On the Shuswap River, flows are slowly declining but remain high. Flows on the South Thompson River are still rising, however the rate of rise declined over the weekend; peak levels on the South Thompson River and Shuwsap Lake are expected to occur through this week, unless significant rainfall occurs in the next few weeks.
The River Forecast Centre will continue to monitor conditions and update this advisory as conditions warrant.
