Stream water quality and quantity is hugely affected by the amount of rain falling on the catchment. 

Short bursts of very heavy rain have proved particularly problematic; run off from our roads, roofs and other impermeable surfaces carries high levels of pollutants to the stream, and stream banks are regularly overtopped, dramatically increasing the likelihood of local flooding.

In an attempt to test the various theories of climate change locally, and to predict where SUDS might best be implemented, we use meteorological records collected daily since 1934 by Borough of Poole Leisure Services.
