How Montgomery County began

Montgomery County was created by an act of the Ohio General Assembly passed at Chillicothe on March 24, 1803, dividing Hamilton and Ross counties, and took effect May 1, 1803, with its first court held that July at Col. George Newcom's tavern in Dayton; it takes its name from General Richard Montgomery, a Continental Army officer killed in the 1775 assault on Quebec. Dayton, already settled in 1796 at the forks of the Great Miami and Mad rivers, was named county seat from the start and has remained the seat ever since. The land had been Shawnee and Miami hunting and village ground until the Treaty of Greenville ceded it in 1795, and the county's Adena and Fort Ancient sites -- the Miamisburg Mound, one of the largest conical burial mounds in the eastern United States, and SunWatch Indian Village, an excavated and reconstructed Fort Ancient town on the Great Miami -- are national landmarks. Montgomery County's history since organization has been shaped repeatedly by the Great Miami River: by canal and National Road traffic in the early 1800s, by the catastrophic flood of March 1913 that killed hundreds across the valley and led to the county-spanning Miami Conservancy District dam system, and by the industry -- canal milling, then National Cash Register and Wright-brothers-era aviation manufacturing -- that grew up along its banks.

Dayton was already the largest settlement in the area when the county was organized in 1803 and was named county seat from the start; the first court session was held that July at Col. George Newcom's log tavern, which also served as the settlement's first store, church and school. A brick courthouse replaced the tavern around 1806, gaining a cupola in 1815 and a bell in the winter of 1816. The Greek Revival courthouse that still stands at Third and Main streets, modeled by architect Howard Daniels on the Temple of Hephaestus (then called the Temple of Theseus) in Athens after Dayton citizen Horace Pease showed county commissioners sketches of the Acropolis, was built beginning in 1847. It has been described as the nation's best surviving Greek Revival courthouse and was listed on the National Register of Historic Places January 26, 1970.

Almost every day here is a measurement: 100% of them come from a rain gauge standing inside Montgomery County itself.

48,224 days of records, 1893-06-02 to 2026-10-28. 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.
