[4] The damming of the Mohawk River for the creation of the New York State Barge Canal in 1915 caused the mouth of the Lisha Kill to become a back bay and this required the building of a bridge to connect Ferry Road to the "mainland".

[2] To the north and east of Niska Isle is the Mohawk River, which separates it from the hamlet of Vischer Ferry in Saratoga County.

[5] The only land access to Niska Isle is by way of a bridge that carries Ferry Road over an abandoned railroad bed (now the Mohawk Hudson Hike/Bike Trail) and the back bay.

[2] A small parking area is at the end of Ferry Road at the river's edge and allows for access for fishing and a boat launch.

Fish off Niska Isle include bass, pike, muskie, panfish, and 20–30 pounder carp.
