Their close symbiosis with chlorophyllic microalgae gives them their snot-green color. To read more about these freshwater residents, check out this fun and informative article:

2022 Mid-Season Volunteer Monitoring Update
07/01/2022 - We can't believe the summer is halfway over! As we dive in to Lake Appreciation Month and the midway point of our 2022 volunteer monitoring season, we're here with some mid-season updates, reminders, and more.
First, some "by the numbers" for our volunteer lake monitoring program:
- 19 Temperature/Dissolved Oxygen profiles recorded
- 136 Secchi entries
- 58 sets of Expanded Monitoring samples collected
A few important details to keep in mind for our volunteers:
- Always take off those hats and sunglasses when collecting secchi readings!
- Ship water samples Monday-Wednesday so they're not sitting over the weekend, or for too long at the post office
- If you noticed 2021 data missing and it has not been corrected, please email or give us a call!
- Enter those secchi readings to the NALMS Secchi Dip-In in addition to sending them to us! You can also enter readings to this program all year-round:
Lastly, let us know about your lake association/lake group events! We can post these on our website and share them to our social media accounts. Give us a follow if you haven't already!
