Overview of Michigan’s Surface Water Monitoring Program and Water Quality Trends

By: Gary Kohlhepp and Ralph Bednarz, DEQ-Water Bureau


Overview of michigan s surface water monitoring program and water quality trends

Monitoring Strategy and Water Quality Trends

  • 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


Overview of michigan s surface water monitoring program and water quality trends

Four Monitoring Goals and Water Quality Trends

  • 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 Quality Monitoring Program Elements Michigan Initiative

  • Water Chemistry

  • Sediment Chemistry

  • Fish Contaminants

  • Biological Integrity & Physical Habitat

  • Wildlife Contaminants

  • Beach Monitoring

  • Inland Lake Quality

  • Volunteer Monitoring

  • Stream Flow


Overview of michigan s surface water monitoring program and water quality trends

Water Chemistry Michigan Initiative

  • 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)


Overview of michigan s surface water monitoring program and water quality trends

Sediment Chemistry – Inland Lake Trends Michigan Initiative

  • 35-40 lakes to be sampled

  • 27 lakes sampled through 2004

  • Provides long-term record of contaminants

Overview of michigan s surface water monitoring program and water quality trends

Lake Water Quality Assessment Michigan Initiative

  • 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


Overview of michigan s surface water monitoring program and water quality trends

Volunteer Monitoring Michigan Initiative

  • 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


Overview of michigan s surface water monitoring program and water quality trends

Objectives Michigan Initiative

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
Cooperative Lakes Monitoring Program Michigan Initiative(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)


Clmp quality data
CLMP Quality Data Michigan Initiative

  • Detailed procedures

  • Comprehensive training

  • Replicate sampling

  • DEQ side-by-side sampling
