Welcome to Joseph Creek: A Community Effort in Restoration

Joseph Creek, flowing north from Joseph Mountain through Cranbrook and into the St. Mary’s River, is an important waterway with a rich story. This creek was historically recognized as the most significant juvenile Westslope Cutthroat Trout recruitment stream in the lower St. Mary River drainage, serving as both a vital fishery resource and a cultural gathering place for the Ktunaxa Nation and the Aq’am people. See a map of the creek.

The creek's historical significance surged in 1898 when the Canadian Pacific Railway established the Crowsnest Pass line, leading to the development of Cranbrook, which was incorporated as a city in 1905. Since that time, Joseph Creek has taken on many more roles: it has been a drinking water source, a stormwater management system, and a recreational area. In the 1920s, the creek was dammed to create the Idlewild reservoir, becoming the city’s primary drinking water source until the mid-1970s, when the Phillips Reservoir, located south of Cranbrook along Gold Creek Road, became the main source of drinking water. Both Gold Creek and Joseph Creek supply this reservoir.

Today, however, the health of Joseph Creek is compromised due to years of urban development, sedimentation, water usage, invasive species, habitat destruction, and channelization. Numerous studies and reports have documented the creek's ecological health and identified factors influencing its decline. While these reports often recommend restoration strategies for specific species, they frequently fail to consider the multi-dimensional effects on the creek or the community's cultural values and infrastructure needs.

In response to these challenges, various local organizations and groups have sought to improve the creek over the past several decades. While these efforts have been well-intentioned, they typically focused on isolated issues related to specific species or ecological impacts. Now, the community is embracing a more integrated and collaborative approach to restoration. Residents, scientists, and diverse organizations are coming together to implement comprehensive strategies that address the health of the ecosystem as a whole.

Efforts include clean-up initiatives, habitat enhancements, riparian restoration, park developments, and educational programs aimed at reconnecting residents—particularly children and youth—with nature. In an era where technology and urbanization have distanced many from the outdoors, there is a renewed interest in fostering a connection to natural spaces. And as our population ages, many are reflecting on their experiences with the creek and expressing a desire for future generations to value and enjoy it.

Together, we are committed to revitalizing Joseph Creek, ensuring it thrives for years to come. Join us in this essential effort to restore our aquatic gem—because a thriving creek enriches the entire community.
