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 document was developed with the intention of providing leading practices to help operators optimize the use of available reclamation materials on a site-specific basis. The best management practices (BMPs) contained in the document are provided as background to aid operators with current and planned reclamation activities to enable continuous improvement. BMPs provide a reasonable level of guidance on practice for activities representing moderate risk and are based on imperfect knowledge. When using this document it is important to think about interactions between individual BMPs, as well as the BMPs and external factors.
