Thunder Creek (Saskatchewan)

Thunder Creek begins at the man-made reservoir and flows into the Thunder Creek meltwater channel. Once in the valley, the river meanders its way along the valley floor. Along the way, it is joined by several creeks flowing in from the coulees. The western tributaries of upper Thunder Creek watershed drain a hilly plateau called the Vermilion Hills. There are four small lakes in a chain along the course that are part of two Important Bird Areas, including Paysen (Horfield) Lake, Williams Lake, Kettlehut Lake, and Pelican Lake. As the water level of Pelican Lake — the last lake in the chain of lakes — isn't always high enough to provide an outflow, Sandy Creek, which is about one kilometre downstream from Pelican Lake, becomes the primary water source for the last leg of Thunder Creek. Communities found along the river's course include Moose Jaw, Boharm, and Caron. Highways 1, 19, 627, and 643 cross Thunder Creek. Darmody Dam South-east of Darmody, in a coulee upstream from Pelican Lake, Darmody Dam () was built on a tributary in 1929. The dam is high and the reservoir has a capacity of . It is owned and operated by the Saskatchewan Water Security Agency. Tributaries Thunder Creek tributaries include: • Allin Creek • Aquadell Creek • Sandy Creek • Wilson Creek == Important Bird Areas ==

There are two Important Bird Areas (IBA) of Canada along the course of Thunder Creek. In 1990, the Riverhurst Management Plan, which was developed by Ducks Unlimited through the North American Waterfowl Management Plan, was initiated to stabilise water levels in the lakes and marshes by pumping in water from Lake Diefenbaker. Stable water levels provide habitat for birds and other wildlife. Paysen /Kettlehut Lake Paysen/Kettlehut Lake IBA SK 057 encompasses Paysen, Williams, and Kettlehut Lakes and the surrounding river valley. The IBA site totals with an elevation range of to . It is Crown land that is composed of grasslands, ponds, marshes, and creeks. Birds found in the lakes and protected area include the western grebe, black-necked grebe, Franklin's gull, Forster's tern, marsh wren, sedge wren, common yellowthroat, LeConte's sparrow, and Nelson's sparrow. Pelican Lake Pelican Lake IBA SK 059 is about downstream and south-east of SK 057 Paysen/Kettlehut Lake IBA and encompasses all of Pelican Lake and much of the surrounding landscape. Pelican Lake is the largest of the four lakes along the course of Thunder Creek and is recognised as a regional Western Hemisphere Shorebird Reserve Network (WHSRN) site. The IBA covers an area of with an elevation range of to . Ducks Unlimited built three cross-dykes on Pelican Lake in 1964, 1973, and 1989 to help maintain water levels. Some of the birds commonly found at the IBA include the American avocet, marbled godwit, Wilson's phalarope, grey plover, tundra swan, mallard duck, gadwall duck, western grebe, blue-winged teal, northern pintail, and the American white pelican. == Besant Recreation Site ==

Besant Recreation Site () is a 300-acre provincial recreation site along the course of Sandy Creek in the RM of Caron No. 162. Access to the park is off the Trans-Canada Highway, east of Mortlach. Besant Recreation Site is well treed and has about 100 campsites, sandhills, a spring-fed pond, a swimming area, and access to Sandy Creek. The pond is stocked with fish. The park was home to the Sandy Creek Gospel Jamboree. == Fish species ==

The most commonly found fish in the Thunder Creek river system is the northern pike. Other species include the common carp, burbot, largemouth bass, yellow perch, and walleye. == See also ==
