Moodna Creek and its watershed and major tributaries Moodna Creek and its watershed and major tributaries

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. Its 187.2-square-mile (485 km²) watershed, including not only both its parent streams but Woodbury Creek as well, reaches as far inland as Warwick as well as 21 other area communities. Near Salisbury Mills it is crossed by the Moodna Viaduct, the longest actively used railroad trestle east of the Mississippi.

Name

"Moodna" is a corruption of the Dutch "Moordenaars", from Murderers' Creek, its original name. Local lore has it that the name came from the massacre of the Stacys, an early family of settlers, along its banks. Murderers' Creek was in common use in the mid-18th century, however by the dawn of the 20th Moodna was being used on maps although the older name persisted.

Course

From the confluence, just off NY 208, the Moodna flows through woods and field alongside the highway for a short distance, then veers southwestward to where it crosses NY 94. The creek and Route 94 will keep close company for several miles as it turns eastward again into Washingtonville, where it crosses under 208 just south of downtown. Past the village, Route 94 and the creek enter first the Town of Blooming Grove and then Cornwall. They run close together at first, then further apart as the Moodna valley opens up just to the north of Schunemunk Mountain. At Salisbury Mills the viaduct crosses 193 feet (59 m) overhead.

After that point, the Moodna turns southward slightly, following the curve of Schunemunk's north end under the Thruway and leaving the Route 94 corridor. It descends into the narrower valley, forming the eastern boundary of Storm King Art Center. Here the already wide creek gets even wider with the addition of Woodbury Creek just after it tumbles over a small dam. Immediately afterwards NY 32 crosses between Vails Gate and Mountainville. The wide, rocky stream curves between steep, wooded hills to enter New Windsor and cross Old Forge Hill Road just below Knox's Headquarters State Historic Site, receiving its only major northern tributary, Silver Stream, in the process. Following Old Forge Hill briefly, it passes its last road crossing at US 9W, site of a small hamlet referred to once as Moodna Village and location of a small cottage once occupied by James and Ellen Gaffney, then bends southwards back into Cornwall to empty into the Hudson amid tidal marshes. The CSX Hudson River Subdivision freight line crosses right at its mouth.

Natural history

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.

Two herpetofaunal species listed by the NYS Department of Environmental Conservation occur along the Moodna. One, the Northern Cricket Frog (Acris c. crepitans) occurs along the length of the Black Meadow creek, which runs from Warwick, NY into Chester, NY. The Northern Cricket Frog, NY's only endangered frog species, occurs in its most numerous population along the Black Meadow creek, in the Orange-County-owned Glenmere Lake reservoir lands.

While the water quality in that area remains generally good, there is effluent from the Town of New Windsor's sewage treatment plant. In November 2003 the Riverkeeper environmental organization sued the town over discharge into the creek leaking from two manholes into the creek. It was settled in 2005 when the town agreed to repair the manholes, remediate the area and provide public access to the water.

Recreation

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.

History

During colonial times, and for a short time after independence, the creek formed part of the boundary between Orange and Ulster counties. In 1798, however, Rockland County was created, and the line was adjusted northward, giving Orange the current towns of Newburgh, Montgomery and Crawford as compensation for the lost territory.

Heavy rains during the April 2007 Nor'easter caused the creek to flood extensively in its upper course in and around Washingtonville. Route 94 was blocked in both directions, and Route 208 from the south, leaving only northern access to the village available. Almost a hundred residents had to leave their homes for temporary shelter at a local elementary school.

Hurricane Irene caused the creek to swell, coming nearly to the platform of the 9W bridge, and washing out an area at the Forge Hill Road bridge. This caused the closing of part of Butternut Drive, and all of Forge Hill Rd, except the easternmost 640 feet, from Route 9W to Staples Lane. The portion east of Staples Lane remains open to local traffic, until the east end of the bridge, which is unstable. One house on Butternut Lane has been condemned, and the property fenced off, due to the dangerous dropoff on the property.
