Damage occurred to the Minell Pipeline, just west of McAuley, causing the shut-off.
The damage is reportedly due to an excavator coming into contact with a natural gas pipeline on the site.
Russell, Inglis, Roblin, Riding Mountain West, Grandview, Gilbert Plains and Dauphin are served by gas from the Minell Pipeline.
Manitoba Hydro reports no injuries and that this incident poses no threat to nearby communities.
Natural gas is venting safely, and local staff are on the scene with emergency personnel to ensure the site remains safe.
Specialized gas crews will begin repair work tomorrow morning.
Because of the warm weather we are experiencing and low natural gas usage, it's anticipated that residential customers will not experience a disruption to their service.
Manitoba Hydro has sent a compressed natural gas trailer to Dauphin from Winnipeg to help supplement gas service.
An early estimate indicates the damage will take two to three days to repair.
Manitoba Hydro said in a press release that they would update the situation further once staff performed a more thorough examination.
