Our researchers at Ocean Blue needed a way to continuously monitor water levels and temperatures prior to planting trees that will one day create a stream canopy of shade that will lower water temperatures that are more a consistent year around temperature in return will Chinook Salmon will have a safe habitat to rest along their long journey up the Willamette River Basin.
With Summer and Flash flooding in the winter months the water conditions are alternating warmer and cold conditions. The OBP needed instrumentation that could not only withstand the harsh conditions but would also have enough battery power to last for multi-year deployments.
With Funding from Macy's Ocean Blue was able to obtain the equipment needed to collect in stream research quality data on many types of water quality measurements and data collection and we are putting this equipment into action. Our goal is to monitor the Willamette River for safe water measurements like water levels, water temperatures, and we are focusing on confluence of urban streams that are flowing litter and toxins into the Willamette River.
Our Found Solution for water data collection interments that make impact
With these limitations, the WVU team set out to identify alternative water-level-data-logging instruments. They began experimenting with HOBO® U20 Water Level Loggers from Onset, a Massachusetts-based manufacturer of portable data loggers and weather stations.
Unlike the previous loggers used, which relied on bulky vent tubes and desiccant packs, the HOBO devices feature a sealed, non-vented design to make logger deployment in the basin faster, easier and more maintenance-free. The loggers also feature a USB-based optical interface for high-speed offload of the collected data in wet environments. The optical design also eliminates the need for failure-prone mechanical connectors found in many traditional water-level-logging instruments.
To prepare the 30+ loggers for deployment, they were first connected to the research center's computer via USB cable and configured in a matter of minutes using accompanying HOBOware® Pro graphing and analysis software. Once configured, the loggers were submerged in monitoring wells using bulk 3/16" stainless steel cable attached to hanging bolts. According to Donovan, readings are taken every hour around the clock and synced to a uniform time base.
"The loggers are programmed to record absolute pressure at hourly intervals," he explains. "The accompanying software subtracts barometric pressure from absolute pressure recorded in the well and then converts the pressure reading to sensor submergence. The sensor submergence is added to the sensor elevation yielding the mine-water hydraulic head elevation."

The goal of this project is to restore habitat for threatened riparian animal species by improving water quality and stream stability with an ecological restoration approach. Native plants will be established throughout 50% of the stream section after removing invasive species such as Reed Canary Grass. Through partnership local schools, cities, and neighbors in community capacity building service learning project.
Pre-implementation includes invasive species removal and establishing 50% native plants. The completion of the project follows with post-implementation water quality monitoring and project effectiveness, including weekly water samples for three years, frequent plant monitoring, and using strategies to maintain consistent water temperatures to improve survival rates.

Oregon State University interns, OBP tracks animal species through waterfowl counts and amphibian counts using frog traps.
