Tribal members welcome "families" from other Salish Sea Indian and First Nation Tribes.

This photo from our second cross section is an example of significant changes to the river. Data was collected from this location in 2009 from a manned boat, with no issue. Upon return to the same cross section in 2013 we found a 2-4 ft hydraulic feature exposed. Backwater from the Great Works Dam hid this feature previously.

The Hell Creek and underlying Fox Hills Formations are present at the land surface along the margins of the Williston Basin, but otherwise are the deepest bedrock aquifers that are commonly used in the basin.

An early streamgage is used to measure water levels on San Saba River. USGS crews would visit this equipment to collect water level readings.

The Bois de Sioux river channel near White Rock, SD.

Seam or bed of Pliocene lignite from a mine in the Balkan endemic nephropathy (BEN) area of Romania. Rainwater falling onto the surface penetrates into the ground, becoming ground water, and leaches toxic organic substances from this coal.

Native Americans of the Miwok tribe in the northern Sierra Nevada, California carved these basins into the granite bedrock to produce salt for trade. They filled the basins with water from a salt spring and let the water evaporate, leaving a salt residue in the basin. The basins are about a meter in diameter and span the area of a football field.

Bald Cypress trees are iconic symbols of wetlands, but their distribution and range may be vulnerable to climate change impacts.

Establishing a release site for salmonids implanted with radio transmitters. Behavior and movement of salmon are monitored as they migrate through the Toutle River.

Prairie Creek nr. Silver Creek is a tributary of the Platte River. The photo was taken to capture Autumn's colors amplified by water.

A USGS technician finishes construction on a monitoring station used to monitor surface salinity and temperature below Faka Union Canal Weir #1, Florida. By measuring hydrologic conditions here, researchers found that freshwater flow rates help maintain warm water pockets in downstream areas of the canal.

Great Lakes water availability studies conducted by the U.S. Geological Survey aim to help characterize how much water the Basin has now, how water availability is changing, and how much water it can expect to have in the future.
