Here is another interesting old Cleveland stream that is no longer extant. According to the 1873 Stringer's Map of Cleveland and Suburbs (http://www.railsandtrails.com/Cleveland/index.html), Spring Brook was a tributary to Doan Brook. It no longer flows above ground. Its source was located between Bolton (East 89th) and Oakdale Streets (East 93rd), south of Cedar. When Spring Brook crossed Euclid east of Brookfield (East 87th), it formed a lagoon just to the north of Euclid (similar to the Giddings Brook lagoon on the south side of Euclid at Giddings Street or East 71st). From there it flowed west toward Crawford Road and then bent northeast running south of Hough and joined Doan Brook just east of the intersection of Hough Avenue and Ansel Road.
