New York's access file puts 2 public sites on the Allegheny River — 2 walk-in sites, spread over the counties it runs through. 2 blocks of public land front the Allegheny River, and 0.5 of its 10.3 mapped miles run through them.
| Site | Type | River mile | County |
|---|---|---|---|
| Allegheny River at Portville | walk in | 8.4 | Cattaraugus |
| Allegheny River at Olean | walk in | 3.6 | Cattaraugus |
2 walk-in, 0 launches, from New York's own access file. River mile is measured up from the mouth along this river's drawn axis.
Ownership from PAD-US as the state publishes it. Where a block has its own page, the name links to it. The river miles are how far this river's drawn axis runs inside each block, measured here; the acreage is the whole unit's, most of which is nowhere near this water. "Restricted access" and "access unrecorded" are PAD-US's own words for the block, and neither one means open — check before you park.
