Roll up your pant legs and meet us at Crawdad Creek on Saturday, May 23 from 10 to 11:30 a.m.

Net and identify the critters you find and discuss their role in the ecosystem. Peer underwater with a scope or examine a magnified pond insect under a lens.

Prepare to bring a change of clothes, proper shoes to wear in the water, etc.

This activity is free with a Nebraska state park vehicle permit.
