New York's access file puts 1 public site on the Seneca River — 1 launch, spread over the counties it runs through. 4 blocks of public land front the Seneca River, and 1.7 of its 13.8 mapped miles run through them.
| Site | Type | River mile | County |
|---|---|---|---|
| Seneca River at Lysander | boat launch | 7.0 | Onondaga |
0 walk-in, 1 launch, 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.
