This large tidal range exposes sandy beaches on the shores and connects the two main islands.

In 1952, work related to flood control of the Lièvre and Outaouais rivers for the production of electricity created the reservoir, with the erection of the Kiamika dam ordered by the Maclaren company.

Stakeholders proposed, to acquire better knowledge of the territory, a study by various institutions and organizations (municipalities, development corporation, private companies and the Quebec government ministry).

In 2003, a study aimed at identifying the different potentials of the natural environment for future interpretation purposes was carried out by the Société de la fauna et des parcs du Québec.

The regulation of the water level is under the authority of the Ministry of Sustainable Development, the Environment and the Fight against Climate Change (MDDELCC), through the administrative unit of the Center d'Expertise Hydrique du Quebec (CEHQ).

[4] Located in the deciduous forest subzone of the northern temperate zone, the Kiamika reservoir offers a predominantly leafy landscape.

[4] Several types of forest species can be observed in the regional park such as sugar maple (Acer saccharum), yellow birch (Betula alleghaniensis), red oak (Quercus rubra), beech (Fagus grandifolia), etc.

[4] The Îles de la Perdrix and Île Rouge are part of the proposed biodiversity reserve established in 2008.

An exceptional forest ecosystem (EFE) of 157 hectares is also present on Île de la Perdrix Blanche.

[4] In late June, early July, blue irises (Iris versicolor) are in bloom and abundant at the eastern end of the channel between the two main islands.

[4] The southern and western sectors of the reservoir are places where we find a high density of white-tailed deer (Odocoileus virginianus) in winter.

[4] Three streams have been included in the MRCAL development plan as being of ecological interest due to their wildlife habitat characteristics.
