River Dipping at Cassiobury Park

Join us for a hands-on family session exploring the fascinating wildlife of the River Gade. With guidance from our staff, you’ll step into a shallow section of the river and try river dipping, to discover the amazing creatures living beneath the surface.

We’ll identify what we catch and learn about the insects, invertebrates, and other wildlife that live in chalk streams. You’ll discover how these tiny creatures act as indicators of good water quality, and why healthy rivers are so important for wildlife.

As we explore, we’ll also be on the look out for the birds and insects that depend on the river, such as waterfowl, dragonflies, damselflies, and riverflies. You may even spot our resident kingfisher.

This session is a great opportunity to explore nature up close, and learn practical ways you can help protect rivers and wildlife. We’ll also share ideas for simple actions you can take for nature, from saving water at home to getting involved with local community groups.

What to bring:

• Wellies or waterproof boots
• A change of shoes
• Clothes you don’t mind getting a bit wet

Important information:

• For ages 6 and above
• 1 parent/guardian per 2 children is required.
• If the weather is poor, the session will move indoors at the Hub where we will continue learning about river wildlife and conservation.

Come and discover just how rich in life our local river can be when you take the time to explore it.

Herts Rivers Week 2026 is a county-wide celebration of our chalk rivers through events and activities for all ages. It is also a call to action designed to help people understand the value of chalk rivers - and the role we all play in protecting them.
