Seney National Wildlife Refuge and the Grand Sable State Forest dominate this Upper Peninsula landscape, where a sophisticated network of 20th-century water management features defines the wetlands. The terrain is crisscrossed by an extensive system of ditches and diversions, including the Holland Ditch, Twomlie Ditch, and Unit No 1 Diversion Ditch, which channel water through the marshlands and into various managed pools like C-3 Pool and Sweeney Pool.
