The [[Grand River (Ontario)|Grand River]] flows southward along the city's east side. Its most significant tributary within the city is Laurel Creek, whose [[Sunfish Lake (Ontario)|source]] lies just to the west of the city limits and its mouth just to the east, and crosses much of the city's central areas, including the University of Waterloo lands and Waterloo Park; it flows under the uptown area in a culvert. In the city's west end, the [[Waterloo Moraine]] provides over 300,000 people in the region with drinking water. Much of the gently hilly Waterloo Moraine underlies existing developed areas. Ongoing urban growth, mostly low-density residential suburbs (in accordance with requests by land developers), will cover increasing amounts of the remaining undeveloped portions of the Waterloo Moraine.
