The Rutherford Creek is a 25 km left tributary of the Green River in the Canadian province of British Columbia .

River course

Rutherford Creek has its headwaters in the Pemberton Icefield at an altitude of about 1500  m , just under 30 km north of Whistler in the Pacific Ranges , a part of the Coast Mountains . The Rutherford Creek initially flows 10 km in a south-southeast direction and then turns east. The eastern part of the Appa Glacier and the southern part of the Ipsoot Glacier are drained via the Rutherford Creek. This flows into the Green River 3.5 km above the Nairn Falls . The British Columbia Highway 99 (Whistler-Pemberton) and the railway line of the Canadian National Railway to cross the river less than a kilometer above its mouth.

Hydrology

Rutherford Creek drains an area of ​​179 km². The mean discharge is 11.6 m³ / s. The highest monthly outflows usually occur during glacier ice melt in June and July.

Use of hydropower

There is a weir 10 km above the mouth, at which part of the river water is fed to the run-of-river power plant at the mouth of the river via an 8 km long underground pressure pipe . The power plant went into operation in June 2004. It has 2 Pelton turbines with a total output of 49.9 MW. The planned annual electricity generation is 180 GWh. The fall height is 378.5 m. The expansion flow is 17.2 m³ / s.

Kayak facility

As a replacement measure for the construction of the hydropower plant, the Rutherford Whitewater Kayaking Facility was created below it . This includes a 600 m long artificial kayak stretch with a gradient of 17 m and a flow rate of 17.5 m³ / s.
