Unattended Death and Biohazard Cleanup in Seneca, WI

Seneca is a town in Crawford County in the Driftless Area of southwestern Wisconsin, a region of ridges, ravines, and abrupt bluffs that glaciers never flattened.

The town's population was 932 at the 2020 census; at the 2000 census it had 893 people living in 311 households.

Seneca is a big town by area — 65.5 square miles — and about 6.9 square miles of it, or 10.5%, is water, because the Mississippi River runs along its western edge and cuts fractional sections into its survey townships.

The town's ridges drain east toward the Kickapoo River and west toward the Mississippi River, and its valleys of rich black loam have long been prized for corn and vegetables while the ridges suit wheat and other grains.

The unincorporated community of Seneca, which shares the town's name, sits on Wisconsin Highway 27 about 4 miles south-southwest of Mount Sterling, at an elevation of about 1,253 feet, and has its own post office with ZIP code 54654.

The community of Seneca is home to the Seneca Area School District and Seneca High School, a small rural high school on Main Street serving fewer than 100 students, as well as St. Patrick's Catholic Church.

Johnson's One Stop, a general store founded in 1937 that sells groceries, hardware, farm supplies, and building materials, has been a Seneca landmark for generations.

Seneca lies in Crawford County, whose seat is Prairie du Chien, one of Wisconsin's oldest communities, and the county's Mississippi River shoreline is part of the Upper Mississippi River National Wildlife and Fish Refuge.
