Kelowna–Rising waters have forced the closures of the trails under Casorso Road Bridge and Gordon Drive Bridge on the south side of Mission Creek.
Water levels and flows have risen sharply from heavy rain and the continued melting of the snowpack.
Greenway users are asked to respect the barricades and signs, and use caution when crossing Casorso Road and Gordon Drive.
Motorists are asked to watch for pedestrians as they cross.
Regional Parks staff are also asking people to stay away from creek banks, which are slippery and subject to erosion.
