24 Water approaches Urbana Pike near Monocacy National Battlefield.
21 Maryland Route 26 is flooded near the Monocacy River bridge.
20 Water reaches Gambrill Mill on the Monocacy National Battlefield.
17 Significant lowland flooding is occurring along the river, with backwater flooding also occurring. Numerous roads are closed. Water is approaching the parking lot at Gambrill Mill on the Monocacy National Battlefield. Backwater flooding from Carroll Creek is likely approaching the underside of the bridge leading to the Frederick city wastewater treatment plant.
16 Much of Pinecliff Park and Rivermist Park in Frederick are flooded. Buckeystown Community Park is also flooded with water approaching the parking lot. Waters are also approaching the Frederick city wastewater treatment plant and the Ballenger Creek wastewater treatment plant. Significant backwater flooding is occurring. Several roads will be closed along the river and adjoining creeks.
15 Both banks of the river are flooded. Water begins to flood low-lying fields at Monocacy National Battlefield. Water reaches the access road of the Frederick city wastewater treatment plant. Backwater flooding is occurring on several area creeks, particularly Carroll Creek in Frederick.
14 Two low-water crossings, one on Michaels Mill Road /State Route 880/ in Buckeystown, and one on Retreat Road north of Frederick, begin to flood.
13 Water covers portions of Pinecliff Park in southeast Frederick. Water also approaches Rivermist Park in northeast Frederick.
