Overview of River Areas
All the rivers which run through South Bristol start life on the Dundry Slopes, just south of the city. The geology of the Dundry Slopes is responsible for our rivers. The upper layer of rock is porous and rain drains easily through it, until it hits the lower layer of rock which is clay and non-porous. At this point the water is forced out of the ground, and there is a line of springs along the Dundry Slopes, which gradually join together to form our rivers.
From east to west, Brislington Brook, the Pigeonhouse Stream, the River Malago and Colliter's Brook, run down through South Bristol and out into the River Avon and the New Cut. We count the Avon New Cut as one of our rivers too, and a much valued one with its wonderful history and wildlife.
