Early in the 20th century, the dam was rebuilt to aid in water storage for the production of hydroelectricity, intended primarily for use by the mining industry. While it did serve this purpose, the dam also proved invaluable in flood mitigation on the Wahnapitae River. Moreover, it created numerous recreational and economic opportunities for area residents, businesses and so forth. Having taken ownership of the Lake Wahnapitae dam and the three hydroelectric generating stations on the Wahnapitae River between 1929 and 1930, the Hydroelectric Power Commission of Ontario (formerly Ontario Hydro and now Ontario Power generation - OPG) also took over the responsibility of water level and flow management for the system. Much of what occurs with respect to water levels and flows on the Wahnapitae (or any other watershed for that matter), is determined by variables such as precipitation, temperature, topology and geology. Working in close conjunction with the public, area businesses, First Nations, the Ministry of Natural Resources (MNR), Fisheries and Oceans Canada (DFO) and many other regulatory agencies, and by carefully tracking water level and flow trends over the years, OPG has been able to employ a reasonably balanced operating regime to exert a degree of control over the Wahnapitae system: one of its primary objectives being flood mitigation. This current regime, or Water Management Plan (WMP), incorporates a myriad of environmental, social and economic values of importance to these individuals and groups. It has a variety of water level and flow constraints – most of them voluntary - that take into account the multiple uses of the river, while ensuring the structural and operational integrity of the dam site and generating facilities. The watershed’s newest hydroelectric generating facility– Moose Rapids generating station, owned by Canadian Hydro Developers Inc. – has only negligible control over the water levels and flows on the Wahnapitae River. Even so, it was built only after a detailed environmental assessment was undertaken to analyze the effects that this structure would exert on the surrounding ecosystem. Complex studies were conducted and many measures were implemented to ensure that Moose Rapids GS would have as little impact to the site as possible. In 1998, the Ontario Government passed the Energy Competition Act in order to establish a competitive electricity market in Ontario. With an open electricity market, and new private producers vying for a share of it, it was feared that voluntary level and flow constraints could make way for operating decisions that were overly sympathetic to the economics of power production. Thus, in 2000, the Lakes and Rivers Improvement Act (LRIA) was amended. It established the authority of the MNR to order the preparation of a formal WMP for waterpower facilities and associated control structures that would ensure legal compliance to water level and flow regimes: hence the necessity for the development of a new plan for the Wahnapitae. The goal of the Wahnapitae WMP is to develop a water level and flow management strategy for the Wahnapitae Lake and River that builds on the current operating regime for the system. It will attempt to balance environmental, social and economic considerations through the sustainable management of waterpower resources. The plan will be prepared according to the Water Management Planning Guidelines for Waterpower (May 2002) and other applicable direction, such as the Aquatic Ecosystem Guidelines, and will result in a comprehensive, legally enforceable WMP. Extreme events such as drought and flood conditions will be defined in the WMP by specific thresholds, in which case other applicable protocols and procedures will be followed. Public and stakeholder participation and input is highly valued by the MNR, OPG, Canadian Hydro Developers, Public Advisory Committee and Wahnapitae First Nations and is believed to be of utmost importance to the development of the final WMP. It is paramount, therefore, that the public clearly understands water management on the Wahnapitae. For this reason, the Wahnapitae Planning Team, Steering Committee and Public Advisory Committee have attempted to compile a scoping report that is straightforward and uncomplicated . Hopefully, it will encourage informed citizens to present issues and concerns regarding water levels and flows in the Wahnapitae watershed, that will ultimately contribute to a more complete and effective Water Management Plan. 3 Scoping Report For The Wahnapitae Water Management Plan (WMP) A formal, written, legally enforceable procedure
