Easing temperatures and dwindling snow packs in areas has seen stabilization of many rivers through the region. River levels remain high in rivers fed by lake systems, including the Nautley River system.


In the Bulkley Valley flows have been slowly climbing, and flows at the Bulkley River at Smithers gauge (08EE005) is at 5.3m and 940 m3/s. Rises up 1050 m3/s (5.5m) are possible into Monday. Similar modest rises are possible in tributaries along the Bulkley Valley (including the Telkwa River).


Other areas are expected to see generally stable or improving flows over the next few days. Hot temperatures are forecast to return into next week, and additional river rises are expected in the middle or later part of next week.
The River Forecast Centre will continue to monitor conditions and update this advisory as conditions warrant.
