Affected Communities: 
District of Lillooet, Electoral Area A, Electoral Area B

BC Hydro has advised of increased water flows in the Lower Bridge River this spring.

This change in flows will help to reduce the risk of high flows in August, during the Gates Creek run on Seton River, and will also help to reduce the risk of spill events this fall on the Lower Bridge River.

  • The first increase is planned for Wednesday, May 5, 2021 with an increase in water released from Terzhagi (TRZ) Dam.

Dam Date Discharge Change Stage Change*
TRZ May 5, 2021 ~11.1 m3/s to ~25.0 m3/s ~ (+) 0.33 m

*Estimated stage change at Water Use Plan flow compliance point. Actual discharge amount may vary.

Members of the public are reminded to use extreme caution when active in and around the river as water levels may rise suddenly and without warning.

Residents and visitors are reminded to stay away from the edges of the river during this high flow period and continue to be mindful of water safety throughout the year.
