We will be tracking emergence of Pale Morning Dun (PMD) mayflies this summer!

Catch the Hatch is one of our Community Science Program’s projects, and we have over 30 volunteers geared up and ready to go for the pilot year. Collectively, we will be visiting sites on Boulder, Left Hand, and North Saint Vrain creeks each day from June 15 through July 15 to capture and identify emerging PMDs. If you would like to learn more about the project and its scientific goals, please visit our project page here.
