The original Nassau record combines Jack's Corner near a Route 20 bridge and Beaver Cotton Mill near a dam and bridge. Their old visitor reports are preserved separately from current planning advice. A parking lot, bridge or overlook is not proof that its adjacent bank is open for swimming.
Hudson Taconic Lands identifies Kinderhook Creek Preserve at 300 Martha Hicks Road, East Nassau, with a marked trail network and shoreline recreation. It is a separate property, not a replacement name for Jack's Corner or Beaver Cotton Mill. The village community page describes the preserve's recreation; neither source verifies the two archived swimming approaches.
For a preserve visit, use its manager's directions and current rules. For either archived stop, establish ownership, allowed parking and the particular water use independently. Do not descend beside a bridge abutment or enter a dam-base ravine from historical instructions alone.
Usable swings, free admission, safe depth, a family-friendly beach and a single navigation pin have not been established for these two stops. The old August 2012 verification language is historical evidence, not a fresh inspection. Plan an independently confirmed outing if the intended entrance cannot be resolved.
Identify Jack's Corner or Beaver Cotton Mill separately and confirm the exact current manager and authorized approach before travel. Do not use archived under-bridge or dam-base paths as present swimming directions. Kinderhook Creek Preserve at 300 Martha Hicks Road is a separate destination.
Jack's Corner and Beaver Cotton Mill remain separate historical entries with current swimming permission and lawful parking unresolved. Managed Kinderhook Creek Preserve guidance does not establish permission at either archived stop.
Confirm the entrance, parking arrangements, and legal access with the land manager. A map pin does not establish a public right of access. Follow posted routes and never block gates or driveways.
