Haseley Brook

Description

The Haseley Brook starts in Adwell and meets the main River Thame after crossing underneath Stadhampton Road. A few very small streams run in to the brook all the way across. The main land-uses include pasture and arable fields, we are looking to do further walkovers of this brook to understand land-use more. The Chalgrove sewage treatment works discharges in to one of the streams entering Haseley Brook (this is the main stream that is visible on the map), as Chalgrove is a growing area, this works is under increasing pressure.

In 2015 the Environment Agency classified the Haseley Brook as moderate, based on multiple factors. Water quality along the Haseley Brook is surprisingly classified as high or good for all measurable factors (under Water Framework Directive), except for phosphate which is classified as poor, likely to be as a direct result of the sewage treatment works impact and other impacts from agriculture. The Haseley Brook was targeted to reach “moderate” status by 2015 (including phosphate). On a cost-benefit analysis it is currently considered not feasible to improve the phosphate issue to anything more than “moderate”, but this target has still been missed, with only a status of “poor” reached. We hope that this may change in the future as investment is put into the sewage treatment works and catchment sensitive farming.

Map

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.haseley-brook-small-waters

Projects

Surveys

Unfortunately we don’t have any volunteers monitoring this brook. You can find out more about our volunteers monitoring and how you could get involved in monitoring yourself here.

Other Groups

There are currently no groups that are working specifically on the Haseley Brook. If you would like to get involved by starting a local group in your area, then please get in touch.
