The Department of Environmental Protection (DEP) conducts several types of physical and chemical monitoring in the County's waterways. Use the links below to learn more.
Stream Habitat Assessment
Assessment of streamside and instream habitat, which correlates with water quality conditions.
Stream Flow Monitoring
Measurement of steam flow volume and rate of flow.
Stream Temperature Monitoring
Continuous measurement of summer stream temperatures.
Stream Channel Surveying
Measurement of the physical structure of stream channels, which correlates with water quality conditions.
Physical Chemistry Monitoring
The following physical chemistry data are collected at every stream monitoring site:
- Dissolved oxygen (DO), the amount of oxygen in the water that is available to biological life, including benthic macroinvertebrates and fish
- Water temperature
- Air temperature
