Living Under the Water! Kids Program

Carolyn Holmberg Preserve at Rock Creek Farm 2100 S. 104th St., Broomfield

We enjoy watching the many critters that live near and on the water, but what about what lives under the water? Join us as we explore the critters that live in ponds like snails, nymphs, and fish. We will be pond dipping using nets and dissecting plant parts to explore how these amazing plants and animals live under the water. This program is geared toward children ages 6-8, but all are welcome. Registration for most programs begins on the 20th of the month before the event. Registration required. Register Registration is required through Discover Boulder County, Parks & Open Space’s volunteer and event registration system. If you’re new to the system, you'll need to create an account.
