Monitoring Strategy
• Completed in January 1997
• Identified a comprehensive list of monitoring activities with cost estimates
• Implementation primarily through grants and contracts
• Updated in 2004/2005 per EPA requirements
• Includes sections on objectives, study design, indicators, quality assurance, data analysis, data management, reporting, program review, and existing/needed infrastructure

Four Monitoring Goals
• Assess the current status and condition of individual waterbodies and determine whether MI Water Quality Standards are being met
• Measure temporal and spatial water quality trends
• Provide data to support DEQ water quality protection programs and evaluate their effectiveness
• Detect new and emerging water quality problems

Water Chemistry
•5-year basin surveys
•Fixed station trends
• Statewide random sampling
•CREP monitoring, TMDLs, other special studies (esp. non-point source effectiveness)
•Local water quality monitoring and emerging issue monitoring grants ($200,000 each)

Lake Water Quality Assessment
• Re-establish LWQA monitoring program – formerly implemented via Clean Water Act – Clean Lakes Program
• Work with USGS to re-establish LWQA monitoring
• USGS and MSU are evaluating satellite technology for regional and statewide lake water quality assessment
![Page 24: Overview of Michigan’s Surface Water Monitoring Program and Water Quality Trends By: Gary Kohlhepp and Ralph Bednarz, DEQ-Water Bureau.](https://reader035.fdocuments.in/reader035/viewer/2022062511/551aaffd550346856e8b4de5/html5/thumbnails/24.jpg)

Volunteer Monitoring
• FY98 through FY05: 33 grants awarded totaling $265,000
• Michigan Clean Water Corps was established in 2003
• Includes stream/river and inland lake volunteers
• www.micorps.net
• DEQ uses data as a “screening tool” to identify sites for follow-up assessment
![Page 26: Overview of Michigan’s Surface Water Monitoring Program and Water Quality Trends By: Gary Kohlhepp and Ralph Bednarz, DEQ-Water Bureau.](https://reader035.fdocuments.in/reader035/viewer/2022062511/551aaffd550346856e8b4de5/html5/thumbnails/26.jpg)
Objectives
Collect data that can be used by DEQ as “screening tools”.
Reach goal of 80% coverage
Assist DEQ in prioritizing sites
Increase public awareness and involvement in protection and surveillance of rivers and streams.

Cooperative Lakes Monitoring Program (The Self-Help Legacy)
• Program began in 1974 with water clarity (Secchi disk) monitoring – second oldest program in country
• Current focus on trophic state indicators• water clarity (228 lakes)• total phosphorus
• spring overturn (196 lakes)• late-summer stratification (206 lakes)
• chlorophyll a (121 lakes)• dissolved oxygen and temperature (53 lakes)• aquatic plant ID and mapping (5 lakes)
