Lower Trent levels will decrease as well. The temperature variations around the freezing mark makes ice weak along the shoreline which is then easily broken and moved by windy conditions. Rice Lake is being maintained slightly above average and the Lower Trent is being sustained currently by the minimum flows out of the Otonabee River. Water levels are expected to increase from lower Youngs Point down to Rice Lake. The Gull River reservoirs are 79% full. watershed is a subset of the larger drainage area included in one of the models. Flows and levels will remain high through Minden. approach of explaining instream loads based on watershed attributes has limitations for stream reaches for which the actual hydrologic Subsequently the Gull and Burnt River Reservoir Lakes are full or overfull and levels will continue to increase. The active drawdown will continue and the rate of drop will be largely dependent on the rainfall received. The temperature variations around and above the freezing mark makes ice weak along the shoreline which is then easily broken and moved by windy conditions. Flows on the Otonabee River are below average for this time of year and declining. The Otonabee River is navigable however flow is high and will remain high. SPARROW models are statistical in nature and their uncertainty is often a function of both the quality and number of data available for calibration. Manteufel, S.B., and Robertson, D.M., 2017, Water-quality and lake-stage data for Wisconsin lakes, water year 2014: U.S. Geological Survey Open-File Report 2016–1131, 170 p., https://doi.org/10.3133/ofr20161131. Water levels on the Kawartha Lakes are well below average, but are levelling off due to the recent rain and ongoing snow melt. The drawdown continues, and the rate of drop will be largely dependent on the rainfall received. Most lakes are near long term average water levels. Extensive rehabilitation efforts were implemented to improve water quality. Lake levels are monitored daily and assessed in relation to estimated runoff amounts, however they are susceptible to changes in response to the future precipitation amounts. One of the challenges for SPARROW, as well as for any watershed SPARROW models provide predictions of “total”, “incremental”, and “delivered” yields, based on corresponding measures of load. Due to the significant total amounts of rain and localized snowmelt, water levels and outflows continue to increase. of the reach outlet. Black River flows are above average and continue to increase. Any watershed condition updates will be released by your Conservation Authority. Plenty of lakes with quality … The current two week forecast is calling for approximately 10 to 20 mm of rainfall. After a wetter than normal April (100-125 mm of rain fell versus the monthly average of 76 mm) the Haliburton area received a significant amount of rainfall (100-125mm) during the first week of May. |Back to Top| Black River flows and Severn River flows are below average. Lower Buckhorn Lake and Scugog Lake levels are above average for this time of the year and increasing. Lake stage and tributary inflows are monitored to assist in developing water and nutrient budgets. Incremental drainage areas are represented here as "catchments". SPARROW models are atypical in the realm of water-quality modeling in that they are capable of assisting with the interpretation of the data collected at a network of monitoring sites (Smith and others, 1997). Most lakes on the Gull River and Burnt River systems remain below average but are rising due to the onset of the melt. The Kawartha Lakes levels are in general below average and the drawdown is underway in preparation for the spring freshet. Burnt River reservoirs are 91% full. Trent-Severn Waterway National Historic Site, National marine conservation areas system, Directory of federal heritage designations, Frequently asked water management questions, Lake Simcoe Region Conservation Authority, Ontario Ministry of Natural Resources and Forestry, https://www.pc.gc.ca/en/lhn-nhs/on/trentsevern/info/infonet/rabattement-drawdown-forecast. Flows on the Gull remain above average for this time of year while and Burnt River flows are below average and will likely increase with the rainfall and warm temperatures. As the ice sheet is not attached at the shoreline it can be moved by windy conditions. watersheds contributing to, for example, Sarasota Bay (653 km2). The recent high precipitation event has increased water levels and as a result has moved the ice sheet on most lakes. Little snow remains in the area. Trent Severn Water Management team will be active and the changing conditions will be closely monitored. The Gull and Burnt River flows have increased due to the rain and will continue to increase. With the substantial reduction in the snowpack in the northern areas and the complete depletion on the snowpack in southern areas of Gull River watershed, most lakes are declining with exception of the lakes in the north. Flows on the Lower Trent River are above average as a result of the recent event.
