Myrtle Falls is located approximately 6 km downstream of the Lac La Croix First Nation community. As with the High Falls Generating Station (GS), the Myrtle Falls facility will be a run-of-the-river development with an estimated installed capacity of approximately 2 MW.

The Namakan River divides into three channels downstream of Douglas Island. The main channel, which is Myrtle Falls, handles most of the river flow. The proposed concept includes a powerhouse and intake channel to the south of Myrtle Falls with an overflow weir, at the crest of the falls, to attenuate river flows.

The powerhouse will likely be equipped with a single axial flow Kaplan turbine in a pit arrangement. The minimum plant flow will be 6m³/s.  The current plan is to use this arrangement which has a narrow footprint and locate it in a natural swale on the south side of Myrtle Falls.  The proposed installed plant capacity is 2 MW, with an approximate plant flow of 60m³/s and an average annual net output of 13 GWh.

Some preliminary field study work has been performed in conjunction with the High Falls/Hay Rapids development, however, more extensive studies will be required in order to proceed with the approvals process.  It is anticipated that OPEG will begin planning the Myrtle Falls development once High Falls is under construction.
