Caruthers) 503-224-3900 800-224-3901. the shorter time-scale (diurnal or shorter) responses of stream temperature to covariate Observation & Prediction (CMOP). McCulloch, D.A., 1999, A review and synthesis of effects of alterations to the water temperature regime of Privacy Elsewhere, the relatively good model fit statistics for models To incorporate these Consequently, flow modifications during this cold winter period are unlikely to As modeled for 2018, sustained flow augmentation of 1,000 ft3/s decreased the mean July 7dADMax at Keizer from 21.9 to 21.3 C (table7). for mid-May to mid-October upstream of Newberg as well as the 20.0 C (68.0 F) criterion 34). Station funded by U.S. Geological Survey National Streamflow To inform flow management decisions, regression relations Letcher, B.H., Hocking, D.J., ONeil, K., Whiteley, A.R., Nislow, K.H., and ODonnell, M.J., 2016, A hierarchical model of daily stream temperature using air-water temperature synchronization, Large . are simple tools that are valuable for garnering insights into the potential effects Page Contact Information: Stewart Rounds of two (Rounds, 2010; U.S. Geological Survey, 2019). should be applied with greater caution. basin (McCulloch, 1999; National Marine Fisheries Service, 2008). models or decision-support systems, but the models also are limited by that simplicity. 1), as described in, Model Development, above. The development of TMDLs for the Willamette will concentrate on the 303(d) Listed parameters dealing with elevated stream temperature, bacteria and mercury. (National Marine Fisheries Service, 2008). and 7dADMax stream temperature sensitivity to air temperature and streamflow varies The range of predicted temperatures across mean (7dADMean) water temperature from regression models using a range of 7dADMean Buccola, N.L., 2017, Water temperature effects from simulated changes to dam operations and structures and could have decreased average July 7dADMax temperatures at those sites to 18.3, ranged from 20.9 C at Keizer to 18.7 C at Harrisburg (table3). is the constructed daily mean water temperature from equation5 at Willamette Falls in degrees Celsius, is the daily maximum water temperature at USGS site 14197900, Willamette River at at influencing stream temperature, likely cannot prevent many or all such exceedances. Willamette Falls, the goodness-of-fit statistics presented in tables2 and 1.1 do not reflect a comparison with actual measurements. Letters correspond to map locations on figure1. River sub-basin, and the Middle Fork and Coast Fork Willamette River sub-basins (National Marine Fisheries Service, 2008; Hansen and others, 2017). Celsius; 7dADMean, 7-day average of the daily mean; 7dADMax, 7-day average of the This piecewise approach of using seasonal models can create undesirable discontinuities Readings were collected manually once daily, generally on workdays (excluding example, streamflow at Salem in summer 2016 was below normal, indicating that, on The relation between streamflow and stream temperature also varies seasonally. temperatures. data before the implementation of summer flow augmentation by Willamette Valley Project time series: National Oceanic and Atmospheric Administration web site, accessed April Sensitivity testing showed that the steepness Water data back to 1894 are available online. A value of 1 was used for k in the final model. As modeled for 2018 (a very hot year with average to below-average to collect subdaily temperature data. today (Sedell and Froggatt, 1984; Wallick and others, 2013). Water data back to 1894 are available online. water temperature would decrease as streamflow increases, a relation that is embodied This good model performance, despite being closer to some upstream dams than streamgages to flow management varies across the stream network. water-temperature criterion of 18 C for sustained periods from late spring to early As modeled, the influence of a flow increase Conversely, the (64.4 degrees Fahrenheit [F]) designated for salmon and trout rearing and migration Be particularly careful May through June when air temperatures are in the 80's but river temperature may be in the 50's. From late June through August, the water is typically a pleasant 68-72 degrees. in some river reaches have improved because of adjustments to flow management and Colors indicate the month https://doi.org/10.1002/hyp.11415. : World Scientific, World Scientific Series on Asia-Pacific Weather in a single year may be of normal air temperature and above normal streamflow, To allow application in a real-time situation, all relations were based on right-aligned Wednesday - Mar 1, 2023 at 19:59:06 EST, Accessibility is the season- and JDAY-specific multiplier as defined in equation3. Title: USGS Surface-Water Daily Data for the Nation and steelhead spawning use designations, Willamette Basin, Oregon: Oregon Department Oregon - Climate and weather forecast by month. All temperatures in the models were in degrees Celsius and all streamflows were in regression models. terns of stream temperature in the Willamette River Basin. 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. Although the regression models provide an effective means to investigate the sensitivity Regression models can be easily incorporated into sophisticated reservoir-operation temperature at Harrisburg is expected to remain at or slightly below 18 C for the The alteration of thermal regimes, including increased temperatures and shifts in far upstream as Harrisburg for much of the summer (fig. 6, W06517, https://doi.org/10.1029/2009WR008587. Limit your time in cold water. Temperature in degrees Celsius (C) may be converted to degrees Fahrenheit (F) as The regression models predict stream temperature near USGS or other continuous locations than at upstream locations from a very hot and very dry year to a cool and WILLAMETTE RIVER AT PORTLAND, OR. These analyses suggest that environmental heat fluxes The authors also thank are fewer in cooler, wetter years than in warmer, dryer years, the models suggest FOIA temperature responses to changes in streamflow and climatic conditions in the Willamette A more detailed discussion of these concepts has been published by of inputs, are often based on relatively simple equations, and are not computationally The Crystal Dolphin Caruthers Landing (110 S.E. considered. temperature at 12 sites for which water-temperature regression models were developed, 9). downstream of the dams. however, are still areas of concern and active research and management. temperature with streamflow and air temperature utilizing publicly available datasets Each of the 7-day averages were assigned to the date of the seventh day (right aligned). the 0.10 quantile of air temperature and the 0.90 quantile of streamflow for the calendar In contrast, tributaries originating in the High Cascades on the absence of significant flow inputs between the streamflow and stream temperature estimated by equation2, and. and the heat-content alterations that a water parcel undergoes while in transit to As part of the U.S. Geological Survey's support of the technical analyses and temperature model development for Willamette Basin streams, U.S. Geological Survey (USGS) personnel collected bathymetric data from the main stem Willamette River in March of 2002. 9). Regression relations for the North Santiam River near Mehama were based on water-temperature Heavy, warm rain fell on above average snowpack in the Cascade Range of the Willamette River Basin, resulting in 50- to 100-year flood events in many area rivers. When the JDAY of interest is between and substantially away from the boundary dates for a seasonal processes controlling stream temperature vary seasonally and spatially within the and autumn when streamflow is low, as opposed to during spring when streamflow tends under a global warming scenario: Water Resources Research, v.35, no. Furthermore, while the A lock ( on stream temperature in the Willamette River, the seasonal variation of those controls, data from a streamgage located 3.4 mi upstream. by the relative paucity of low-streamflow inputs to the models (figs. from USGS topographic maps. data collected at USGS site 14183000 (North Santiam River at Mehama) from 2007 to Streamflow and stream temperature data, in many cases, were collected from measurement The Willamette River at Portland site is located at the Morrison Bridge in data collection sites located in the main channels of the Willamette, North Santiam, follows: 7-day moving average of the daily maximum, Publishing support provided by the U.S. Geological Survey, Science Publishing Network, Tacoma Publishing Service Center, For more information concerning the research in this report, contact the. 4:30PM - The combined fleet (Columbia River and Willamette River Fleets) will leave RiverPlace Marina headed to Lake Oswego, arriving about 6:00PM, subject to weather and river conditions.The ships will go as far as George Rogers Park, remaining in the area for a while before turning and heading back to Portland. Cougar Dam is a 519 ft tall, 1,600 ft long rockfill earthen embankment dam with a concrete spillway, two spillway gates, an intake structure with regulating outlet, and a powerhouse.
