Designed and installed in 1905 by John Morris, this is an artificial lake created by damming the East Brook, which naturally flows through the Arboretum. The idea may have come from the popular 18th-century landscape design style of the English romantic landscape which often included a classical temple reflected at water’s edge. Files from that time period indicate the Morrises purchased a pair of swans in 1923, for $82.50. Mute Swans mature at four years and usually mate for life. Females lay an average of six eggs in the spring at two-day intervals. Cygnets, or baby swans, hatch after 35 days and can swim after one day. Adults share rearing duties and are extremely protective – they may even injure a person if provoked.
