Project Description:

This project will build on previous work by Okanagan Nation Alliance (ONA) and Okanagan Indian Band (OKIB) in the Browns Creek area (Whiteman and Naswhito creeks) to help manage and conserve aquatic resources for future generations. The project will produce high value stream mapping of the focal watersheds with spatial representation of existing aquatic resources in addition to the location and function of existing Large Woody Debris (LWD) clusters.

LWD naturally performs and recuits many processes important to a healthy stream ecosystem. Additionally, they introduce resiliency within a watershed to persist during drought and/or flood by creating complexity in the stream channel. However, their presence can introduce risks when there’s a dynamic response to high flows with their mobilization or alterations to stream flow during flooding which can cause lateral channel movements, sediment release or damage to infrastructure.
