Moodna Creek is a small tributary of the Hudson River that drains eastern Orange County, New York. At 15.5 miles (25 km) in length from its source at the confluence of Cromline Creek and Otter Kill west of Washingtonville, it is the longest stream located entirely within the county.Despite its small size relative to the Hudson, it has been a major influence on the topography of eastern central Orange County.
The 75 acres (30 ha) of tidal marsh in the creek's estuary, between Route 9W and the Hudson, are home to several rare plants and natural communities. Anadromous fish species, such as striped bass, spawn there as well.This fish supply has been attractive not only to human anglers but to predatory bird species as well: bald eagles and ospreys have been seen feeding in the Moodna's marshes Bald Eagles have been confirmed nesting on the Black Meadow Creek.
The six miles (10 km) between Woodbury Creek and Old Forge Hill Road in Cornwall have become a popular place for whitewater kayaking.Section ratings on the International Scale of River Difficulty range from Class II to Class IV.Anglers, too, have taken advantage of the stream above the salt marshes. The New York State Department of Environmental Conservation keeps Moodna Creek regularly stocked with brown and rainbow trout.
