The Parkavera River was a naturally occurring water course that branched off the St Clare River parallel to the Madeira River thus forming Madeira Island. The Parkavera and Madeira Rivers re-joined each other and the resulting river flowed back into the River Corrib near to where it flows into Galway Bay. The water power from both of these parallel rivers was used to drive several businesses over the centuries including a brewery, a saw mill, a paper factory, a rectifying distillery, and a foundry.
