The Bear and Wendover Brooks are the most urban brooks in the catchment, they flow through the centre of Aylesbury. The Wendover Brook begins in Wendover, flows through Weston Turville and meets the other streams just outside Aston Clinton. When the brooks meet, they flow through Aylesbury before meeting the Stoke Brook and the Main River below the Aylesbury sewage treatment works. There are no sewage treatment works on the brook itself, but it does suffer from road run-off. Overall, the land-use varies from urban, arable and pasture. The significant amount of urban landscape comes with its own problems, such as litter and fly tipping. These brooks are the link between the Thame Catchment and the Grand Union Canal.
Flooding has been associated with these brooks in the most urban sections, there are projects being developed by the Buckinghamshire County Council and other partners, which will go some way to reducing the impacts.
In 2015, the Environment Agency classified the Bear and Wendover Brooks as moderate (meeting its 2015 target). The moderate status is due to a moderate a moderate phosphate and invertebrate classification. Fish and other water quality analysis has come back as high. Unlike many of the other waterbodies in the Thame Catchment, the phosphate levels are targeted to be at good status by 2027, along with invertebrates. It is likely that the overall target for this waterbody will be good, but this has still not been confirmed.
You can find out more about the classification of rivers in our catchment by using the Environment Agency’s Catchment Data Explorer.
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.
More recently we have started to receive regular water quality monitoring results from our volunteers, but we do not have full coverage as this is such an extensive waterbody.
We would love to extend our volunteer monitoring in this area, particularly riverfly and water quality monitoring, you can find out more about our volunteer monitoring and how you could get involved in monitoring yourself here.
There are currently no groups that are working specifically on the Bear or Wendover Brook. If you would like to get involved by starting a local group in your area, then please get in touch.
