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.

Microcystin, one of several toxins produced by the cyanobacteria that form harmful algal blooms (HABs), has become a popular topic of lake research as the human health impacts of HABs become better understood. Stone Lab is one of the leading groups in algal bloom research on Lake Erie and other lakes in Ohio. 
 
For more than 100 years, Stone Lab has conducted biology research and provided science education and outreach to the region. Over the years, thousands of individuals of varying ages have learned from the resources Stone Lab provides. 
 
Stone Lab’s Research Coordinator and Senior Researcher, Justin Chaffin, learned of Stone Lab while an undergraduate student at Bowling Green State University Fireland Campus.
Read MoreFrom Assessment to Angler: Continual Research Ensures Lake Erie Remains a Beacon of Freshwater Fishing
Lake Erie is well known for its abundant recreational fishing. Anglers come from across the country to try their luck at the “walleye capital of the world” and search for other freshwater species, such as bass, perch, and steelhead trout. 
 
 As one of the world’s largest freshwater fisheries, much effort is made behind the scenes to maintain fishing opportunities for visitors to enjoy year after year, efforts that often go unnoticed by the public. 
 
 One of the lake's most important economic and tourism centers is the city of Sandusky, home to the Sandusky Fisheries Research Station . As part of the Ohio Division of Wildlife, the unit serves as a base for assessing fish populations and managing harvest with partner agencies from around Lake Erie.
