A bit of alarming news about the Waterhen River – according to the March 24th floodsheet, its flow is now sitting at 6,758 cfs while the outflow at Fairford is just 4,911 cfs. Lake Manitoba is going to start rising noticeably as a consequence.

PS – if you see ‘flossiest’ anywhere on one of these updates, that’s what WordPress autocorrects ‘floodsheet’ to. Or sometimes ‘bloodshot’ – it doesn’t like ‘floodsheet.’
