A Report on a Statistical Model to Forecast Seasonal Inflows to Cowichan Lake.

Author:  Chapman, A., Chapman Geoscience Ltd.; Prepared for BC Conservation Foundation

Date Published:  Feb 2011

Report ID:  24293

Audience:  Government and Public

At the request of the BC Conservation Foundation (BCCF), an effort began in early 2010 to develop a statistical model to provide forecasts of seasonal inflows to Cowichan Lake. The purpose of the statistical model is to provide quantitative forecasts of seasonal inflows to Cowichan Lake based on available data, to assist Catalyst Paper (which owns and operates the weir at the outlet of Cowichan Lake) and a committee of water management stakeholders with in-season decision-making with respect to lake levels and maintenance of flows in the Cowichan River downstream of Cowichan Lake for the benefit of a wide range of community interests and resource values. Allan Chapman began the model development project while serving as Head of the BC River Forecast Centre (RFC), and completed the project subsequent to departing the RFC. This report summarizes the model, which is available in stand-alone Excel format. This project was co-funded by Living Rivers-Georgia Basin/Vancouver Island (2006-11), a program of the BC Living Rivers Trust Fund.
