Watching the Rut Happen: 132 Weekly Reports from Ohio

Ohio requires every deer to be checked in the season it is taken, and the state publishes the running county tallies on a weekly schedule from early October through early February. Do that for seven seasons across eighty-eight counties and you get something no other Midwest state can produce: a real-time picture of when deer actually die. Plotted week by week, the statewide kill is not a smooth arc. It is a two-engine machine, a November rut ramp carried by bowhunters and a firearms spike in early December that dwarfs everything around it.

Almost every state reports deer harvest the same way: once, after the season closes, as a single annual number per county or per unit. Ohio is different. Because the state mandates that hunters check each animal (by phone, online, or app) the wildlife agency can publish a running season-to-date tally on a weekly schedule while the season is still happening. FDR ingested those weekly bulletins for seven seasons (2019–20 through 2025–26): 88 counties, roughly 18–20 reports per season, 11,616 county-week records in total. The published numbers are cumulative, so the harvest in a given week is the difference between consecutive reports: a derivation that has to respect the report calendar (a gap that skips a bulletin is not one week) and tolerate the small downward corrections the agency issues as late checks reconcile. Done carefully, the result is a kill curve with a heartbeat.

For the first six or seven weeks of the season the only deer being checked are archery deer, so the October-and-November curve is a clean read on bowhunter effort. And bowhunter effort tracks the rut. From a sleepy opening (Ohio's first four weeks of October added only about 27,000 deer in 2024, roughly a tenth of the season), the weekly kill climbs steadily as chasing and cruising bring mature bucks into daylight, peaking in mid-November near 19,000–21,000 deer in a single week before the firearms season arrives. That mid-November high is the closest thing the harvest record has to a fingerprint of peak rut activity, and it lands in the same window every year. What follows it is just as telling: a brief post-rut lull in the week before Thanksgiving (2024's pre-gun week fell to 5,517) as the chasing winds down and hunters wait for the opener.

Every other state hands you one number in February. Ohio hands you the season as it happens. The shape of it is the rut.

Then the guns open, and the curve detonates. Ohio's week-long firearms season opens the Monday after Thanksgiving, and the single biggest weekly harvest of every season lands on it: 46,367 deer in one report in 2024, 49,015 in 2025. Because the opener straddles the calendar differently each year, the spike shows up in week 10 or week 11 depending on where Thanksgiving falls, but the magnitude is consistent: the two firearms weeks in early December carried 38.8% of the entire 2024 harvest (92,388 deer) and 38.7% of 2025's. Nothing in the archery season comes close. After it, the curve settles into two recurring aftershocks that appear in the same weeks every year: a bonus firearms weekend in mid-to-late December (17,000–19,000 deer) and a muzzleloader pulse in the first week of January (13,000–14,000). A hunter who knows those pulses exist knows exactly when the woods will be crowded and when they will empty.

A single end-of-season total answers how many. It cannot answer when, and for a hunter, when is most of the question. The weekly series turns the harvest from a scoreboard into a calendar: it dates the rut ramp, dates the firearms crush, dates the quiet weeks in between, and does it consistently enough across seven seasons that the pattern is plannable rather than anecdotal. It also makes the data self-auditing. Because each week's figure is the difference of two published cumulative tallies, any number in this paper can be traced to the exact bulletin it came from, including the agency's own small downward corrections, which we carry as printed rather than smoothing away. That combination (in-season timing plus a fully reconstructable audit trail) is what a mandatory-check state can offer and a survey state structurally cannot.

The shape is stable enough to plan against. Expect a slow, building October; a rut-driven archery peak in the second and third weeks of November; a short lull the week before Thanksgiving; and then the firearms opener, which will out-produce any archery week by a factor of two. Expect the woods to reload for a mid-December weekend and again for early-January muzzleloader, and expect the tail to run into February at a trickle. None of that is a forecast in the predictive sense. It is simply what seven seasons of the only in-season deer dataset in the Midwest have done, every year, in the same weeks. The rut is not a rumor in Ohio. It is a line on a chart, and the chart is public.
