Did you know
  • Wilmington's backup reservoirs became the contaminated ones: the Burtonville pair, built in 1945 and 1962 as the city's safety net, hold PFOS and PFHxS from firefighting foam the military required at the adjacent…
  • The city sued 3M, maker of the PFAS-containing firefighting foam, in federal court to recover contamination costs.
  • Caesar Creek Lake, the primary source, is a 2,830-acre Army Corps flood-control reservoir with 40 miles of shoreline draining a 237-square-mile watershed.
  • Wilmington's water was privately owned for roughly half a century: Dayton Power and Light ran the water and electric utility from 1914 until the city took the water system back around 1970.
  • The city keeps an auxiliary interconnection with the Western Water Company purely to keep outlying customers in water during main-break repairs.

  • 1945First Burtonville reservoir (100 million gallons) built, along with a water plant on Wall Street that operated until 2000.

Economic history

Reservoirs & inland lakes

Caesar Creek Lake (about 14 miles northwest of Wilmington) is a source, treated at a surface-water lime-softening plant. Two reservoirs near Burtonville, about 3 miles south of Wilmington, are kept as an alternative source and can be filled from Cowan Creek OR Caesar Creek Lake; often used when Caesar Creek Lake water is poor quality. There is also an auxiliary connection to Western Water Company for outlying customers during main-break repairs.Wilmington Water Treatment Plant · Wilmington City · +1 more

82% of these days are measurements from a gauge inside 45177 (Wilmington); the rest are estimated from the nearest gauges around it.

48,874 days of records, 1893-01-01 to 2026-10-29. Source: NOAA NCEI GHCN-Daily, 3,240 gauges in and around Ohio. A day is "gauged" when a gauge standing inside the boundary reported it, and the value is the mean of those gauges. Otherwise it is interpolated by inverse distance from every gauge reporting within 50 miles. Nothing is carried forward, back-filled or smoothed. Against NOAA nClimDiv county monthly precipitation over 136,848 complete county-months (checked 2026-10-31): correlation 0.9515, median absolute difference 0.217 in a month. Built 2026-10-31 from the Cracked Buckeye precipitation archive. Snow is the softer number — snowfall is measured by hand with a ruler, no agency publishes a gridded county snowfall series, and blowing snow defeats every observer.
