Overview
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 a rugged aluminum frame. The polyethylene-coated engineer's tape is accurate to 1/100th of a foot.
Mechanics
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-Term Monitoring in the Chautauqua Lake Watershed
With a widely developed shoreline, Chautauqua Lake experiences influxes of non-point source pollution that have historically impacted the health of the lake. The Chautauqua Lake Association (CLA) has been monitoring the lake for over two decades, reporting on changes that have occurred over the years. A pair of local lake advocates, Jane and Doug Conroe, have lived on the lake for over 40 years and have played an important role in establishing monitoring programs and facilitating consistent data collection throughout the watershed. Doug has been involved with the Chautauqua Lake Association (CLA) since the pair moved to the area in 1980, and is currently serving as the Executive Director.

No Red Herrings: Data Driving the Largest Salt Marsh Restoration in the NE USA
The Herring River system encompasses around 1,000 acres in the Towns of Wellfleet and Truro, Massachusetts. In 1909, the Chequessett Neck Road dike was built at the river’s mouth, drastically limiting tidal flow. Today, it’s one of the most restricted estuaries in the northeastern United States. As a result, the area has suffered environmental decline, including poor water quality, hypoxia, lower pH, and salt marsh degradation. In 2023, the Town of Wellfleet received $14.7 million from NOAA’s Office of Habitat Conservation to fund the Herring River Restoration Project (HRRP). Francesco Peri, President and CEO at Charybdis Group LLC, uses a network of NexSens data loggers to monitor water level and water quality on the Herring River.
