1 Oakland County Healthy Lakes Initiative A partnership with the Cooperative Lakes Monitoring Program Training Day May 5, 2018

2 Today s Agenda! 9:00-10:15 Welcome! Transparency (Secchi Disk) Spring/Summer Phosphorus 10:15-12:15 pm Exotic Aquatic Plant Watch 12:15-12:30 pm Break for Grabbing Food and Leaving 12:30-1:30pm Optional: Score the Shore 2:00 pm Everyone out!

3 The Self-Help Legacy 1974: Secchi disk - second oldest program in country : added spring overturn total phosphorus, late-summer total phosphorus and summer chlorophyll. 2000: added Dissolved oxygen/temperature. 2001: added Aquatic Plant Surveys 2011: added Exotic Aquatic Plants 2016: added Score the Shore

4 Who s Involved? State of Michigan volunteer monitoring umbrella. MiCorps for short. Part of MiCorps; Michigan s volunteer inland lake monitoring program. The CLMP. Oakland County: Your tax dollars at work!

5 MiCorps Staff CLMP Trainers: Dr. Jo Latimore, Michigan State University Dr. Paul Steen, Huron River Watershed Council Erick Elgin, Michigan State University Extension

6 MiCorps Staff Enrollment & Equipment: Jean Roth, Michigan Lake and Stream Associations

7 MiCorps Staff Niklas Krantz Lake Monitoring Intern Your primary contact throughout the summer! him! His job is to help you. because he will rarely be at his desk to pick up the phone.

8 Questions Today? Questions on the program or procedures: Hold to the end of this presentation Please save questions specific to your lake. Lake specific questions or questions that don t get answered today: Please nkrantz@hrwc.org

9 CLMP Monitoring: Measure Status and Trends of: Trophic State (nutrient load; affects algae growth, water turbidity) Rooted aquatic plants Invasive plants Shoreline conditions

10 CLMP Efforts! 303 in 2018, 260 in 2017, 241 in 2016

11 Why Monitor? To inform statewide and local management decisions. To increase education and awareness of Michigan citizens on lake issues.

12 Want to make a presentation for your lake association? Use this as a base: micorps.net Lake Monitoring CLMP Documents Create Your Own Data Presentation Spread the word Fact Sheets are available for each CLMP parameter

13 Training Videos and Documents Procedures, schedules, data forms Videos for most of the parameters micorps.net Lake Monitoring CLMP Documents

14 Some other resources to be aware of CLMP Manual- Read procedures section once a year and keep handy as a reference (will come in mail) Quick-reference procedures bring them out on the boat with you and use it as a checklist.

15 Thank you to all the volunteers who make this program a success!

16 COOPERATIVE LAKES MONITORING PROGRAM TRAINING FOR Secchi Disk Transparency and Total Phosphorus

17 Transparency Secchi disk measurements Evenly spaced monitoring through May 14-Sept 16. *At least 8 measurements* Seasonal variability

19 Secchi Disk Measurement

20 Where to monitor? Lake Sampling Site (Field ID) Number Listing at micorps.net Lake Monitoring CLMP Documents

21

22 Secchi Disk Measurement 1. Slowly lower disk until it disappears from view

23 Secchi Disk Measurement 2. Slowly raise disk until it reappears

24 Secchi Disk Measurement 3. The official measurement is the average of the 2 depths.

25 1. Don t use sunglasses!

26 2. Pick the shadow! Yes! No! Yes Yes! No!

27 3. Be consistent in weather and timing! Yes

28 8 Measurements Required across whole summer: Lakes change over time! Seasonal Succession of Lake Algae in a Mesotrophic Lake Abunance Winter Spring Summer Fall Winter Credit: Water on the Web

38 COOPERATIVE LAKES MONITORING PROGRAM TRAINING FOR Total Phosphorus

39 What you get in the mail Monitoring instructions (if you asked for it) Sampling and sample turn-in schedule and locations (if you asked for it) Data form Bottle labels (3) Two 250ml bottles with caps on

40 Other materials needed: Cooler bag, ice pack, zip lock baggies of different sizes, a pencil/sharpee

41 Spring Overturn Within 14 days after ice-out (March/April/May) Volunteer determines ice-out Surface grab sample Representative of whole lake

42 Summer Stratification Early fall Take the sample SEPTEMBER (Aug. - Sept.) Surface grab sample Indicates the phosphorus available to plants/algae in the growing season.

43 SAMPLE TURN IN FROZEN SAMPLE Two Turn-In Locations 1.DEQ Office, Donald Court, Warren, MI , 9-12 am 2. HERE 8-10 am. Dates Spring P: Turn in June 19 Summer P: Turn in September 25

44

45 Phosphorus Labels.. Pencil or sharpee

46 Rinse Bottle Twice

47 Surface Grab Sample

48 Pour water out until bottle is filled to here to avoid cracking the bottle when frozen.

49

50 Datasheet goes into its own baggie and then into the baggie with the samples.

51

52

53 Freezer Storage until Turn-in Date

54

55 Common Reasons for Sample Rejection Sample collected at the wrong time Especially for Summer P samples collected more than a week outside the assigned interval will be rejected Wrong bottles used We ONLY accept samples in the sterile bottles we send you Incorrect delivery If you forget to turn your samples to the proper location on the assigned date, that can cause problems. CONTACT US for instructions on safe shipping. Unexpected shipments will thaw and be rejected. Cracked bottles/caps Be sure to leave headroom in the bottle for expansion

56 There is a data entry component for Phosphorus, too.
