Bulrush growing in Malheur Lake
Following a wet winter, bulrush is shown growing in Malheur Lake. Emergent vegetation like bulrush provides nesting habitat and food resources for birds.

Water quality sensor inspection - Willamette River
Hydrologic technician, Ann McGowan, shows OMSI representative a water quality sensor deployed in the Willamette River near OMSI. This sensor monitors water temperature, dissolved oxygen, chlorophyll, blue green algea, specific conductance and pH. The sensors need cleaned every 4-6 weeks.

Water Sampling on the Willamette River
Hydrologist Kurt Carpenter demonstrated gathering a water sample from the Willamette on the docks at OMSI. The netting gets pulled through the water and is then funneled into a sample bottle.

Microcystis aeruginosa under the microscope
Microcyctis aeruginosa is a freshwater cyanobacteria that produce cyanotoxins such as Microcystin. Cyanotoxins are harmful to humans and pets.

Water level and temperature sensor in the Middle Santiam River
New USGS water temperature and water level gage installed in Middle Santiam River in the Middle Santiam Wildness Area upstream of Green Peter Dam. This gage will help characterize habitat conditions for multiple life stages of spring Chinook salmon in this river reach.

The Diatom Synedra under the Microscope
Diatom, Synedra, from the Greek word synedria meaning "a sitting together". The genus Synedra has long, needle like cells that can exist singly or radiate in colonies.

Willamette River near Harrisburg, Oregon
Photo taken of the Willamette River near Harrisburg, Oregon during the "heat dome" of 2021. This historic heatwave occurred in Oregon and the greater Pacific Northwest in late June of 2021 breaking high temperature records, some by several degrees.

Quartzville Creek near Cascadia Oregon
An outside gage set-up at Quartzville Creek near Cascadia Oregon. Graduated staff plates installed at various heights to capture the range in water levels. Staffs are used to get river level readings hydrologic technicians need to calibrate electronic sensors. The vertical grey metal pipe is a crest stage gage (CSG).
