Description

Twin Valley Reservoir was first filled in 2003 following construction of a new dam on the Little Bow River near its confluence with Mosquito Creek. To fill and operate the new reservoir, increased diversion from the Highwood River to Women’s Coulee and to the Little Bow River occurs in spring according to an approved water management plan. An existing lake, Clear Lake, was also stabilized by diversion from Mosquito Creek near the mouth first operated in 2002, and additional enhancements. This report presents an evaluation and statistical analysis of water quality in Twin Valley Reservoir, Clear Lake, and their tributaries that was prepared using intensive monitoring data collected by Alberta Environment from 1999 to 2010, with reference to previous baseline sampling where needed for statistical testing.

Description

The purpose of the literature search is to review and comment on the available information on particulate matter source emission profiles and source apportionment methodology, and to identify data gaps that may require further field studies. This report has two parts. The first part presents a detailed description of the sampling and analytical methodologies, while the second part concentrates on a brief description of the common apportionment studies with emphasis on the chemical mass balance, and a compilation of source apportionment studies performed in Canada and around the world.
