One hour of rain on the afternoon of the 30th pushed floodwaters dangerously close to entering homes in low-lying parts of Cobden when stormwater drains could not cope. Flood waters in Eel Street carried rubbish, debris, oil and diesel on to properties.
Range Creek overflowed.
Water in lower Bright and Peel Streets got so close to properties that the Grey District Council moved to close the roads. The water subsided in just under an hour.
Intense surface flooding was reported around McKendry's corner at Omoto.
