We have a beaver pond created on our acreage. It is about 1 acre in size and one pair of beavers. The water runs through a golf course before coming to our property of 30 acres. This water leaves our beaver pond under a roadway to a small stream that meanders away. Around the pond it is hilled and linded with trees of popular, willow and spruce. We have some ducks although none nesting yet. We live 60 km west of Edmonton, Alberta and it is still snowing at the moment. There is a small stream or underwater spring that doesn't freeze in the winter. Now for the questions! We would like to incorporate fish into the pond that is full of insects of all sorts and frogs. There is a considerable amount of algea during the summer but this is the first year the beavers have come back and there is much more water. (It was an old abandoned dam-pond). Also needing consideration is the fetilizer the golf course uses. Another question is how to keep the dam from backing water up into the golf couse without destroying the dam. What grasses or weeds to plant for waterfowl and birds?
