Rainbow Trout with a Pink mouse tail Green Peter offers an excellent kokanee and landlocked chinook salmon fishery, with a 25 kokanee limit. There are also largemouth and smallmouth bass. Green Peter and Quartzville. Below Ferrin bridge you'll have a mile or two of flat water before reaching "Devils Kitchen"- easly identifiable by the green bridge just before the rapid. Below that the river gains in volume from the North Fork of the Willamette on river right. Another miles of navigable class II remain.

The river and its principal tributaries dr square miles (12 percent of Oregon), with the basin's runoff fluctuating dramatically between the heavy precipitation of the winter months and relatively rain-free summers.
The Willamette River Basin is approximately miles in. Willamette River Basin Project Supplemental Biological Assessment. JNOAA Fisheries released a biological opinion (BiOp) addressing the effect of the operation of 13 dams on Willamette River tributaries and 42 miles of levees on 13 populations of salmon and steelhead protected by the federal Endangered Species Act (ESA).
The Willamette River is a mile ( km) tributary of the Columbia River in the U.S. state of upper tributaries of the Willamette originate in mountains south and southeast of the twin cities of Eugene and by the confluence of the Middle Fork Willamette River and Coast Fork Willamette River near Springfield, the main stem meanders generally north from source to Mouth: Columbia River.
Cougar Dam is a foot ( m) tall rockfill hydroelectric dam in the U.S. state of has a gated concrete spillway and a powerhouse with two turbines totaling 25 megawatts of electric power.
The dam impounds the South Fork McKenzie River about 42 miles (68 km) east of Eugene, Oregon, creating Cougar Reservoir which has a storage capacity ofacre feet (, m 3).Location: Lane County, Oregon, USA.
Thermal Effects of Dams in the Willamette River Basin Without-Dam Flow Estimates at Dam Sites. Estimates of without-dam streamflow at 11 of the USACE dam sites were constructed Green Peter measured dam releases, estimated changes in storage as a function of reservoir stage measurements, and a correction for evaporative losses from the reservoirs.
Methods were developed to assess the effects of dams on streamflow and water temperature in the Willamette River and its major tributaries. These methods were used to estimate the flows and temperatures that would occur at 14 dam sites in the absence of upstream dams, and river models were applied to simulate downstream flows and temperatures under a no-dams scenario.
The Willamette Water project was a collaborative effort of faculty from Oregon State University (OSU), the University of Oregon (UO), Portland State University (PSU), and the University of California - Santa Barbara. It was funded primarily by grants from the National Science Foundation with additional support from the National Oceanic and Atmospheric Administration.
Thermal Effects of Dams in the Willamette River Basin Green Peter Dam. Green Peter Dam impounds Green Peter Lake on the Middle Santiam River upstream of Foster Lake. The two major inputs are Quartzville Creek and the Middle Santiam River, with the former providing about 30–40 percent of the flow during summer.
The Willamette River Basin Planning Atlas offers a valuable resource for anyone interested in the region's past, present, and future. Using a dazzling variety of color maps, charts, and photographs, the Atlas presents a vast amount of information intended to Cougar a long-term, large-scale view of changes in human and natural systems within.

The Santiam River is a tributary of the Willamette River in northwestern Oregon and drains an area of 1, square miles. The U.S. Army Corps of Engineers (USACE) operates four dams in the basin, which are used primarily for flood control, hydropower production, recreation, and Willamette River Basin improvement.

The Willamette River is said to be one of the most important tributaries of the Columbia River, and is one of the most important water bodies to be seen flowing through the state of Oregon in the United river also accounts for some 15% of the flow into the Columbia River, with the Willamette River itself having an approximate length of : Khushboo Sheth.
The bridges that span the Willamette River in Portland are critical parts of the region’s transportation system. Several hundred thousand people cross these bridges each day, connecting commerce and community.
Multnomah County owns and maintains six bridges on the Willamette River: The Broadway Bridge is the most complicated drawbridge to open.
The Willamette River stretches nearly miles from its headwaters at Waldo Lake near Eugene to the confluence with the Columbia River in North Portland. The Willamette River Basin is the largest watershed in the state, covering more t square miles. Portland is at the lower end of the drainage basin and is the most urbanized part of.
Calapooia River, Oregon - 3 dams removed, Shearer Dam, one of three small dams removed on the Calapooia River. The Calapooia is one of the upper Willamette Rivers without a major hydroelectric dam. But three small dams block fish passage. A video summarizes the project to remove the Brownsville, Sodom, and Shearer Dams.
