Planning & Permits

If you have a stream on your property or if your lot backs onto a ravine, wetland, steep slope or the Hamilton Harbour/Lake Ontario, you are probably affected by HCA Development, Interference with Wetlands, and Alterations to Shorelines and Watercourses Regulation 161/06. Construction and development in these areas are regulated to control changes to watercourses, floodplains, wetlands and steep slopes, in order to prevent flooding and erosion problems. They are also in place to conserve the environment and its associated natural features.

Water Level Status


April 10 - 4:15 PM. Current Flood Watch Downgraded to Watershed Conditions Statement (Water Safety). The Hamilton Conservation Authority (HCA) is advising that the current Flood Watch, issued on April 8, has been downgraded to a Watershed Conditions Statement (Water Safety) message.

HCA wishes to remind residents to continue to exercise caution near all water bodies. Elevated water levels, faster 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.
Water levels in the major watercourses are elevated, particularly in Spencer Creek, as a result of the recent rainfall (approximately 28 to 50 mm of total rainfall on April 8 and 9). At this time, water levels are now cresting or have started to recede, are below critical water levels, and are not expected to pose major or widespread flooding concerns at this present time. This is based on HCA monitoring network stream and rain gauge data, as well as site observations by HCA staff.  However, some localized flooding of low lying areas that traditionally flood this time of year is occurring, particularly in Middle and Upper Spencer Creek.

Based on the short term weather forecasts, water levels in our watercourses are expected to recede over the weekend and into next week, although water levels are expected to remain elevated. It is anticipated that localized flooding of low lying areas that traditionally flood this time of year may continue over this period. According to the Ministry of Natural Resources & Forestry and Environment Canada, 2 – 5 mm of total precipitation is currently predicted for the period between this evening and the end of Tuesday, April 14.

This Water Safety message is in effect until Tuesday, April 14, 2015, at which time it will either be updated or cancelled. HCA continues to monitor stream and weather conditions closely and will issue further messages prior to April 14 as required.

Status Indicator

Normal Normal
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.
Level 1
Flows are below 70 percent of their normal summer low flow. Water users are asked to reduce their consumption by 10 per cent.
Level 2
Flows are below 50 percent of their normal summer low flow. Water users are asked to reduce their consumption by 20 per cent.
Level 3
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.
