DRAFT EXECUTIVE SUMMARY Matrix Solutions Inc. was retained by the City of London (the City) in March 2018 to complete an Environmental Impact Study (EIS) to support the Municipal Class Schedule B environmental assessment (EA) for the decommissioning of the Springbank Dam. The Schedule B Class EA is being conducted as part of Stage 2 of the One River Master Plan EA. The Schedule B EA was initiated by the City, after the completion of Stage 1 of the Master Plan, upon confirmation by city council in January 2018 that Springbank Dam will not be re-instated. The preferred dam alternative has been defined as the partial Dam removal, involving the removal of some dam components, while retaining the remnant dam structure to allow for a free flowing river system. The EIS describes the significant natural heritage features and functions within the Study area, and identifies what potential impacts the preferred alternative may have on the significant features and functions. Based on the assessment, the EIS recommends strategies to avoid or mitigate the potential impacts which are incorporated into the project approval. The EIS combines relevant background studies with information gathered from ecological field studies to characterize the natural heritage setting and identify significant features within the Study area. The results of the significance and sensitivity analysis indicated the presence of several natural heritage features and functions including Significant Valleylands, Significant Wildlife Habitat (SWH), fish and aquatic habitat, and Species at Risk (SAR) within the Study Area. The potential effects that may be caused by the implementation of the preferred alternative (i.e., partial Dam removal) were evaluated against the identified natural heritage features. The results of the assessment indicated that construction activities, along with construction access, staging, and vegetation clearing, are expected to have localized temporary effects to the natural features. The partial Dam removal is anticipated to have a beneficial long-term effect on the Study Area. The more stable naturalized banks provide shade and refuge for terrestrial and aquatic species. The removal of the gate(s) will improve fish passage between the upstream and downstream aquatic environments surrounding the Dam. The long-term effects associated with this project are expected to improve the natural features, functions, and the overall connectivity of the Thames River Corridor. Mitigation measures provided in this report are recommended for consideration during project approval. Given the presence of multiple SAR within the area, it has been recommended that consultation and permitting through the appropriate authorities be obtained before any construction work. This document was reviewed by Matrix Senior Ecologist, Arnel Fausto and review comments and recommendations have been incorporated into this report. 24504-528 Springbank Dam EIS 2019-03-29 draft V0.3.docx iii Matrix Solutions Inc.

ABSTRACI': The WeI/and River watershed drains an area of 880 km2 and is part of the Niagara River Area of Concem. As one step towards remediation, the Universal Soil Loss Equation (USLE) was used to estimate soil erosion inputs to the river from each of the 34 sub-basins in the watershed. An innovative approach using risk and uncertainty analysis was incorporated into the conventional USLE estimates in order to address concems about uncertainty due to the variability of the USLE parameters across the WeI/and River watershed. This paper describes the methodology for the statistical approach to the USLE and those sub-basins with high potential soil loss were identified. INTRODUCflON (USLE) was used to estimate soil erosion rates for each of the 34 sub-basins in the watershed. A risk and uncertainty analysis (including probability The Welland River watershed is part of the distribution fitting and simulations using Latin Niagara River Area of Concern.

  • Central Welland River Watershed Plan
    CENTRAL WELLAND RIVER WATERSHED PLAN NOVEMBER 2010 NIAGARA PENINSULA CONSERVATION AUTHORITY RD 250 THOROLD ROAD WEST, 3 FLOOR WELLAND, ONTARIO L3C 3W2 (905) 788-3135 www.npca.ca CENTRAL WELLAND RIVER WATERSHED PLAN Executive Summary The Central Welland River watershed is a unique watershed for many reasons. The rich history of the Welland Canal has influenced and shaped the cultural and economic history of the area. The patterns of land use in the region are a result of the early construction of the Welland Canal and the strategic location of settlements and industries that took advantage of the accessibility to markets flourished throughout the last century and a half. Aside from being rich in cultural history, the Central Welland River watershed study area is also rich in ecological diversity with 3 unique and provincially significant Areas of Natural and Scientific Interest such as the Wainfleet Bog and the Fonthill Kame-Delta Complex, as well as an additional 5 more regionally significant ANSI‟s. The study area also boasts 27 listed Species at Risk by the Committee on the Status of Endangered Wildlife in Canada, including the eastern massasauga rattlesnake which is the only venomous snake in Ontario. In addition, 17 provincially rare species, numerous provincially significant wetlands and natural areas can be found throughout the watershed. The study area extends within the boundaries of the Township of West Lincoln, Town of Pelham, City of Welland and small portions of the Township of Wainfleet and City of Port Colborne. Numerous subwatersheds form the Central Welland River watershed including Beaver Creek, Black Ash Creek, Parkers Creek, Unnamed Creek, Sucker Creek, Coyle Creek, Drapers Creek, Little Forks Creek, Lyons Creek Drain, Indian Creek Drain, Biederman Drain #1 and Biederman Drain #2, as well as Welland River Between Canals, Welland Canal and a portion of Welland Canal North (Figure 1).
