A Beginner's Guide to Pond Dipping

Why pond dipping is the best introduction to waterside wildlife

There is a moment, just after you lift a net from a quiet corner of a lake or pond, when the water in your tray seems to come alive. A dozen tiny creatures row, wriggle, and paddle through the shallows. For a beginner, pond dipping is the most immediate way to meet the wildlife of a UK lake or pond. It is also a wonderful companion to a waterside walk or a spot of birdwatching. While you wait for a kingfisher to flash past, you can discover an entire small world under your boots. All you need is a net, a tray, and a little patience.

The simple kit that fits in a rucksack

You do not need expensive equipment. A proper pond dipping net with a fine mesh is best, but a clean aquarium net works for a first attempt. Avoid a garden sieve, which is too coarse and damages soft-bodied creatures. For a tray, use a white plastic tray or a shallow ice-cream tub. White makes tiny animals easier to see. Add a magnifying glass, a plastic pipette, a plastic spoon, and a small notebook.

• Footwear: wellies or sturdy waterproof boots. Banks are often muddy and slippery.
• Clothing: long sleeves and trousers to protect against nettles and ticks.
• Safety: a companion, a mobile phone in a dry bag, and hand gel or soap for afterwards.
• Extras: a laminated identification chart, a torch for peering into shaded water, and a spare jar for a close look before release.

Never use glass near the water. Never take a creature home. Everything goes back where it came from.

Where to dip, and how to dip gently

Choose a shallow edge with a flat, safe bank. Avoid deep water, steep sides, and anywhere with nesting birds or spawning fish. If the pond is on private land, always ask permission. On a nature reserve, check the rules first. Many reserves ask you to dip only from a designated platform.

Lower your net at an angle and sweep it through the water in a figure of eight. Do not scrape the bottom, because that stirs up mud and destroys delicate plants and invertebrates. Lift the net smoothly and turn it inside out over your tray. Add just enough pond water to cover the creatures. A little water is better than a lot, as it concentrates the animals and makes them easier to spot. Leave any weed in the tray for a minute. Many creatures cling to it.

Meet the residents: from water boatmen to newt larvae

The first creatures you notice are usually the movers. Water boatmen row with oar-like legs. The lesser water boatman swims the right way up and feeds on algae. The backswimmer swims upside down and can give a small nip, so handle it with a spoon, not fingers. Pond skaters skate on the surface film, sensing vibrations. Diving beetles are glossy and carry a bubble of air under their wings.

Look more closely and the pond reveals its hidden hunters. Dragonfly nymphs are large and dull brown, with a hinged jaw they can shoot forward. Damselfly nymphs are slender and have three leaf-like tails. Caddisfly larvae often live inside a case made of twigs, sand, or leaves. Mayfly nymphs have three tails and plate-like gills along the sides.

On the bottom, you might find water snails such as ramshorn and bladder snails, leeches that ripple through the water, and flatworms that glide like tiny ribbons. In spring and early summer, look for newt larvae. They have feathery gills and grow their front legs first. Frog tadpoles grow their back legs first. Toad tadpoles are small and almost black. A magnifying glass turns a speck into a wonder.

After the dip: record, release, and watch the birds

Keep a simple record. Note the date, the weather, the water temperature if you have a thermometer, and a tally of what you saw. A quick sketch helps you remember. After no more than twenty minutes, return every creature to the exact spot you found it. Tip the tray gently. Rinse your net and tray in pond water, then dry them thoroughly. This check, clean, dry routine helps stop the spread of invasive plants and animals between ponds and lakes.

Once your kit is packed away, sit still for a while. The birds return. A grey heron may stalk the far bank. A little grebe may dive with a soft plop. Swallows and house martins skim the surface for insects. In winter, look for goldeneye and goosander. In summer, listen for the chattering sedge warbler and the metallic call of a reed bunting. Pond dipping and birdwatching are natural partners. One shows you the smallest lives in the water. The other shows you the largest lives above it. Both make a waterside walk unforgettable.
