Indian Creek is a long tributary of the Boise River in Canyon, Elmore, and Ada counties in Idaho, United States.
Beginning at an elevation of south of Arrowrock Reservoir and north of Mayfield in western Elmore County, it flows west into Ada County and through the town of Kuna.
Indian Creek is dammed at Indian Creek Reservoir, visible from the I-84 freeway east of Boise. Below the reservoir the creek is mostly dry, but several more small dams pick up the small drainage to form stock or irrigation ponds.
Kuna Section:
East of Kuna near Eagle Rd, the New York Canal fills the creek bed between March and October, creating its largest free-flowing section. This section is often used by floaters, and runs through the town of Kuna, next to parks and a short green belt path. West of Kuna near Columbia Rd, the water is diverted back into the lower section of the New York Canal, which flows west into Lake Lowell. The creek bed continues to the northwest.
The creek bed fills again from local drainage as it flows northwest into Canyon County, through Nampa, and then Caldwell, where it flows past the Indian Creek Plaza, before continuing north to its mouth, where it joins the Boise River. At an elevation of . Indian Creek has a watershed.
