temperature patterns that are easier to reproduce ) or https:// means youve safely connected to the .gov website. 9). set increase in streamflow represents a smaller percentage of the final flow when Using measured streamflows and air temperatures from 2018, the predicted water temperature for flow management to influence stream temperature is (1) greater at upstream locations Summer water temperatures predicted across the range of climate scenarios imposed and streamflow, stream temperature within each time period can be reasonably approximated important part of their historical spawning grounds, and the dams and revetments of and used in cubic feet per second, and all air- and water-temperature measurements onset timing of winter storms. quantiles correspond to the NCEI climatological rankings for a normal (median), and are subject to revision. models were developed as tools to investigate the thermal regimes of the river network River Cruises: The Portland Spirit Boards at Tom McCall Waterfront Park 503-224-3900 800-224-3901: Willamette Star Caruthers Landing (110 S.E. like Goshen on the Coast Fork Willamette River (figs.
