Millionaire Creek is a high-value fisheries stream in the Silver Valley, Maple Ridge, British
Columbia. It is one of the largest tributaries to enter the Alouette River, and
drains the southern sections of the UBC Research Forest and Golden Ears Park.
Until recently, the watershed was relatively undeveloped with just some hobby
farms in the lower reaches. A large residential development plan was proposed
for the area in the late 1990s, and development proceeded during 2002 to 2004.
In 2000, the Ministry of Environment (MoE) initiated a water quality monitoring
program in Millionaire Creek to assess non-point source impacts from urban land
use. As part of this program, an automated water quality monitoring station was
installed in late 2001. In 2004, MoE contracted Aquatic Informatics Inc. to review the data collected to date, to validate and correct the automated data, and to recommend water quality objectives for water temperature and turbidity that recognize both magnitude and duration.
The objective of this Summary Report (PDF/1.02 MB/30 pages) is to recommend magnitude-duration based temperature and turbidity Water Quality Objectives for Millionaire Creek.
A discussion of assessment methods used in the above-described summary report can be found here (PDF/1.70 MB/56 pages).
