Due to ongoing dry conditions, water users of surface and groundwater sources within the watershed are encouraged to reduce their water use by 10 percent. In addition, it is encouraged that water users share this request with other water users. Strategies for reducing water use can be found on the resources below:
Reducing the use of surface and groundwater sources at this critical time will avoid more serious shortages in the watershed, and lessen the impact of reduced water availability on our environment. Water users reliant on the municipal water system are asked to follow any active municipal water use bylaws.
Rainfall in the last three months has been well below normal with extended dry periods, resulting in reduced flows in area watercourses. Three‐month precipitation totals for mid April to mid July were 52 to 78 percent of long‐term averages, and the majority of stations had 3‐month precipitation totals less than 70 percent of long‐term averages. In addition, 30‐day average streamflows have fallen below 70 percent of the minimum average summer month flow, at the majority of monitored stations.
As a result, as of July 27 the Hamilton Low Water Response Team has declared a Level 1 Low Water
condition for the entire HCA watershed, which includes Spencer Creek, Chedoke Creek, Redhill Creek, Stoney Creek and Battlefield Creek, Stoney Creek Numbered Watercourses, as well as all of their tributaries and other minor watercourses.
The Hamilton Low Water Response Team is made up of water users in the watershed including agricultural representatives, golf courses, nursery operators, quarry operations, and industrial users as well as provincial and municipal representatives. HCA staff act as co‐chair for this team, and are responsible for regular evaluation of watershed conditions which provides evidence to support declaring low water conditions.
A Low Water condition is declared when precipitation amounts and / or streamflow rates fall below pre‐determined thresholds, set by the provincial government under its Low Water Response Program. Level 1 is declared when three‐ month precipitation totals are below 80 percent of long‐term averages, and / or when 30‐day average streamflows are below 70 percent of the minimum average summer month flow. Level 1 results in a request for a voluntary 10 per cent reduction in water consumption by all surface and groundwater users.
It is important that we all do our part to reduce water use within the watershed.
