Brislington Brook.

We are so lucky in Bristol that at the end of the last ice age the sea level was 150 feet, that is 50 metres, lower than it is now. The result is that even very small streams run through very deep valleys, and Brislington Brook is no exception. Steep sides are hard to cultivate, and difficult to build on, so as Bristol expanded the developers usually left them alone. Brislington Brook rises in Hengrove Park, cuts through the village below the church, and then starts to fall very rapidly through Nightingale Valley and past St Annes wood to join the Avon just above Netham Lock.
