About Mohican River at Loudonville
Loudonville calls itself the Canoe Capital of Ohio and the weekend volume on this water backs the claim up. The gauge is on the Black Fork just above the confluence that forms the Mohican proper, which is the standard reference for the liveries running the Loudonville stretch.
One caveat worth knowing about this page: USGS published daily statistics for this station only through the early 1990s, so the seasonal median and the record figures above come from a short historic window rather than a long modern one. The live reading is current; the comparison is against a smaller sample than most gauges on this site.
Mohican River at Loudonville — common questions
5 questions
Is this gauge on the Mohican itself?
It is on the Black Fork immediately above the Mohican, which is the water the Loudonville liveries actually run and the station everyone in town uses. Below the confluence the Clear Fork adds to it, so expect a little more water on the lower stretch than this figure alone implies.
How reliable is the seasonal comparison on this page?
Less than on most gauges here, and the reason is worth saying plainly. USGS statistics for this station cover a short run of years ending decades ago, so the median is drawn from a small sample. The live reading and its trend are solid; treat the percent-of-normal as a rough guide rather than a long-record figure.
How fast can Mohican River at Loudonville come up?
Fast. It is free-flowing, so rain upstream moves it directly. Several feet in a few hours is normal after a heavy storm.
Is Mohican River at Loudonville high or low for this time of year?
The USGS median flow for mid-September here is 104 CFS, from 7 years of record (1985–1991). Today is 70% of it. The comparison is what makes the raw number mean anything: the same reading is a drought on one river and a flood on another.
How often does this reading update?
USGS transmits from gauge 03131500 every 15 to 60 minutes, and the National Weather Service reissues the flood forecast for LDVO1 a few times a day — more often when the river is rising. This page refreshes from both when you open it. The timestamp is in the gauge's local time.
