The park was created on April 30, 1996 as a result of recommendations made in the Kamloops Land and Resource Management Plan.
Cultural significance is associated with the historical use of the river, evidenced by the many kekuli pits (semi-underground pit-houses) on the island. Historical use by the Neskonlith Indian band.
The island is long, narrow and vegetated with ponderosa pine and grassy undercover. It is a significant waterfowl nesting site, especially for Canada geese and also for osprey and bald eagle, and wintering habitat for tundra and trumpeter swan. The downstream end of the island is also near spring salmon spawning grounds.
Nesting waterfowl are found here from April to July, with nesting raptors from spring until August.
