Citizen Science

  1. 1.  Enhanced datasets Reliable and engaged Baseline and long-term Local and immediate Leads to Action Photo by Lew Stamp LewStampPhotography.com
  2. 2. Training Citizen Scientists since 1989…… •Water Temperature •Secchi Disk Transparency •Water Color •Qualitative Assessments
  3. 3.  Improved reporting  Since 2008  153 Level 1 QDCs  4 Level 2 QDCs  1 Level 3 QDC On-line data entry  30 active volunteers  16 QDCs  8 with 10+ years QA/QC Protocols  Carl Moore, CLAM Data Coordinator Reliable and Long-Term
  4. 4. Mesotrophic Eutrophic Hypereutrophic SD > 78” 20” - 78” SD < 20earthobservatory.nasa.gov/Features/WaterQuality/water_quality2.php
  5. 5. 0 No Secchi data No Secchi data 0.5Secchi Disk Depth (m) 1 Bars = annual median Dots = monthly mean 1.5 Grass Carp Harvesting Dredging 2 1988 1990 1992 1994 1996 1998 2000 2002 YEAR
  6. 6.  Level 2 data › Transparency › Water temperature › Water color › Quality and lake use  Level 3 data › Temp. / DO profiles › Total nutrients › Total suspended solids › Chlorophyll a
  7. 7. Lake Keepers
  8. 8.  Harmful Algal Blooms (HAB) › Composite samples from shoreline › Collected by Lake Keepers › Evaluation of citizen protocol BSA Environmental Services, Inc. › Phytoplankton identification › Cyanobacteria counts › Microcystin measurements

  10. 10.  30 active lakes › 38 in 2000 › 20 in 2010 SD: 7.92” – 86.38” 2 mesotrophic (> 78”) 13 eutrophic (20”- 78”) 5 hypereutrophic (<20”) Secchi Depth Water Color
  11. 11.  Range: 2 – 7 (greens) › Crystal Lake at 1.7 › Roaming Rock at 8.2 ‘Greener’ with >SD Algal turbidity Secchi Depth Water Color

  18. 18. Algae Bloom Advisory = Identified Public Health Advisory = 6 ppb No Contact Advisory = 20 ppb ohioalgaeinfo.com
  19. 19.  MWCD reservoirs › n = 9 (no Beach City) › 23–68% forested Charles Sampled: Mill Atwood › OLMS: Jun–Sep, bi-weekly Pleasant Leesville Tappan › DOW: 1 summer  Intensive Hill Clendening Compare samples Wills Creek Piedmont › Pleasant Hill Seneca › 2010–11 › DOW: 12, OLMS: 12 samples Compare distributions › Temp/DO profile data Contrast DOW & OLMS data

  21. 21. Similar trends Missing data 30+ d DO < 3 mg/L Divergent profiles> 5 mo
  22. 22.  Eutrophic or hypereutrophic Algal driven turbidity HABs present as severe blooms Toxin health risk low (microcystin) › Level of Algae Bloom Advisory Trends indicated by citizen data
  23. 23.  Charles Mill and Wills Creek? Another HAB monitoring season Test for Cylindrospermopsin toxin
  24. 24. Staff, and volunteers Volunteer cultivation, transparency data, on-line databaseGrant funds Reservoir management, community awarenessMonitoring equipment, water analysis, and staff Fisheries management, program evaluationIn-kind, and staff Algae characterization
