Eagle Creek (Saskatchewan)
Eagle Creek is a river in the Canadian province of Saskatchewan. The watershed of Eagle Creek is within the semi-arid Palliser's Triangle and is the major drainage system in mid-western Saskatchewan between the South and North Saskatchewan Rivers. Eagle Creek begins at the eastern end of Eaglehill Lake and travels through a glacier-cut valley in the moist, mixed grasslands ecozone of Canada en route to the North Saskatchewan River. The North Saskatchewan River merges with the South Saskatchewan River farther downstream to become the Saskatchewan River. There are three communities, one regional park, and several highways along the river's course. The communities include Stranraer, Herschel, and Anglia. Highways 51, 31, 4, and 14 are significant highways that cross the river. Description For much of Eagle Creek's course, it follows a meltwater channel that was formed near the end of the last ice age. Both this channel and the North Saskatchewan River meltwater channel to the north were important in draining the land to the west – present-day Alberta. As the glaciers were receding, several large proglacial lakes were formed near Eagle Creek, including Glacial Lake Red Willow to the north-west, Glacial Lake Unity directly north, and to the east, Glacial Lake Saskatchewan. These lakes and meltwater channels also left large volumes of glaciolacustrine deposits behind. By about 10,000 BC, the course of Eagle Creek had become ice-free and by about 7000 BC, the drainage basin and Geomorphology began to resemble that of present-day. At the southern most point of Eagle Creek is the Stranraer Terrace. The northern slopes of the Stranraer Terrace, which rises above the surrounding terrain, flow into the river. The terrace is considered to be the northern extreme limit of the Missouri Coteau. Course Eagle Creek begins at the eastern end of a small (), narrow lake called Eaglehill Lake in the RM of Tramping Lake No. 380. The river's course from beginning to end has a "U" shape to it. From Eagle Hill Lake, the river flows into the valley formed from glacial meltwaters and meanders southward where it widens to form Tramping Lake. Tramping Lake, at , is a long, shallow, and narrow lake that snakes along the valley floor. From the southern end of Tramping Lake, Eagle Creek carries on southward and flows into the 1383-hectare, man-made Opuntia Lake. From the Opuntia Lake, the river heads south-east towards the Stranraer Terrace and the communities of Stranraer, Herschel, and Rosetown. At Herschel, there's the Ancient Echoes Interpretive Centre and a buffalo jump at Coal Mine Creek coulee. After Rosetown, Eagle Creek heads east and flows out of the valley and into the flatter prairie. From there, the river re-enters a valley and begins its northward journey towards the North Saskatchewan River. Along the river's course, in the RM of Harris No. 316, is Eagle Creek Cement Bridge. It was built in 1925 and is on the Canadian Register of Historic Places. The bridge is a reinforced concrete, double-span bowstring bridge, one of nearly 90 such
