Wetland Restoration - Silver Lake

Project Overview


The Silver Lake Wetlands are unique and complex. An ancient glacial kettle lake surrounded by hills of gravel soil deposits has existed since shortly after the Wisconsinan Glacier retreated some 15,000 years ago.

One of Ohio's best examples of a freshwater fen is located on the northwestern side of the lake. In spite of drainage attempts over the last century, the lake and fen maintain their integrity.

To aid in the understanding and preservation of the existing wetlands and fens and the restoration of the degraded marshes and wet meadows, an automated hydrologic monitoring system was installed at Silver Lake.

System Description


At various locations throughout the wetlands, NexSens radio telemetry, YSI 600 LS multi-parameter sondes with temperature, conductivity, and water level sensors, and RM Young tipping bucket rain gauges were installed.

From each location, data is collected and transmitted via a license free, spread spectrum radio to a nearby farm, where a NexSens radio/modem is connected to a telephone line. On a periodic schedule, a computer calls to the remote project site, collects the data, and posts it to a WQData.com datacenter.

Researchers at Miami County Parks, University of Dayton, Wright State University, and Ohio EPA all have access to this data via the Internet, aiding in the research, understanding, and preservation of the wetlands.

Site 3 includes a NexSens 4100-iSIC radio data logger, rain gauge and temperature, conductivity and water level sensors. Site 2 includes 4100-iSIC radio data logger and a YSI 6600 EDS to monitor the wetland outflow and transmit data in real-time. 
Temperature, conductivity, and water level sensors are installed in shallow groundwater wells and wired to the telemetry poles. A NexSens engineer prepares to install Site 3 monitoring well. 
NexSens engineers complete the monitoring well installation. Site 1 is located on a raised fen 2 miles from the base station radio. Data is transmitted in real-time with the 4100-iSIC. 
NexSens engineers complete a monitoring well installation. A YSI 600 temperature, conductivity, and level sensor is installed. A YSI 6600 EDS measures the water quality of the outflow from Silver Lake wetland.
