McLeod Creek is a 9.0-mile-long (14.5 km)^[2] northwards-flowing stream that begins 1.3 miles (2.1 km) southwest of Park City, Utah on the east side of the summit of the Wasatch Range. It is one of the upper reaches of the East Canyon Creek watershed in Summit County, Utah, which flows to the Weber River ad ultimately the Great Salt Lake.

McLeod Creek is probably named for long-time Park City miner and prospector John McLeod, who resided in "The Park" for about 30 years and passed away at age 67 in 1911.^[3][4]

McLeod Creek begins on the slopes of the Park City Mountain Resort between Crescent Ridge^[5] and Treasure Hill^[6] and flows northeast through Park City, Utah. It is joined by a tributary from Thaynes Canyon^[7] in the city then proceeds north where it passes Quarry Mountain.^[8] From Park City north through the Snyderville Basin^[9] there is a low topographic divide with McLeod Creek to the west and Silver Creek to the east.^[10] Silver Creek turns east to join the upper Weber River at Wanship, Utah, while McLeod Creek continues north through the South Snyderville Basin east of Snyderville, Utah, and then through Parleys Park^[11] towards Interstate 80. Shortly after crossing north beneath I80, it is joined on the right by a smaller stream named Kimball Creek,^[12] and this confluence forms the source of East Canyon Creek, a tributary of the Weber River, and ultimately, the Great Salt Lake.^[13] Note the Geographic Names Information System (GNIS) likely needs to be corrected to be consistent with the U.S. Geological Survey report and map.

From the mid-1800s through the 1970s, the McLeod Creek and nearby Silver Creek watersheds about Park City were mined extensively for silver and lead. Tailing wastes from these mines continue to pollute Silver Creek, and to a less extent, McLeod and Kimball Creeks. However, lead and zinc concentrations in McLeod Creek may still pose a risk to aquatic life.^[10]

As McLeod Creek passes between Iron Mountain^[14] and Quarry Mountain near the White Barn at McPolin Farmstead, it crosses Highway 224. There have been many deer, elk, and moose collisions at this location, highlighting its importance as a critical wildlife corridor. The organization Save People Save Wildlife has argued for better fencing and a crossing structure to protect both vehicle passengers and wildlife at this location.^[15]

Bonneville cutthroat trout (Oncorhynchus clarkii utah) is a Utah Sensitive subspecies of cutthroat trout and was the native trout species in the East Canyon Creek watershed, however it is thought to be extirpated due to decreased flows, increased nutrient input, degradation to water and habitat quality, and depredation by non-native introduced brown trout (Salmo trutta) and possibly by hybridization with non-native introduced rainbow trout (Oncorhynchus mykiss).^[16]
