2023 Map of Steamburg

About this map

The Allegheny Reservoir dominates the landscape of this southern Cattaraugus County region, where the Allegheny River valley was transformed into a massive water body. The settlement of Steamburg remains situated at the northern edge, while the site of Onoville marks the southwestern reaches near the Pennsylvania border. This rugged terrain is characterized by numerous hollows and steep elevations such as Johnny Watt Hill, Round Top, and High Peak. Traces of the older landscape persist in the upland cemetery at Steamburg Cem and the Old Town Cem near the reservoir's eastern bank. Local history is etched into the names of the drainage network, from Sawmill Run and Hotchkiss Run to the eastern boundaries of Allegany State Park. This modern survey records the enduring topography of the Allegheny highlands, showing how the reservoir has reshaped the traditional valley settlements.
