Alsea Bay is a coastal estuary consisting predominantly of open water, mud and sandflats at low tide, and some tidal salt marshes on edges and islands. This bay may be one of the most pristine estuaries on the Oregon Coast owing to lack of industrial activity. The Alsea River Watershed drains approximately square miles of land, and is home to.

The project took place in the lower reaches of Little Lobster Creek, with restoration activities seeking to address two limiting habitat factors for salmonids in the watershed—with a particular emphasis on Oregon Coast coho, listed as threatened on the Endangered Species Act—elevated summer stream temperatures and a lack of instream wood, as identified by a USFS Watershed Analysis. The falls are located within the BLM's popular Alsea Falls Recreation area, which includes a campground and picnic area. Surrounding the falls, especially when the river is lower, are smooth rock slabs that, on clear days, attract sunbathers and swimmers like ants to sugar. what occurred in the Alsea River watershed will surely arise again. In addition to having lower survival in the wild environment, hatchery-produced listed species, conduct a thorough analysis of the benefits and risks to determine if a net biological benefit is likely to be achieved.

The Alsea Watershed Study ( °N, °W) was established in September ().The study area is located in the Siuslaw National Forest in the central Oregon Coast Range, draining highly-dissected terrain with short, steep, soil-mantled hillslopes underlain by the Tyee Formation, a rhythmically Eocene interbedded sandstone and mudstones deposit.

Relevant information from the Lower Alsea River Watershed Analysis (USFS ), the Lower Alsea River/Drift Creek Water Quality Restoration Plan (USDA b), and analyses for the Project, including the Aquatic Conservation Strategy (ACS) Consistency Assessment (Appendix D), was incorporated by reference into this environmental analysis.

Upper and Lower Alsea River Watershed Fish Passage Restoration is a proposal to restore fish passage to approximately three miles of anadromous and resident fish habitat.

The project would replace six stream crossing culverts that currently block fish passage with six culverts that would allow fish passage. The hydraulic response of the Alsea watershed study to the first harvest produced results to in the streamflow of Needle Branch creek.

Deer creek was shown to be a suitable control and that Upper and Lower Needle Branch respond similarly. There is still a lot of work to be done and suspended sediment analysis to complete.

The model is described in ODFW Information Report Watershed overview The Little Lobster Creek sub-watershed comprises 2, hectares within the Five Rivers/Lobster Creek watershed of the Alsea River basin. Flow originates at about ft elevation in two steep headland.

The concern results from a lack of knowledge regarding the actual environmental effects caused by contemporary forest management activities at a watershed scale. Three paired watershed studies of unprecedented scope, along with smaller, related studies, have been established to help guide future stream protection practices in the Pacific Northwest.

Preacher Creek lies within a 1, hectare sub-watershed of the Five Rivers/Lobster Creek watershed of the Alsea River basin. Overall, its drainage pattern is dendritic, however the majority of the basin exhibits drainage characteristics that are functionally pinnate.

The main direction of flow is northeast, joining Lobster Creek at RM Oregon Explorer Top Menu. Home; Search; Topics. Animals and Plants. Biodiversity; Birds; Conservation; Habitats. A watershed analysis is an in-depth examination of a watershed’s biological and physical characteristics.
