Depoe Bay, situated on the Oregon Coast about 100 miles south of the mouth of the Columbia River and 13 miles north of Yaquina Bay at Newport, Oregon, is a small, rock-bound tidal lagoon much affected by man's activities.
In its natural condition, Depoe Bay was very shallow, with a...
"The City of Newport is proposing to complete a major wastewater treatment facility upgrade. The project includes laying a new primary pipeline from Nye Beach south to and under Yaquina Bay and continuing south to the new wastewater treatment facility in South Newport..." Solicits public comments. Includes a map and...
Sediments from Yaquina Bay and the Yaquina River from the river mouth to river mile 14, and from Depoe Slough at river mile .25 and 1.5 were tested. While sediments near the river mouth were "extremely clean," and main-channel sediments were relatively clean, Depoe Slough sediments were more polluted. Alternatives...
This evaluation covers the approximately 30,000 cubic yards of material to be excavated from the South Beach Marina Federal project channel. . . The authorized South Beach Marina Federal project channel is 10 feet deep, 100 feet wide and 2,035 feet long. . . The channel has not been dredged...
This report describes sediment testing done on the Yaquina River benthos between river miles 6 and 11 (a section between Yaquina and Toledo). The sediments were found to be safe for in-water disposal, thus enabling dredging to proceed.
"Nine (9) sediment samples and 1 QC duplicate were collected from Yaquina Bay and South Beach Marina (see Figures 1) on May 31, 2000. All samples were submitted for physical analyses, with 4 samples analyzed for metals (9 inorganic), total organic carbon (TOC), pesticides/polychlorinated biphenyls (PCBs), phenols, phthalates, miscellaneous extractables,polynuclear...
The objective of this Biological Opinion (BO) is to determine whether the action to restore emergent vegetation to wetlands on Sauvie Island is likely to jeopardize the continued existence of Upper Willamette River chinook salmon and Lower Columbia river chinook salmon or destroy, or adversely modify proposed critical habitat.
On April 7, 2000, the National Marine Fisheries Service (NMFS) received a request from the U.S. Army Corps of Engineers, Portland District (COE) for Endangered Species Act (ESA) section 7 formal consultation for programmatic coverage for a proposed Regional General Permit (RGP) for certain stream restoration activities (habitat restoration using...
In a January 26, 2000 letter, the Portland District Army Corps of Engineers (COE) requested Endangered Species Act (ESA) Section 7 informal consultation with the National Marine Fisheries Service (NMFS) on the proposed issuance of a Clean Water Act Section 404 permit (Permit ID No. 00-32) to allow an instream...
On October 16, 2000, the National Marine Fisheries Service (NMFS) received a request from Portland District Army Corps of Engineers (COE) for Endangered Species Act (ESA) section 7 consultation for issuance of a Corps permit to Morse Brothers (Corps No. 2000-00844) for a habitat restoration project that will connect an...
This is a transcript of a meeting between officials of the Army Corps of Engineers and various local stakeholders about a review study of the Yaquina River, and possible improvements the Corps might make to the river. Participants included local officials, representatives of local industries and concerned citizens. Facsimile copies...
This 1965 meeting was prompted by local requests and in response to flooding and high water from the storms of December, 1964-January, 1965. Local stakeholders voiced their concerns about the river to representatives of the Army Corps of Engineers.
Sediment along the western end of the Newport North Marina Jetty is free of contaminants such as metals, PAHs, pesticides, PCBs, phenols and TBT. According to guidelines developed to implement the CWA and MPRSA, the sediment is acceptable for both in-water and upland disposal.
Seed size, abundance, viability, dormancy, and germination requirements strongly influence plant establishment and therefore are important considerations in restoration of native vegetation. These characteristics provide criteria for selection of suitable species, development of collection and pretreatment methods, and determination of seeding densities. The first set of objectives of this study...
The elevations and characteristics of floods are major factors that influence land-use planning of the flood plains of any stream. As the lowlands become more intensively used, it becomes increasingly important to have a firm basis for assessing the risk of flood damage. Land-use zoning is not only a legal...
