and Coquitlam Water Works Company, were established to ensure a reliable and efficient water supply.<\/p>\n\n\n\n<p>By 1887, the Capilano River was selected as Vancouver\u2019s primary water source, with a watershed constructed 11 kilometres upstream from the river\u2019s mouth.<\/p>\n\n\n\n<p>As Vancouver\u2019s population increased, it became clear that the city would need an additional water source.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"A_New_Development\"><\/span>A New Development<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In 1905, Vancouver\u2019s mayor, Frederick Buscombe, identified the Seymour River as a valuable water resource.<\/p>\n\n\n\n<p>By 1908, the first intake was constructed on the Seymour River, consisting of a wooden pipe situated 11 kilometres upstream at an elevation of 140 metres. A second intake followed in 1913.<\/p>\n\n\n\n<p>In 1927, the wooden pipe was replaced with a steel one.<\/p>\n\n\n\n<p>In 1928, a small dam known as Seymour Falls Dam was built just north of the Seymour intake, creating a 180-acre reservoir.<\/p>\n\n\n\n<p>The dam and reservoir were expanded to their current size in 1961.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"A_New_Company\"><\/span>A New Company<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Since 1892, Coquitlam Lake had been supplying water to New Westminster. On October 18, 1902, responsibility for this supply was transferred to Vancouver Power Company.<\/p>\n\n\n\n<p>Initially, the water intake was located at the lower end of the lake. However, in 1905, a new intake structure was built.<\/p>\n\n\n\n<p>In August 1909, Vancouver Power Company secured government rights to the water within the lake&#8217;s boundaries.<\/p>\n\n\n\n<h2

Timber Company began leasing timber rights within the Capilano watershed area, initiating clearcutting activities.<\/p>\n\n\n\n<p>The logging plans became widely known to the local population by 1916, and by 1918, clearcutting was in full swing near the Capilano watershed.<\/p>\n\n\n\n<p>Investigations by Vancouver specialists revealed that logging was conducted at excessive elevations, on steep slopes, and near river mouths.<\/p>\n\n\n\n<p>These activities raised significant concerns among Vancouver residents and politicians about the potential impact on water quality.<\/p>\n\n\n\n<p>Widespread logging also led to frequent wildfires, with one fire destroying over 3,000 acres within the watershed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span

officially formed.<\/p>\n\n\n\n<p>In 1927, the government granted the district leases for timber and land within the Seymour and Capilano watersheds.<\/p>\n\n\n\n<p>By 1931, Capilano Timber Company ceased its logging operations in the Capilano watershed area.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"440\" height=\"346\"

1950s, the Vancouver Water District maintained that logging should be restricted to areas outside watershed boundaries.<\/p>\n\n\n\n<p>By 1952, logging companies began advocating for expanded operations near the watersheds, claiming it would generate significant profits and protect watersheds from potential wildfires.<\/p>\n\n\n\n<p>In December 1958, logging operations began near the Seymour watershed to clear land for a new reservoir.<\/p>\n\n\n\n<p>This project included clearing 487 acres and constructing a five-mile access road near Seymour Reservoir, generating $540,000 in revenue from the timber.<\/p>\n\n\n\n<p>In 1961, 316 additional acres were logged in the Seymour watershed to prevent aphid infestations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span

though they contained some transmission lines.<\/p>\n\n\n\n<p>From 1961 to 1992, logging roads were constructed through the watersheds, leading to extensive deforestation in old-growth forests and on steep mountain slopes.<\/p>\n\n\n\n<p>Despite hydrological studies showing otherwise, the Vancouver Water District argued that logging improved water quality.<\/p>\n\n\n\n<p>Logging operations continued until 1999, when the district decided to cease all logging activities within Vancouver\u2019s watersheds.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\"
