Etymology
From
Alternatively the Old Welsh /mixn/ for "bog" is suggested by the earliest-known form, from 862, Mycendefr, not relatively prevalent due to the gradient and alkaline water.[3]
Attributes
It is essentially fed by very close chalk aquifers, likewise to its continuation the Test, a highly abundant watercourse in Europe for large trout. It includes two trout farms, at the otherwise almost wholly green locality of Bransbury, and at Difford, north of Barton Stacey. The watermill at Weston Colley is a Grade II listed building/.[4] The mill at Bransbury is also Grade II listed.[5]
Water quality
The Environment Agency measures the water quality of the river systems in England. Each is given an overall ecological status, which may be one of five levels: high, good, moderate, poor and bad. There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of
