The centerpiece of the Buffalo, New York parks system and located in the North Buffalo neighborhood. The park was named simply "The Park" by Olmsted; it was later renamed Delaware Park because of its proximity to Delaware Avenue, Buffalo's mansion row. It is divided into two areas: the "Meadow Park" on the east and the "Water Park", with what was originally a lake ("Gala Water"), on the west. The ravine and picnic grove on the south side of the lake comprise a subdivision of the latter. A widening of Scajaquada Creek, which flows westward through the park, is called Hoyt Lake (originally Mirror Lake). The lake was a feature during the Pan-American Exposition. The Scajaquada Expressway bisects the park west to east.
