No site in New York's access file falls on Champlin Creek, so the way in is public ground and road crossings rather than a marked landing. 4 blocks of public land front Champlin Creek, and 0.9 of its 4.7 mapped miles run through them.
Brookwood Hall Park — local holder not recorded, 0.4 mi of this river, 47 acres in all
Town Of Islip Land — city land, 0.24 mi of this river, 1,067 acres in all, access unrecorded
Beaver Dam Park - Islip Owls — city land, 0.16 mi of this river, 4 acres in all
Seatuck National Wildlife Refuge — U.S. Fish and Wildlife Service, 0.09 mi of this river, 211 acres in all, restricted access
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.
