An AS350B2 operated by Heli-Recon Aerial Support Services Inc., was conducting a local survey flight from Carswell Lake Camp, SK. While conducting low altitude operations the helicopter contacted the water surface of Lake Carswell in a level attitude and the helicopter was quickly submerged in the water. Both the pilot and passenger were able to egress from the sinking aircraft and swam to shore before being rescued by bystanders. It was reported that the lake water was glassy and there was reduced visibility due to the setting of the sun. The helicopter is still resting at the bottom of the lake and the operator is coordinating resources to recover the aircraft and assess the damages.
