[1] The Trust for Public Land ranks one part of Mill Creek as the 142nd largest park located within the limits of a US city.

[3] Once the land was secured, Rogers framed and promoted what he called the "Township Park Improvement Law".

[7] The same year that the park opened, the Mahoning County commissioners issued bonds to pay for the parkland, and Rogers purchased $25,000 of them, with the understanding that they would be the last ones paid.

The men cut trails, established drives, restored Pioneer Pavilion (a renovated factory building that was the oldest structure in the park) and built Lake Cohasset Dam".

Lake Glacier was created in 1906 by the damming of Mill Creek at the "narrows" as it approached the Mahoning River.

Mill Creek meandered through this shallow valley making it a suitable site for a man-made lake.
