Watershed Conditions Statements

May 10, 2018 – The Mississippi Valley and Rideau Valley Conservation Authorities are advising residents that water levels appear to be stabilizing. Some nuisance flooding (Petrie Island, Boise Wood) has occurred. Rain that fell this morning was not enough to have an impact and there is no rain forecast for the next five days that would cause levels to increase again. Water levels will gradually decline to normal summer levels over the next two weeks barring the development of a significant weather system.. Note that streambanks are slippery along the Ottawa River, water is fast moving and still very cold.…
May 10, 2018 –  The Flood Warning issued on April 30 for Bobs and Christie Lakes remains in effect. Levels on both lakes continue to decline at the rate of about one centimetre per day. However, levels are still above the ‘Full Supply’ threshold at which damage can occur. Rain today is not expected to be sufficient to affect the decline of the lake levels and no rain is forecast for the next five days. Levels can be expected to recede to summer levels over the next week barring a significant weather system forming and moving through the region. Caution…
May 7, 2018 –  The Flood Warning issued on April 30 for Bobs and Christie Lakes remains in effect. Levels on both lakes have declined slightly but both remain above the ‘Full Supply’ threshold at which damage can occur. This decline will continue for the next two days with no precipitation forecast. However, rain is forecast for Thursday and through next weekend with a possible five day total close to 55 millimetres. If this amount falls, water levels are likely to increase but the primary impact is expected to be on Bobs and Christie Lakes. Outflows from Bobs Lake are…
May 4, 2018 –  This message is an update to the RVCA flood warning of April 30. A weather forecast from the Ministry of Natural Resources and Forestry has the possibility of generalized rain up to 25 millimetres (mm). An additional 25 mm could fall in localized storm cells.  If the rain occurs as forecast, water levels can be expected to rise again throughout the watershed. However, no flooding is expected in the lower reaches of the system downstream of Smiths Falls. Water levels have continued to increase gradually on Bobs and Christie Lakes with some minor flooding of low-lying…
April 30, 2018 – This message is to update the status of flood conditions in the Rideau River watershed. No flooding is expected in the lower reaches of the system downstream of Smiths Falls although water levels can be expected to increase with rain forecast over the latter half of this week. Bobs and Christie Lakes continue to be at risk for flooding. Higher levels on Christie Lake in particular can be expected as necessary releases are made to control levels on Bobs. No rain today or Tuesday will help but, if rain forecast for Wednesday and beyond is received,…
April 28, 2018 – This message is specific to Bobs and Christie Lakes but may apply to other lakes in the area where remotely accessible monitoring equipment is not installed. Property owners are advised to go to their cottage properties and assess conditions for themselves. Rain overnight has caused levels on Bobs and Christie Lakes to increase to flood levels. Additional rain forecast for today (Saturday) and Sunday will cause further increases. Some relief is expected on Monday and Tuesday. More rain is forecast for later in the week that will slow the decline on both lakes. Levels of Bobs…
