If boating at night or in low light conditions, navigation lights that meet the applicable standards set out in the Collision Regulations. If the pleasure craft is operated after sunset and before sunrise or in periods of restricted visibility (for a canoe), a single light is sufficient (e.g. waterproof flashlight, lantern or torch).

When looking at the Alberta Environment flow reports for a particular station be sure to compare the reported flow (table) with the annual graph (figure) of flows for that stream and station.
