Water Level Status
- Low Water Level Status:
Flood Watch - April 14, 3 p.m. The Hamilton Conservation Authority (HCA) is advising of the potential for localized flooding in low-lying areas within the watershed, as a result of forecasted precipitation on Monday and Tuesday.
According to the Ministry of Natural Resources and Environment Canada, a total of 11 to 28 mm of precipitation is currently forecasted for Monday and Tuesday. The majority of the precipitation is expected to occur on Monday (8 to 20 mm) in the form of rain, with 3 to 8 mm anticipated on Tuesday in the form of mixed rain, freezing rain, and snow. No precipitation is currently expected for Wednesday or Thursday (April 16 and 17).
The forecasted air temperatures for today are +11 to +22 degrees Celsius, with anticipated daily lows of -4 to +3 degrees Celsius. The forecasted daily high air temperatures today will result in continued melting of the remaining snowpack; some snow cover still exists in various locations throughout the watershed, primarily in forested and wooded areas. The forecasted daily highs for April 15 to 16 are -2 to +4 degrees Celsius, with anticipated daily lows of 0 to -10 degrees Celsius. The forecasted air temperatures for April 15 to 16 are not expected to result in significant melting of remaining snowpack. The forecasted daily highs for April 17 are +5 to +13 degrees Celsius, with anticipated daily lows of -2 to +2 degrees Celsius. The forecasted daily high air temperatures April 17 will result in some melting of the remaining snowpack.
Water levels within the major watercourses continue to be elevated, particularly in Spencer Creek watershed. However, current water levels are below critical levels. The potential combination of rainfall and snowmelt could result in significant amounts of runoff. This may result in rapidly increasing water levels and flows in area watercourses, with the potential for localized flooding in low-lying areas. In addition, it may result in drainage issues in low-lying areas and poorly drained areas. Widespread flooding is not currently anticipated.
Lake / river ice continues to be present in some areas of the watershed, particularly in larger water bodies and Hamilton Harbour. Lake / river ice may result in further increases in water levels due to ice jams as ice break up occurs. In addition, there is the possibility of debris jams at bridges and culverts; the December ice storm resulted in a significant amount of fallen trees and branches in and along watercourses which may be carried downstream by the increased flows.
A close watch on local conditions is recommended. It is advised that people exercise caution near all water bodies, as fast moving water and slippery banks may pose a significant hazard. Adults are advised to keep children and pets away from water bodies at this time.
This message is an update to the Flood Watch issued April 10, 2014. This Updated Flood Watch message is in effect until Thursday, April 17, 2014, at which time it will either be updated or cancelled. The Hamilton Conservation Authority continues to monitor stream and weather conditions closely and will issue further messages prior to April 17 as required.
Generally indicates low flow to base flow conditions. It should be noted that during Normal flow conditions, the inherent risk to personal safety associated with flowing water still exists.
Flows are below 70 percent of their normal summer low flow. Water users are asked to reduce their consumption by 10 per cent.
Flows are below 50 percent of their normal summer low flow. Water users are asked to reduce their consumption by 20 per cent.
Flows are below 30 percent of their normal summer low flow and there is potential for economic harm to water takers and/or significant harm to the ecosystem. The Water Response Team may ask the province to impose mandatory restrictions on those holding Permits to Take Water.
No flood conditions exist.
|Watershed Conditions Statement - Water Safety
High flows, unsafe banks, melting ice or other factors that could be dangerous for recreational users such as anglers, canoeists, hikers, children, pets, etc. Flooding is not expected.
|Watershed Conditions Statement - Flood Outlook
Early notice of the potential for flooding based on weather forecasts calling for heavy rain, snow melt, high wind or other conditions that could lead to high runoff, cause ice jams, lakeshore flooding or erosion.
Flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individual landowners in flood-prone areas should prepare.
Flooding is imminent or already occurring in specific watercourses or municipalities. Municipalities and individuals should take action to deal with flood conditions. This may include road closures and evacuations.
