Emigration Creek

Authored by Jess Lofland

The Goshute name for Emigration Canyon is tsa’po-a, meaning “good road” [01]. The name of Emigration Creek remains unknown. Indigenous tribes hunted the canyon’s abundant fish and game. Mormon settlers arrived through the canyon in 1847 [02]. Atop, Brigham Young famously said, “This is the right place.”

Hydrologists colloquially call the canyon, “The Sponge,” due to its ability to soak up water. Groundwater is discharged at Tunnel Spring, yielding more water than the creek itself [02]. Residential properties lining the canyon, among other factors, led to E.coli impairment of the creek due to seepage in old septic systems [03].

Today, Emigration Creek flows through Wasatch Hollow, a 13-acre nature preserve. Over the years, a handful of development projects threatened the space. In 2009, a conservation easement was purchased to protect this natural space in perpetuity. Downstream, the creek flows through Allen Park, colloquially known as “Hobbitville.” The seven-acre farm was originally purchased by the eccentric Dr. George A. Allen in 1931. He built a log home, bird sanctuary, fountains, and numerous works of art, and trucked in old settler homes [05]. In 2020, Salt Lake City purchased the property for $7.5 million to protect the creek and property from development.
