Windmill Pool

Earlswood Lakes is the modern name for three man-made reservoirs which were built in the 1820s at Earlswood in Warwickshire, England, to supply water to the Stratford-upon-Avon Canal. They still supply the canal, and also provide leisure facilities, including sailing, fishing and walking. The northern banks of the lakes form the county boundary with the West Midlands.
