The Barrie Creeks, Lovers Creek and Hewitt’s Creek Subwatershed Plan 5.3 Factors impacting status - stressors There are a number of land uses, activities and other factors that can have an effect on the health of the aquatic community in the subwatershed. These include: • Barriers, • Bank hardening and channelization, • Enclosures, • Flow diversion, • Uncontrolled stormwater and impervious surfaces, • Municipal drains, • Removal of riparian vegetation, • Water quality and thermal degradation, • Loss of wetlands, • Invasive species, and • Climate change. These factors are discussed in detail in the following sections: 5.3.1 Barriers Barriers to fish movement in the form of dams, perched culverts, and enclosed watercourses serve to fragment the fish community by preventing fish from accessing important parts of their habitat. The impoundments created by dams serve to increase water temperatures, raise bacteria levels, and disrupt the natural movement of fish, benthic invertebrates, sediment and nutrients. The natural movement of each is imperative for a healthy aquatic system. The Lake Simcoe Basin Best Management Practice Inventory (LSRCA, 2009) looked at barriers to fish movement, which included dams, perched culverts, weirs and other barriers, and sections of the bank that have been hardened or channelized. The BMP inventory covered 92%, 76% and 100% of the watercourses in the Barrie Creeks, Lovers Creek and Hewitt’s Creek subwatersheds, respectively. The BMP Inventory has identified 40, 56, and 3 barriers to fish movement, respectively, in the Barrie Creeks, Lovers Creek and Hewitt’s Creek subwatersheds thus far (Figure 5-8).
