In the early 1960’s workmen conducting excavations for new streets unearthed an old Adena burial mound containing two skeletons and the remains of tools at what is now the corner of Yaronia and Wynding Drives. In the early 1800’s, President John Adams granted John Rathbone 4,000 acres of land in the Adena Brook watershed for services in the Revolutionary War. Congress authorized land grants on June 1, 1796. John Rathbone sold most of it off in parcels. Adena Brook is an intermittent stream and has been since area residents can remember. However, it used to sustain deep pools where schools of fish survived during periods of dry weather. Adena Brook is over 2 miles long and has a drainage area of 3.5 square miles. It drops 69 feet per mile.
EPA water quality assessments are based on the Chemical, Physical, and Biological Integrity of the river. In 1999, Adena Brook was found to be non-attaining as a Warm Water Habitat. This tributary has had its flow altered in the past, and Sanitary Sewer Overflows contribute to its high bacteria counts and low dissolved oxygen. Sanitary Sewer Overflows flow into Adena Brook. Manholes at Pauline and Atwood Terrace; Northridge and Atwood Terrace; and east of Indianola Avenue. These discharges occur when sewer levels fill a manhole-type structure to a certain elevation and the structure overflows in order to relieve pressure on the sewer system. The Adena Brook watershed has a high concentration of impervious surfaces and an aging sewer system. FLOW would recommend the installation of rain gardens in the area to slow the flow of stormwater from impervious surfaces and possibly returning the stream to a more natural flow pattern.
