| Measure | Flow | Time | Relative to latest reading |
|---|---|---|---|
| Highest reading | 32 cfs | Oct 16, 10:00 PM EDT | within the last hour |
| Lowest reading | 16 cfs | Oct 15, 4:45 PM EDT | 29 h earlier |
Source: computed from USGS continuous readings (Water Data API) to Oct 16, 10:00 PM EDT. Each row compares the latest reading with the reading closest to that many hours earlier; the arrow is steady (▬) when the change is within 1%.
