Abstract:: In 1949, the Army Corps of Engineers dredged Coos Bay. “Despite objection of local residents, commercial clam diggers, and the Fish Commission” the Corps dumped dredging spoils on a commercially important clam bed, and destroyed much of it. “This year, with an earlier start and more data, it is hoped...

Notes on proposed channel dredging in Coos Bay

Creator:: Tollefson, Roger D., Marriage, Lowell D., and Oregon Fish Commission. Shellfish Program
Abstract:: The Army Corps of Engineers dredged in Coos Bay in the fall of 1948, dumping dredge spoils on a large clam bed and killing the clams. Although Fish Commission biologists were unable to relocate the original planned dumping site, they observed the resulting increased pressures on remaining clam resources, and...

Impacts of dredged material disposal on estuarine benthic macrofaunal communities in Coos Bay, Oregon

Creator:: Erman, Lisa T.
Abstract:: Hopper dredge disposal of coarse grained sediment was investigated between May and September, 1986, at a designated disposal area, Site G, in Coos Bay, Oregon. The objectives of the study were to: (a) identify and describe the benthic macrofaunal community structure at Site G during May and September, 1986; (b)...

Investigation of proposed dike construction in Coos Bay at Eastside, Coos County, Oregon

Creator:: Marriage, Lowell D. and Oregon. Fish Commission. Shellfish Program
Abstract:: Reports on an investigation of a proposal by the Evans Products Company of Coos Bay to construct a dike in the bay. Investigators found negligible quantities of the Eastern soft-shell clam, and therefore did not oppose the proposed dredging and construction. Includes a hand-drawn map and a survey report.

Findings of compliance, dredged material disposal activities : Yaquina Bay and River federal navigation channel

Creator:: United States. Army. Corps of Engineers. Portland District
Abstract:: 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...

Construction of bulkhead and log boom at Empire, Oregon by the Coos Bay Pulp Corporation

Creator:: Morgan, A. R. and Oregon. Fish Commission. Shellfish Program
Abstract:: An area in Coos Bay was dredged to make room for a log boom. This terse 1953 report concerns a bulkhead constructed to hold the dredging spoil and the proposed new log boom.

Field verification of a mathematical model for the physical fate prediction of dredged material instantaneously disposed at sea

Creator:: Hollings, William H.
Abstract:: Dredged spoil plumes are monitored during nine hopper dredge disposal events in 186 foot water depths offshore near Coos Bay, Oregon. Position and solids volume concentration characteristics of the plumes are established. Computer simulations of the monitored events are executed using the WES modified version of the Koh-Chang instantaneous disposal...

The 1960 Yaquina Bay clam study

Creator:: Snow, C. Dale, Demory, Darrell, and Oregon Fish Commission
Abstract:: In 1960, the Army Corps of Engineers was planning to extend the jetties and to deepen the channel at Yaquina Bay. The Corps proposed to dump its dredging spoils in Sally's Bend, a highly productive part of the bay. In response to this request, in the summer of 1960, Fish...
