Lake Abert, Oregon is one of the 20 terminal lakes identified by USGS partners as priority ecosystems for study by the Saline Lakes Ecosystems IWAA.

How hot do wildfires get? 

• 570 F degrees - TEMPERATURE AT WHICH WOOD WILL BURST INTO FLAMES
• 2,200 F degrees - TEMPERATURE WILDFIRES COULD REACH IN EXTREME CONDITIONS

Fast-moving, highly destructive debris flows triggered by intense rainfall are one of the most dangerous post-fire hazards. The risk of floods and debris flows after fires increases due to vegetation loss and soil exposure. Cases of sudden and deadly debris flow are well documented along the western United States, particularly in Southern California.

Pair of Pelagic Cormorant (Urile pelagicus) nest along the sea cliffs of a grotto on St. Matthew Island. The island is home to over 1.6 million nesting seabirds, including murres, kittiwakes, puffins and auklets. 

Orange streams are increasingly common in the Brooks Range of northern Alaska. The orange stream color reflects oxidized iron, but also often indicates elevated heavy metal concentrations. Our ongoing study aims to document these occurrences and the timing of their onset.

Coral reefs provide ample opportunities for recreational activities and fishing and add important cultural value to coastal communities. 

They also bolster biodiversity by giving food and shelter to many species. 

The structure of a reef helps dampen waves and protects coastlines from storms and erosion. 

Goose Lake, on the Oregon-California border, is one of the 20 terminal lakes identified by USGS partners as priority ecosystems for study by the Saline Lakes Ecosystems IWAA.

How Streamgages are Used in Postfire Flood Forecasting

Stream data is recorded in real time and posted online.

Stream data include water level, velocity, and turbidity.

During storms, rainfall data is compared to the stream data.

The National Weather Service uses the data to issue flood warnings.

Many new big sagebrush (Artemisia tridentata) plants that have just sprouted from the ground in the Morley Nelson Snake River Birds of Prey National Conservation Area in Idaho.

A field crew member collecting stick-point intercept data at a Project ROAM (Rapid and Other Methods for Assessment and Monitoring) plot. A meter-long 'stick' is dropped and five recordings of vegetation are collected by dropping a pin flag along the stick. The vegetation it comes into contact with is recorded to estimate cover.
