Puget Parks
Snow and ice are major sources of water for plants and animals in the parks and forests of the Puget Sound Basin, including Olympic, North Cascades, and Mt. Rainier National Parks, and Mt. Baker-Snoqualmie and Olympic National Forests. In the North Cascades National Park alone, there are more than 300 small glaciers that feed 245 mountain lakes and a myriad of streams, wetlands, and aquifers....
GW/SW Interactions
Knowing the interactions of ground water and river water can help reduce the fluctuation of water supplies in alluvial (sediment-deposit) river basins.
To develop general principles of these interactions in order to identify and analyze them, the USGS is reviewing the results of the numerous studies of these interactions in Pacific Northwest basins. The review will describe common...
Columbia Basin GWMA
More than 80 percent of drinking water in the mid-Columbia Basin comes from ground water. In Adams, Franklin, and Grant Counties, nitrate concentrations in water from about 20 percent of all drinking-water wells exceed the U.S. Environmental Protection Agency maximum contaminant level for nitrate. The three counties jointly formed the Columbia Basin Ground Water Management Area (GWMA) in...
Geomorphic Mapping, Dosewallips River
Located on the east side of the Olympic Peninsula in Washington State, the Dosewallips River drains about 100 square miles into Dabob Bay, an arm of Hood Canal. The Dosewallips is home to two species listed under the federal Endangered Species Act: Puget Sound chinook and Hood Canal summer chum.
To help the Port Gamble S'Klallam tribe protect and enhance the aquatic habitat of the...
GW Recharge
Hydrologists increasingly rely on computer watershed models to estimate groundwater recharge from precipitation on a regional scale. The model parameters used in simulations of recharge are various climatic, hydrologic, and physical characteristics of a watershed or stream basin. To date, the watershed models have not been evaluated to determine which model parameters are the dominant controls...
Lake Whatcom
Lake Whatcom, a large, natural lake in Whatcom County, is a source of drinking water for about 86,000 in the Bellingham area and a place for recreation. Elevated levels of mercury have been found in fish and sediment sampled from the lake. Possible sources of the mercury include atmospheric deposition, tributary discharges, landfills, dumpsites, and local mining operations.
To serve the...
Columbia Basin Irrigation
The National Marine Fisheries Service (NMFS), in its 2000 Biological Opinion for the Columbia Basin Irrigation Project (CBIP) in eastern Washington, asked for a determination of whether pesticides are present in irrigation return flows at levels that may harm or adversely affect salmon and steelhead species listed for protection under the Endangered Species Act. As the major resource manager...
Puget Hazards
Nationally, the USGS monitors and assesses geologic and hydrologic natural hazards. In the Puget Sound Basin, common hazards that also can cause damage include earthquakes and floods. Other hazards in the region that cause less damage or happen less frequently include landslides, debris flows, tsunamis, and volcanic eruptions.
Although much is known about these natural hazards,...
Methow River Basin
The Methow River Basin, located in North Central Washington in Okanogan County, is well known for its natural beauty, wildlife, outdoor recreation, and rural lifestyle. The Methow River and its tributaries are home to upper Columbia summer steelhead and spring Chinook salmon, which are both listed as endangered under the Endangered Species Act (ESA), and bull trout, which is listed as...
Groundwater Pesticide
The Environmental Protection Agency (EPA) is developing a rule requiring States to have a formal plan for the pesticides atrazine, simazine, alachlor, metolachlor, and other pesticides of concern in order to continue using them.
The Washington State Department of Agriculture (WSDA), the lead agency for a pesticide plan for Washington, will need an assessment of ground-water...
Island County
Island County consists of two major islands, Whidbey and Camano, and lies in northern Puget Sound, north of Seattle. Whidbey Island has an area of about 165 square miles and Camano Island an area of about 45 square miles, for a total area of about 210 square miles. Ground water is the primary source of water on the islands, and the ground-water system is fairly well understood, due in part to...
SUBASE Bangor
SUBASE Bangor is a 6,785 acre Navy installation located on Hood Canal in Kitsap County, Washington. Currently it serves as the home port to eight Ohio-class TRIDENT missile submarines, but historically the site served as a Naval Ammunition Depot. As a result of the historical activities at Bangor, numerous contaminated sites have been identified. Contaminants include ordnance chemicals, trace...
DataGrapher: Adjusting A Graph
Once you have generated your graph, you have a variety of options of where to go next. First, you can download the data that you used to create the graph by selecting here. This allows you to import the data directly into a spreadsheet or database package where you can do your own custom manipulation. Another option is to download the actual graphic as shown on the screen
DataGrapher: Walk-Through Guide
The Data Grapher is a set of online tools that allow users to create customized graphs and tables of a whole variety of time-series data that are served up by the U.S. Geological Survey. Now, if you've never been here before, it probably would be helpful to check out the Help system. Under the Help menu, there are a number of tutorials and example graphs. Under Example
USGS-CVO crew digs out Mount St. Helens' Sep. Lobe monitoring station.
During the first few days of Mount St. Helen's earthquake swarm in March 2016, the September Lobe monitoring station (located on the 1980-86 dome) was buried in deep snow and not transmitting data. USGS-Cascades Volcano Observatory Technicians Kelly Swinford and Amberlee Darold dug out the station on March 30, restoring data flow and improving our ability to monitor the

Culvert trap
Biologists place a culvert trap in locations that they need data from. Field crews will set up the culvert trap and check it daily, usually in the morning, to determine if a bear has been captured. Additionally, trap doors are checked via radio telemetry.
Culvert trap and bait
Biologists use road-killed ungulates such as deer, elk, or bison as bait in the traps.
At the capture site
At capture sites with road access, biologists drive to a trap with a bear inside to set up for collecting biological data.
An immobilized bear.
Biologists use a syringe pole to immobilize the captured grizzly bear. It takes approximately 10 minutes for a bear to become immobilized.
Ready to remove from the trap
Biologists have immobilized the bear and prepare to lift it out of the trap and onto the tarp for data collection. Once on the tarp the bear is easier to move.
Preparing for collection of samples
A biologist prepares to collect biological information from the bear they have captured. Biologists collect hair samples for genetic analysis, weigh the bear, and gather numerous measurements of the body, such as the head, paws, claws, teeth, etc. Overall condition of the bear is assessed as well, including a body fat measurement.
Getting the bear's weight
One of the first measurements taken is the bear’s weight using a quadpod and electronic scale.
