The River Chess is historically very important. It was instrumental in the founding of the towns and villages in the valley, providing food and water and driving, at one time, some 13 water mills along its course.

As a consequence of activities such as agricultural cultivation, ornamental landscaping, industry and urban development, the river has been extensively modified over many years and became quite polluted at one time.  Although water quality has improved in recent years, demand for water in the area has increased to a point where the river’s upper reaches are now particularly vulnerable to drying up during drought.

Despite these issues the R. Chess is perhaps the most unspoilt of all the Chilterns’ chalk streams and is an extremely valuable habitat for wildlife. It is one of the strongholds in the Chilterns for the water vole and supports fish such as trout and grayling, along with an abundance ofinsect species such as the banded demoiselle and blue-winged olive.  It also provides valuable sanctuary for bird species such as kingfisher, water rail, green sandpiper and even the beautiful osprey.

One of the main tributaries is the  Vale Brook which is culverted under Chesham town centre.
