Resource managers rely on accurate water data when assessing the health and longevity of water supplies. In-Situ^® instrumentation can be used for a variety of surface water applications from long-term supply management to quick quantity and quality checks.

Flood Control and Monitoring

Log water level data and receive alarm notifications during an event by using Level TROLL^® instruments, the Con TROLL PRO System, and a TROLL^® Link Telemetry System.

Application Note: Tidally Influenced New Orleans Canal Network Benefits from Accurate Water Level Data

Lake and Reservoir Monitoring

Track reservoir levels, monitor dam seepage loss, evaluate water quality, and conduct profiling studies with In-Situ instruments.

River and Stream Gaging

Collect water level data over extended periods. Use data to track impacts of discharge, rainfall, and runoff.

River Crest Stage Gaging

Determine and track high water levels or flood crests of rivers and streams with Level TROLL instruments.

Stormwater Monitoring

Collect data on the amount and rate of stormwater runoff and identify sources and patterns of pollution loading by using TROLL^® 9500 and Level TROLL instruments.
