is impounded into a new, unnamed lake near Green Haven Correctional Facility. Shortly afterwards it crosses into the town of East Fishkill. At the town line, south of the hamlet of Stormville, it receives the Whaley Lake outlet brook. It flows westerly through more woods and swamps to where it receives the Sylvan Lake outlet brook just east of the Taconic State Parkway. After crossing underneath, it parallels the parkway south on its west side, then turns west again and makes a northward bend around another hill to once again parallel County Route 9, now Beekman Road, for a short distance, then follows the hill's base to the south. From here it meanders under the Metro-North Beacon Line south of Hopewell Junction where it receives Whortlekill Creek. It passes the Hopewell Recreation Center and then flows under NY 376. It parallels another state road, NY 82, through a wooded, undeveloped area for several miles to where it receives its longest tributary, Sprout Creek, at the Fishkill town line. It widens into a series of large pools south of Brinckerhoff, at the foot of Honness Mountain where NY 52 crosses. From here it flows more to the west-southwest, a wide stream paralleling Route 52 and the Beacon Line. It crosses under US 9 in a developed area just south of the village of Fishkill. It then turns to the southwest again and receives Clove Creek, a tributary that rises in Fahnestock State Park to the south and drains the Putnam County portion of the Fishkill watershed, just before it flows under Interstate 84. Beyond the interstate it continues southwest alongside the base of the northern slopes of Fishkill Ridge, the northernmost end of the Hudson Highlands. It detours slightly to the north near Glenham and then resumes its southwesterly course as it flows into the city of Beacon, where it passes through the eastern section of the city in a narrow valley with the Beacon Line running along its shore. There are many rapids and waterfalls as it descends more sharply to the Hudson. Here it receives its last tributary, Dry Brook, which drains Beacon Reservoir on the ridgetop. South of the Wolcott Avenue (NY 9D) bridge, the shores become wooded again as it flows over Tioronda Dam and under the remains of Tioronda Bridge. Below here the creek's estuary opens up, and after being split by a small island it
