    Statistical information may be estimated and may be inaccurate. A tributary to the South Fork of the Salmon River already flows through one of the open pits and contributes to water contamination in the South Fork of the Salmon River. The horticulture group is also working on gardens and selling plants to raise money. If the watercourse is not known to have an officially or colloquially recognized name, this field is left blank. Key Cataloged Waterfalls which are Cataloged we have visited and surveyed in person.

    Develop plans to help the Alsea Emergency Preparedness Committee visualize the areas of greatest concern. This is because the town of Alsea does not have a public works department, and is unincorporated. Meandering through a downcut channel between U. The Shoshone, Nez Perce, Bannock and Paiute tribes have used the river for fishing and hunting for generations.

South fork Alsea River Watershed analysis book

This figure is not often easy to establish with a high degree of precision and as such will often be estimated. Afterwards, it receives its first significant tributary, Tenmile Creek, on the right bank. While the river has had only minor impoundments on its tributaries, it has two fish hatcheries, one on the North Fork and another downstream on the Fall Creek tributary, the site of the Oregon Hatchery Research Center.

The South Fork Salmon watershed is one of the linchpins in the ongoing work to restore endangered salmon and steelhead to Idaho.

The effect of the rain was most evident at the Marys River. For smaller waterfalls, this figure will generally not differ much from the Average Width measurement, but for broader waterfalls - especially those that feature a crest that isn't constricted - this figure can at times be consideraby larger.

A trail here descended to the river bank before petering out. This path climbed for a half mile to a road where we turned right for another half mile before descending on another half mile trail to the junction we had passed that morning.

Sea-run cutthroat trout fishing is usually good. The South Fork is an important Northern California habitat for anadromous fish see section below and sediment has severely degraded conditions for these fish as well as other aquatic life forms.

We maintain records for these features out of historical importance. Distribute the findings in the Alsea Valley Voice.

Green Peak Falls

Although it is not a large creek, only about 2. Form The system of classification of waterfall forms we use is a heavily modified derivative of the classifications outlined by Greg Plumb in his "Waterfall Lover's Guide to the Pacific Northwest" books. Since the decline in timber harvests in the s, sports fishing provides modest support for businesses along the river.

Cedar Creek flows west and turns south-southwest, flowing also in a steep, undeveloped gorge. Inundated Inundated Waterfalls have been submerged beneath lakes or reservoirs, usually a result of impoundment of a river behind a dam, and most often no longer functionally exist there may be rare exceptions.

Like the Average Width measurement, this measurement will take into account the difference in width at the top and bottom of the waterfall as much as possible, but will often be made based on the width of the crest of th falls alone.

While plumb uses eight distnct forms, we wanted further granularity and opted to break down the hierarchy twofold: first based on the overall pitch of the waterfall, and then based on what shape the fall takes as it makes its descent.

Confirmed Confirmed Waterfalls are known to exist, should be relatively accurately mapped and geotagged, and the statistical information available will often be dependable. Unknown Waterfalls marked as Unknown are either suspected to exist based on heresay or a hunch, or we have received unverified information suggesting a waterfall may exist near the location provided but cannot corroborate it in any way.

Work with other individuals to update the GIS information so that aspects of the systems which are lacking can be repaired. The South Fork also has a number of protected areas along its course. To reach the area from Highway 99w we turned west near Monroe at a sign for Alpine.

The Profiles can be used to help initiate planning discussions among conservationists and stakeholders about maintaining watershed health through conservation. The main stem of the river begins at the confluence of the North and South forks near the community of Alsea and flows approximately 43 miles to the coast.

Regardless of intentions, mining operations are inherently toxic for river health, water quality and the environment, and the scale at which this project is proposed would have catastrophic repercussions for the South Fork of the Salmon River and the downstream communities that depend on a healthy Salmon River system.

The estuary and nearby coves along the coast provided abundant foodstuffs as did seasonal gathering treks to the upper valley.

This will help to document stub out locations and meter bases locations in order to connect them on GIS to the potable water system. This figure is not often easy to establish with a high degree of precision and as such will often be estimated. Although much of the Alsea River is bordered by private property, access is generally good.

This information may be changed at any given time to ensure accuracy.The runoff ratios in these catchments increased ~10% in Alsea, 13% in Nehalem, 14% in Marys over the analysis period. Comparatively, there was strong evidence (p River (% SNC) and Siletz River (%) atlasbowling.com by: 1.

The South Fork of the Salmon River is designated as critical habitat for endangered chinook salmon and steelhead and threatened bull trout. It is also home to westslope cutthroat trout, another sensitive species.

The South Fork Alsea watershed encompasses approximately 40, acres in the central Oregon Coast Range approximately 20 miles southwest of Corvallis.

The geology of the watershed is composed of a mixture of volcanic and sedimentary rocks. It is highly dissected by intermittent and perennial streams which feed into the S.
