Forecast for 2024-04-16

River conditions forecasts posted on 2024-04-16 by Ottawa River Regulating Committee

Spring runoff from the April 11-13 rainfall event and the melt of the remaining snow in the northern part of the watershed continue to flow in the Ottawa River. Levels and flows have started to decline in Mattawa, peaked at Pembroke, and are slowly coming to a peak at Lake Coulonge. Elsewhere, levels are expected to continue increasing prior to stabilizing later this week. Precipitation forecasted (10 – 25 mm) from Wednesday to Friday is expected to bring additional spring runoff into the river system, which will keep water levels stable or slowly decreasing over the coming week, in all locations. Please refer to the forecast section of our website for more information about the water levels in your area. Reservoirs in the northern part of the watershed are being used to store spring runoff and reduce flows and levels in downstream river reaches. Minor flooding in low-lying areas may occur over the next week as a result of the increased spring runoff. Low-lying areas are those locations that regularly flood during the spring freshet period.   See our press release for more information.
