Phase 3 – Scenarios Report (5.3Mb PDF)
This report summarizes a selection of Okanagan Basin water supply and use projections for 2011 to 2040, based on Phase 3 modeling using the Okanagan Basin Water Accounting Model (OBWAM) and its supporting models, the Okanagan Basin Hydrology Model (OBHM) and the Okanagan Water Demand Model (OWDM).

Okanagan Water Allocation Tool Report (1.5Mb PDF)
In partnership with B.C. Ministry of Forests, Lands and Natural Resource Operations (MFLNRO), OBWB commissioned this report to develop a plan for an Okanagan water allocation tool, known as the OWAT. The primary purpose of the tool is to support water licence decisions made by MFLNRO.
