It was no tricks, only treats for all of us this Halloween! October 31st brought the end to many of our fisheries monitoring seasons. Every year it is our greatest privilege to work with and mentor young professionals as they dip their feet in the water of the rivers and work we all love!

Scenario: It’s the first day of a new fisheries field season. Your crew leader shows up in an electrofishing boat, both of which are covered in #mayflies. You’re not sure, but there appears to be a faint exclamation point above his head as he invites you along on a side quest. How do you answer?

We had some modifications done to our airboat, so we test drove it on Emiquon today. The wildlife views never disappoint! #ExperienceEmiquon

Happy #EarthDay! Today we began our annual aquatic invertebrate monitoring season. Using a PONAR sampler like a claw machine, we sample the river sediments for inverts that form the base of the food wed. Their sensitivity to pollution also makes them important indicators of our river’s health. #UMRR

We spent the last few days in Rock Island at the Illinois Chapter of the American Fisheries Society meeting. This meeting includes presentations by state management agencies and research personnel, including many students, that help manage the state's aquatic resources for future generations.

This week began our 2-week winter #waterquality monitoring season. We're thankful for our partners at the Chautauqua National Wildlife Refuge and use of their airboat while ours is in the shop. Ice thickness on Tuesday was still around 8 inches in most places, though quickly thawing. #UMRR
