Peppershill Brook


The Peppershill Brook starts below Chilton where the Chilton sewage treatment works discharges, the brook then flows through Peppershill before meeting the Shabbington Brook and then the main river Thame.

The classification for Peppershill and Shabbington Brooks is merged together, therefore this section is a reflection of both brooks. In 2015, the Environment Agency classified the Peppershill and Shabbington Brooks as “moderate”, meeting its 2015 objective. Unfortunately these brooks are largely under-surveyed as there is no data on fish, invertebrates or macrophytes. In 2014, there was no physio-chemical data either (phosphate, ammonia, dissolved oxygen, pH, temperature) which gave the brooks a default classification of “good” status. Since then there has been physio-chemical surveys which have shown that the phosphate levels are at “moderate” and dissolved oxygen is at “poor”. This highlights the need for further data to allow us to fully understand our catchment. There are currently no 2027 targets for these brooks, but we hope to do some further investigation to find out more about them.

Small Waters

The river isn’t the only water that we are concerned with. There are multiple small waters including ponds, ditches and steams. All of which are highlighted on the map below.perppershill-brook-small-waters
