About the River Thame

The Thame Catchment

Rising in tiny headwaters to the east of Aylesbury the Thame then curls around the western edge of the town before flowing roughly south-west, into Oxfordshire past Thame and Wheatley and on to its confluence with the River Thames just below Dorchester-on-Thames.

The Thame catchment is 682km2 with 340km length of waterway and has a population of 183, 000 people and 35 sewage treatment works, one of the highest concentrations of in any of the River Thames catchment areas.

The River Thame catchment straddles Buckinghamshire & Oxfordshire (and also touches Hertfordshire near Tring), and encompasses only two significant towns (Aylesbury and Thame). Land use is predominantly agricultural with a few protected areas within its valley including a small number of SSSI’s along the Chilterns escarpment and the Shabbington wood complex in the west.

There are multiple conservation organisations that work within the catchment, but very few focus on the river itself.
