Watershed Conditions Statements

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…
April 24, 2018 –  Water levels are expected to rise again in the Rideau River watershed as a result of meltwater from the last of the snow, flow from thawing soil and rain forecast for Wednesday and Thursday.  Daytime temperatures are expected to approach 20 degrees over the rest of the week and stay above freezing at night. This will cause the remaining snow in the upper watershed to melt and, along with thawing water from the soil, begin to work its way down through the system. Rain in the order of 20 to 30 millimetres is forecast for the…
April 18, 2018 –  The snow and ice accumulation over the last several days raises the possibility of flooding in parts of the Rideau system as warmer conditions arrive on Friday. Rain and some melting has caused streamflows to increase throughout the watershed. Daytime temperatures above 10 degrees through the coming weekend and into next week can be expected to melt the remaining snow and ice. There is the potential for this meltwater to cause access issues in the low-lying communities on the Long Reach of the Rideau between Kars and Kemptville. Tributary streams such as Stevens and Cranberry Creeks…
