Elwin, tell us a little more about it. Where is it ? How big is the dam and the
pond ? What materials were used ?...
I don't see any emergent plants like cattails and
water lilies. Do you actively discourage an emergent zone ?
What sorts of fish and other life does it contain ?
When you build a dam, your work goes a long way since you can lay claim to the dam itself and to the
pond that nature shapes as a result.
edit --- I see your other
thread relates to this. You may have created this new topic in error when you really wanted it added to the other one. If so, one of the more attractive stewards may fix it for you. Here's the link ---
