Smart-Phone Technology Helps Protect Salmon Habitat in Washington State –USGS, in cooperation with Seattle Public Utilities, embedded high-tech sensors typically found in devices such as smart phones into a new type of equipment to monitor riverbed movements that can help protect spawning habitat for endangered salmon. The new method is published in the Journal of Hydrology. Scientists took the high-tech sensors, also referred to as “accelerometers,” coupled with data-logging circuits, and placed them in tubes that were then buried in the Cedar River’s grovel in 26 salmon-spawning locations.

Salmon, habitat management, and water quality of the Molalla River in northern Oregon –USGS, in cooperation with the Molalla River Improvement District, released a report that discusses the geomorphology, aquatic habitat, and water-quality conditions of the Molalla River, located in northern Oregon. The Molalla River is an important regional resource for people and salmon, and Congress recently nominated the upper section for Wild and Scenic River status. The river, however, has been flood prone in recent years, and the river has limited runs of anadromous salmon despite seemingly suitable and inviting aquatic habitat. This study is the most comprehensive of the Molalla River completed to date and offers important insight for the river-management and restoration community on this river as well as other Pacific Northwest rivers.
Barnegat Bay Restoration in New Jersey –USGS, in collaboration with New Jersey Department of Environmental Protection and other interested parties, are developing an improved quantitative understanding of critical physical, chemical, and biological conditions and processes that are relevant to the health of this important coastal resource. This understanding will be the foundation for other scientific analyses of Barnegat Bay's hydrologic and biologic systems that may proceed contemporaneously or subsequent to this project. (Read more)
60-year tracking of sediment in the Arkansas River near Tulsa Oklahoma –USGS, in cooperation with Tulsa County, assessed fluvial sediment transport and changing channel morphology in the Arkansas River near Tulsa, Oklahoma over a 60-year period since 1950. Sediment rating curves serve as simple models for estimating annual sediment fluxes and can assist planners in future riverine development and restoration projects. (Full report)
