  • Whitemans Creek and Lower Nith sub-watersheds move to Level 2 low water condition

    Water users in parts of Brant County and Oxford County are being asked to voluntarily reduce their water consumption by 20 per cent due to continued dry conditions. The rest of the Grand River watershed remains in a Level 1 condition.

    The call for the reduction came from the Grand River Low Water Response Team, which met in a conference call on Thursday. With the lack of rain, stream flows have continued to drop in the Whitemans Creek and Lower Nith sub-watersheds, prompting the team to move these areas to Level 2.

  • Update: Blue-green algae and GRCA reservoirs

    The presence of a suspected blue-green algae bloom has been observed at the beach at Belwood Lake Conservation Area. The Ministry of the Environment, Conservation and Parks (MECP) and the Wellington-Dufferin-Guelph (WDG) Public Health Unit have been notified.

    The GRCA consulted with WDG Public Health who has recommended a beach closure due to the observation of suspected blue-green algae impacting the swimming area. The beach, part of a one-acre spring-fed quarry within the conservation area, is now closed. The closure is expected to be in effect until after the algae bloom has dispersed.

  • Update: Blue-green algae and GRCA reservoirs

    The presence of a suspected blue-green algae bloom has been observed at the beach at Conestogo Lake Conservation Area. The Ministry of the Environment, Conservation and Parks (MECP) and the Wellington-Dufferin-Guelph (WDG) Public Health Unit have been notified.

    The GRCA consulted with WDG Public Health who has recommended a beach closure due to the observation of blue-green algae. The GRCA has made the decision to close the beach at Conestogo Lake Conservation Area for the remainder of the season due to a combination of factors.

  • Water conservation urged throughout the Grand River watershed

    Water users throughout the Grand River watershed are being asked to cut their consumption by 10 per cent, due to dry conditions as a result of low precipitation and high air temperatures this summer.

    Low and variable rainfall since June has contributed to reduced stream flows in several tributaries throughout the watershed, and the Grand River Conservation Authority is using its large upstream reservoirs to augment river flows to maintain low flow targets downstream.

  • Update: Conestogo Dam rehabilitation project continues

    As part of its ongoing maintenance program, the Grand River Conservation Authority (GRCA) is continuing a comprehensive project to restore the concrete of the Conestogo Dam. This project is a continuation of work completed on the dam over the last several years to repair normal damage caused by regular weather and ice events. The construction requires the reservoir to be drawn down gradually to allow the contractor access to portions of the upstream face of the dam, and then time to complete repairs.

    As a result, the West (shorter) boat launch at Conestogo Lake Conservation Area will be out of service for the remainder of the season beginning Saturday, August 23, 2025. This is due to lower-than-normal water levels for this time of year to facilitate the concrete repairs.

  • Grand River Conservation Authority to complete drone inspection and survey in Galt

    The Grand River Conservation Authority (GRCA) has engaged AECOM Canada ULC to complete a drone inspection and survey of the West Flood Protection Wall, located along the Grand River’s west bank in the community of Galt, in Cambridge.

  • Update: Blue-green algae and GRCA reservoirs

    The presence of a suspected small blue-green algae bloom has been observed at Conestogo Lake reservoir. The previous notice of a small blue-green algae bloom observed at Belwood Lake in late July, 2025, remains in effect.

  • Blue-green algae and GRCA reservoirs

    Hot summer days are great for spending time outdoors, but also create the perfect conditions for algae to grow and bloom in large bodies of water. The presence of a suspected small blue-green algae bloom has been observed near the west side of Shand Dam at Belwood Lake reservoir.

  • Grand River Conservation Authority (GRCA) urges caution around the Caledonia Dam

    The Grand River Conservation Authority (GRCA), in partnership with Haldimand County and the Ontario Provincial Police (OPP), is urging the public to obey posted rules and safety signage at its Caledonia Dam, located upstream from the Caledonia Bridge.

  • GRCA seeks public feedback on proposed changes to agricultural policy for permit applications

    The Grand River Conservation Authority (GRCA) is currently seeking feedback on proposed changes to the GRCA’s “Policies for the Administration of the Prohibited Activities, Exemptions and Permits Regulation 41/24” related to agricultural structures in the floodplain.

    The proposed changes are the result of a scoped review of policies used to make decisions on permit applications for farm buildings located in the floodplain.
