The Geotech ETL Water Level Meter is a portable instrument used to accurately measure water levels in monitoring wells. The well tape is mounted on a lightweight steel and aluminum storage reel with rugged aluminum frame. The polyethylene-coated engineer's tape is accurate to 1/100th of a foot.
The sensor consists of a stainless steel and FEP probe, and it relies on fluid conductivity to determine the presence of water. When the instrument contacts water, an audible signal and visible green light activate. The meter also features adjustable sensitivity, which is used to prevent false triggering.

CrowdHydrology sources water level data from public's text messages
Chris Lowry’s idea was simple: set up staff gauges on local streams and leave a sign requesting passersby read the water level and text the data to a phone number. Data from text messages would be recorded and then posted to a website for public use. 
 It was the beginning of CrowdHydrology, a crowdsourcing project that recently gained U.S. Geological Survey support for expansion into several Midwest states. Though it won’t generate as much data as official USGS stream gauges, the project will generate data points that supplement those lost from official gauges shut down following federal budget cuts. 
 Lowry, an assistant professor of geology at the University at Buffalo, set up eight pilot sites in New York in 2011 in an attempt to crowdsource water level data.

Long-standing environmental monitoring programs have the power to support a large number of research initiatives and policy changes—however, actually starting these networks can prove challenging. Not only is starting the program difficult, but keeping things operational for decades to come has also been challenging for environmental professionals hoping to make an impact with applied research. 
 
Jason Polk, Professor of Environmental Geoscience and Director of the Center for Human GeoEnvironmental Studies (CHNGES) at Western Kentucky University, is all too familiar with this process.

The prairies of Saskatchewan can be described as one of the least water-secure parts of Canada, making water quality monitoring essential for informed resource management in a region already facing water insecurity. While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. 
 
Having grown up spending summers on the shores of Lake Huron, Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan , has always been dedicated to the protection of water resources. 
 
Looking back fondly at her childhood playing along the shore, Baulch also recalls the invasion of quagga mussels during her teenage years and watching the lake change as a result.
