North Shore Channel
The North Shore Channel is a drainage canal built between 1907 and 1910 to flush the sewage-filled North Branch of the Chicago River down the Chicago Sanitary and Ship Canal. The sewage carrying duty has been largely taken over by the Chicago Deep Tunnel, but there are still occasional discharges due to heavy rains.
A sluice gate usually prevents the canal from back-draining out to Lake Michigan, although the gate must be opened occasionally to prevent downstream flooding. The channel flows southwest, and then south, through or near Wilmette, Evanston, Skokie, and Lincolnwood, and into Chicago. The south end of the channel flows into the North Branch at approximately 5100 north and 3000 west in the Chicago street address numbering system. Chicago's only waterfall within the city limits, which looks like a concrete spillway, is in River Park, where the upper North Branch drops about 4 feet (1.2 m) through a dam into the confluence. In March 2017 the Army Corps of Engineers announced a plan to remove the dam and replace it with a series of riffle pools, to allow fish to swim upstream. In July 2018 the Corps began removing the dam.
In 1999, the system of which the canal is a part was named a Civil Engineering Monument of the Millennium (as part of the Chicago wastewater system) by the American Society of Civil Engineers (ASCE).
Surrounded by parks and steep, wooded banks, the canal provides a corridor for local wildlife. Wildlife includes, but is not limited to, beaver, coyote, carp, and ducks.
Since the water quality improvement, fishing has become possible in the canal. Bass and crappie are abundant, especially at the confluence of the canal and the North Branch of the Chicago River, where the waterfall aerates the water. Canoeing and kayaking are allowed, with several put-in points along the length. In addition to water navigation, both walking and biking paths follow along nearly the entire length of the canal. The Evanston-Wilmette Community Golf Course ("Canal Shores") plays along a stretch of the canal of about 1 mile (1.6 km), and two par-3 holes play across it. In recent years the canal has also become a popular rowing venue. Home to the Chicago Rowing Foundation, Loyola High School and New Trier High School. The canal is a great place for rowing due to its high banks that act as a shelter from the wind. The northern part of the river has hosted the Wisconsin And Syracuse men’s rowing teams for a duel both in 2016 and 2019. part 
North Shore OpenEdit
The North Shore Channel has played host to the North Shore Open, an annual golf event, since 2015. The winner receives a ceremonial picture taken sitting in a tire. Dan Skowronski won the inaugural event in 2015, while Bennet Hayes won in 2016. After a one year hiatus, Dan Skowronski returned to win the 2018 North Shore Open. The North Shore Channel plays a role on most of Canal Shores' 18-hole layout.
