The Ruins at La Colle Falls - at the turn of the 20th century, the City of Prince Albert undertook an ambitious project to generate hydroelectric energy on the North Saskatchewan River by erecting a large turbine dam. Due to some logistical and engineering problems, the project was abandoned in 1914 only five years after construction first began. The city of Prince Albert nearly went bankrupt trying to pay off the $3 million white elephant. It would take half a century to pay off the debt. Today, all that remains of the massive construction project is a concrete labyrinth on the banks of the river east of Prince Albert.
