The brook in the late 19th century which flows into the River Anton (right). The largely suburban town of Andover on right has multiplied in size, taking up the east half of its parish shown and land to the north.
Toponymy
The brook is believed to have been called the Ann, or Anna.[3] The name aqua de Anne is found in the Close Rolls in 1228.[4]
Tasker "Little Giant" traction engine and log trailer
in 1813, the brothers Robert and William Tasker set up the Waterloo Ironworks in the Anna Valley at Upper Clatford, using a waterwheel driven by the brook to power the forge. They specialised in making agricultural equipment, progressing to the manufacture of steam traction engines from 1865. There were four conventional watermills on the brook: Upper Mill at Monxton,[5] Upper Mill at Abbotts Ann,[6] Abbotts Ann Mill[7] and Sarsons Mill at Amport.[8]
Water quality
The Environment Agency measures 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 invertebrates, angiosperms and fish. Chemical status, which compares the concentrations of various chemicals against known safe concentrations, is rated good or fail.[9]
