1. Fixed Interval Monitoring (FIM): Grab samples and field data collected monthly at specific stream monitoring sites on a fixed interval, such as the 10th day of every month, regardless of weather conditions.
2. In-Stream Storm Water Monitoring (ISM): Flow weighted composite samples and field data collected monthly at specific stream monitoring sites during storm water flows using automated samplers.
3. Lake Monitoring: Grab samples and field data collected monthly at specific lake monitoring sites during base flow conditions.
4. BMP Monitoring: Flow weighted composite samples and field data collected monthly at the influent and effluent of specific structural BMPs during storm water flows using automated samplers.
5. Biological Monitoring: Benthic macroinvertebrate and fish samples collected annually at specific stream monitoring sites.
6. Continuous Automated Monitoring (CMANN): Data collected hourly for pH, temperature, dissolved oxygen, conductivity and turbidity using remote automated monitoring equipment that transfers data to a website via modems. Get CMANN data.
