Illecillewaet flowing through the blockage

Illecillewaet River and Lanark Blockage

This afternoon the blockage and the river downstream of the blockage were flown over by a helicopter carrying a team of assessors.

The river is flowing through the blockage and there appears to be no increase in ponding.

Inflow equals outflow and the water gauge at Greely (downstream) is showing normal seasonal flow.

There does not appear to be a threat at this time. However, monitoring will continue:

CPR operations will report any unusual flow at their crossings, and

Steps are being taken to monitor daily from the highway

A further update will be released by the City of Revelstoke if the status changes.

Any changes on the Lanark Slide will be posted online at
