Yanco Weir Boat Ramp sits on the Murrumbidgee River near the historic Yanco Weir structure, which was originally built in 1928–29 to divert flows from the Murrumbidgee into the Yanko, Colombo, and Billabong Creeks system for irrigation.

The weir is listed on the New South Wales State Heritage Register and is considered one of the earliest weirs constructed on the Murrumbidgee to regulate water supply to the Murrumbidgee Irrigation Area.

The boat ramp is noted as an access point along the Murrumbidgee waterway.

The weir itself functions as a significant flow-control structure, though it acts as a barrier to native fish passage during lower flow conditions, with fish passage estimated to be possible less than 4% of the time.
