Confluence and bypass channel
Confluence and bypass channel

Yet another major project milestone will be passed this week when the Clark Fork River is diverted into the bypass channel. According to the EPA, on Tuesday March 18 the berm at the outlet will be breached, allowing water from the Blackfoot to backfill the bypass channnel. Next week, the inlet will be opened, fully diverting the Clark Fork River around contaminated sediments and into the channel. The bypass channel is a key measure to reduce downstream impacts. For details, see the EPA press release,
the EPA’s weekly update (PDF) or coverage in the Missoulian.
