Catch the Hatch
Mayflies are important indicators of watershed health and are threatened by pollution and climate change. Join our team this summer from June 15- July 15. Record data on mayfly emergence and creek temperature at specific creek locations in the St. Vrain sub-basin. Becoming a data catcher means you will train with scientists and make observations on your own schedule! Learn more about project details here.

Catch the Hatch
Mayflies are important indicators of watershed health and are threatened by pollution and climate change. Join our team this summer from June 15- July 15. Record data on mayfly emergence and creek temperature at three creek locations in the St. Vrain sub-basin. Becoming a data catcher means you will train with scientists and make observations on your own schedule! Learn more about project details here.

Hatch charts from previous seasons
Catch the Hatch aims to track Pale Morning Dun mayfly emergence during their peak emergence window (June 15 through July 15) in relationship to environmental variables, such as flow and creek temperature, from year to year.
Take a look at the hatch charts below. Do you see any differences in the timing of emergence observations or the associated creek temperature or flow from year to year?
Left Hand Watershed Center’s Community Science Program aims to engage Front Range communities in place-based learning and scientific data collection about watershed health. Please learn more about our Community Science Plan or help support future projects!
