Chalgrove Brook is a chalk stream located in South Oxfordshire, England. [1]
It is a left tributary of the River Thame. It rises in a number of natural springs at the foot of the Chiltern Hills in and near Watlington, and flows in a northwesterly direction for approximately 7 miles (11 km) through Cuxham, Chalgrove, and Stadhampton, before emptying into the Thame near Chiselhampton. [2]
The brook floods occasionally, especially in and downstream of Chalgrove. To relieve this, a man-made conduit was built in Chalgrove, splitting the stream in two. [3]
The stream is home to brown trout, mink, otter and water vole, [3] [4] and possibly also the endangered white-clawed crayfish. [5] As part of the brook's conservation efforts, in 2023 a fish pass was created to circumvent Stadhampton Mill, making available 2 miles (3.2 km) of the brook that was previously impassable to fish.
