What it’s like
The place. Spring Bay is a very small village on the Illinois side of Peoria Lake, in Woodford County, and Upper Peoria Lake sits in or beside town. Household incomes here are well below the county's, and more people live below the poverty line than many would expect of a lakeside village. Few adults hold a four-year degree, and a typical home costs far less than in much of the country. Winters are cold and snowy, with January the coldest month, and summers turn warm in July, with a fair amount of rain and melted snow through the year.
Work. Residents work mostly in schools, hospitals and social care, with manufacturing, shops and professional and business services close behind. Across Woodford County, some of the largest workplaces are Nucor Steel, Metamora Community Nursing Home and Edeco. Unemployment across the county is lower than a year ago, though the county has fewer jobs than it did the year before. Commutes are of moderate length, and only a small number of people work from home.
Things to do. Upper Peoria Lake lies in or beside town, so water is close at hand. A short drive away are Peoria Zoo and Peoria Lake, and the Woodford State Fish and Wildlife Area offers protected land to walk and watch birds. For a longer outing, Fort Crevecoeur is a fort reached by a longer drive.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Spring Bay’s census tracts, against the rest of the country; all of them together, relatively moderate. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.
From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on Woodford County and the Peoria, IL metro.
