Atlas of Alberta lakes is a great site and can provide alot of really useful information but it is dated. For example, the spray one has not been updated to include events like when it was drained in the 80s to clean out some of the bottom structure and do work on the dam. Apparently it was drained almost to empty and they moved fish in and out of it. Not that this is really of any significance, but just take heed that there might be some old info that doesnt apply any more. Definitely a good source of info though
