Sprout Creek begins in Millbrook, at in elevation. Paralleling Oak Summit Road, the creek flows generally southward towards New York State Route 82, where it passes through Verbank. The creek turns towards the west, though after reaching Verbank Village, it resumes its southwestern course. It turns around several small hills and mountains, and later intersects New York State Route 55. Shortly thereafter, Sprout Creek crosses the Taconic State Parkway; it soon receives Jackson Creek. The Jackson Creek watershed covers of land, draining a large portion of Union Vale into Sprout Creek, and has a small annual stocking of around 700 brown trout. Sprout Creek continues generally towards the southwest, and later towards the south, before once again passing under Route 82. The bridge over the creek, located in the town of Fishkill, was built in 1934. At long, the bridge carried an AADT of 19,400 vehicles as of February 2006. In 1772, Albanian engineer William Verplanck constructed a dam across the creek. He also built a grinding mill on the creek's banks; during the American Revolution, this mill ground a large quantity of grain for the soldiers stationed at Fishkill. The creek ends at the Fishkill Creek, just north of New York State Route 52. Sprout Creek also passes through Sprout Creek Farm, an educational farm, in the town of LaGrange within the city of Poughkeepsie.
Watershed
Comprising 24% of the overall Fishkill Creek watershed, the Sprout Creek subwatershed encompasses about of land—of which 17% was being used for agricultural purposes in 2000. The creek's quality is described as "good" by the Fishkill Creek Watershed Committee, though agricultural operations, sewer treatment plants, and septic systems led to pollution at certain times during a study from 1973 to 2002. It drains portions of La Grange, Union Vale, Wappinger, and East Fishkill. One of only three trout creeks in Dutchess County, the creek is annually stocked with 6,000 brown trout; wild trout are also present. A group of local residents formed the Sprout Creek Association, after the operation of a nearby rock mine prompted concerns about the creek's environmental health.
