Vancouver, British Columbia, Canada is home to several bodies of water within and around its boundaries. Of over 30 historically salmon-bearing streams diverted into underground culverts due to urbanization, several have been restored to a state visible and habitable again by plants and wildlife. Spanish Bank Creek Spanish Bank Creek flows north through Pacific Spirit Regional Park near U.B.C. It terminates at the beach under the Spanish Bank cliffs on Northwest Marine Drive. Urban development rendered the creek impassable to adult fish for many decades but the creek has been restored and, since 2001, sockeye salmon have been returning there to spawn. Musqueam Creek Musqueam Creek, and its tributary Cutthroat Creek, begin in Pacific Spirit Regional Park and flow south through the Musqueam Reserve in the Southlands neighbourhood of Vancouver, where they meet before entering the Fraser River estuary. The creeks are protected by the federal Department of Fisheries and Oceans. Musqueam Creek is in the process of restoration by the Musqueam Band, and Coho salmon and Chum salmon have returned to this creek in small amounts. Still Creek Still Creek is a 17 km long creek that begins in Vancouver, crosses into Burnaby, and terminates in Burnaby Lake. In Vancouver, the Still Creek watershed is bounded by 1st Avenue, 49th Avenue, Nanaimo Street, and Boundary Road. Portions of the creek are visible and the City of Vancouver is working to uncover (or "daylight") more of the creek; however, most of the Vancouver section still lies underground, directed by culverts and storm sewers. Beaver Creek Beaver Creek begins at Beaver Lake and terminates in the ocean, under a bridge at the intersection of Pipeline Road and Stanley Park Drive. Beaver Lake Beaver Lake is a lake in the interior of Stanley Park, surrounded by walking trails and home to many aquatic birds. This lake is being reclaimed by the forest because of the water lilies that have been added. The lily pads reduce the amount of oxygen in the water, which has slowed the lake's ability to decompose organic material. Due to this, the lake is slowly becoming a swamp. Lost Lagoon Lost Lagoon is an artificial, captive 17-hectare body of water, west of Georgia Street, near the entrance to Stanley Park. It was created in 1916 by the construction of the Stanley Park causeway. It is a nesting ground of many species of bird, including swan, Canada geese, and
