Water availability, distribution, quality and quantity are critical habitat elements for fish and other water-dependent species. Furthermore, the availability of water is also a pre-requisite for a number of human activities. The density of weather and hydrology observation sites on the North Slope is orders of magnitude less than in other parts of the U.S., making it difficult to document hydrologic trends and develop accurate predictive models where water is a key input. The information that does exist is scattered among many entities, and varies in format. This multi-year data rescue effort project brings together these scarce and scattered hydrology data sets, including high-priority datasets held by the Bureau...

Alaska’s freshwater resources, vitally important for salmon and other species, are vulnerable to changes resulting from climate change. Though temperature is a critical element in the suitability of aquatic habitats, Alaska’s stream and lake temperature monitoring is occurring through independent agencies/partners without a means to link and share data. Because a coordinated network of monitoring data can help scientists and managers understand how aquatic systems are responding to climate change, conducting an inventory of past and present stream and lake temperature monitoring efforts has been identified as a priority science need for Alaska. This project consolidated existing monitoring site locations and attributes...

The USGS and Arctic National Wildlife Refuge Staff operate and maintain a streamgage at Hulahula River near Kaktovik, Alaska. Data from this station is necessary to complement glacier mass-balance studies and provide information necessary to project stream flow regimes under various scenarios of climate change. This project includes operation, acquiring real-time data, analysis of the data, and internet access. The gauge continues to operate as of 2017.

The Arctic LCC and partners are supporting stream gages infive different river systems. The rivers being monitored fall intothree broad categories: glacial streams originating in the BrooksRange (Hulahula river), streams with only minor glacial input(Kuparuk, Canning & Tamayariak rivers), and non-glacialstreams that are contained entirely within the Arctic CoastalPlain, such as the Putuligayuk River

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
