Hydrology
The primary inflow is the Rideau Canal arriving, at the northwest, from Indian Lake over the control structures and lock at Chaffey's Lock, which gives its name to the tourist and cottage community located there. Secondary inflows are: Loughborough Lake Creek, at the east, which flows into Hart Lake and then into Opinicon Lake; and Rock Lake Creek, at the southeast, arriving from Lower Rock Lake. The primary outflow, at the northeast, is over the control structures and lock at Davis Lock to Sand Lake. The canal eventually flows via the Cataraqui River to Lake Ontario.
Recreation
This lake is a popular fishing spot and location for cottagers. The Opinicon Hotel, a historical resort, is located at Chaffey's Locks.
Natural history
The Queen's University Biological Station, built in 1945, is on the lake. In May 2010, Sugarbush Island was designated a conservation area.
