Operational remote sensing on the verge of changing water resources management- Kyle Blasch

Have you ever thought that our nation’s satellites could be put to better use than watching you drink your fifth cup of coffee as you prepare for final exams? If so, then this is a project that you would enjoy.  The hydrologic community is at a pivotal moment in the application of remote sensing into everyday decision making and we need you.

Examining controls on the solubility in the ocean of iron from dust and volcanic ash- John Crusius

Biological productivity in the Gulf of Alaska is limited by availability of the micronutrient iron. Dust derived from Alaskan glacial flour and from Asian deserts, and ash from Alaskan volcanoes, episodically supply iron from the atmosphere. This internship would carry out studies on archived material from a variety of dust and ash samples to examine controls on the supply of this...

Effects of Nanophyetus salmincola on the Health and Survival of Puget Sound Steelhead

Low early marine survival rates of Puget Sound steelhead (Oncorhynchus mykiss), the state fish of Washington, have contributed to its dramatic population decline and current listing as a “Threatened Species” under the Endangered Species Act. Determining the cause(s) of this elevated mortality remains a primary objective of the Salish Sea Marine Survival Project, a large US / Canada effort...

Genomic Mechanisms that Underlie Lack of Recovery of Prince William Sound Herring Following the 1990s Collapse

In the decades following the Exxon Valdez Oil Spill (EVOS), it has become increasingly apparent that oil can be toxic at extremely low concentrations to developing fish embryos including herring, where some toxic phenotypes may be apparent during embryogenesis, but some are delayed until later in life. Therefore, acute and lingering oil may act as an insidious selective force within...

Early Detection Monitoring May Not Be Sufficient for Invasive Mussels in the Columbia River Basin

The ecological and economic costs of an invasive quagga or zebra mussel infestation in the Pacific Northwest of the U.S. would be significant. The development of invasive mussel monitoring programs in the Pacific Northwest provides a unique opportunity to evaluate a regional invasive species detection effort early in its development. Although efforts are underway to monitor for the presence of...

Salmonid Population and Life History Research in Tributary Stream and River Habitats and Response to Dam Removal

Juvenile anadromous salmonids all spend some portion of their lives in freshwater. This time may vary from days to years depending upon species and run. Spring Chinook Salmon and Coho salmon generally spend one year in freshwater and Steelhead may spend up to five years in freshwater prior to beginning their journey to sea. Several projects at WFRC – CRRL are investigating populations, life-...

MODFLOW-NWT model used to simulate groundwater storage changes in the Quincy Basin, Washington

A three-dimensional, groundwater flow model (MODFLOW-NWT) was developed to
examine groundwater storage changes in the Quincy Basin, Washington. The
model was calibrated to conditions from 1920 to 2013. The model was used to
(1) determine the change in groundwater storage from 1920 to 2013 , and
(2) simulate the potential effects of increases in pumping.

Image of the Week - Elwha River Dam Removal

In September 2011, the largest dam removal project in U.S. history began. 

Two dams built on the Elwha River in the early 1900s created two reservoirs in northwestern Washington. They also greatly reduced the amount of sediment flowing to the river’s delta and blocked salmon migration upstream into Olympic National Park.

Atmospheric rivers are a global weather phenomenon that can bring large amounts of rain or snow to the U.S. West Coast each year. These rivers of wet air form over the Pacific Ocean near Hawaiʻi and pick up large amounts of moisture from the tropics and on their way to the West Coast. This moisture is carried in narrow bands across the Pacific Ocean to California, Oregon, Washington and Nevada.
