Water velocities were measured around water plants in a chalk stream. Low velocities (<100 mm.s−1) were associated with stands of plants while faster flowing water (>500 mm.s−1) was found in open water and above weed beds. An indirect method of estimating mean water velocity through weed beds, using discharge measurements, revealed velocities between 40 and 140 mm.s−1, while open water velocities ranged between 200 and 370 mm.s−1. The significance of the velocities is discussed.
