I was thinking about putting in a pond for my duck's new pen. I was planning on using a heavy duty tarp as a liner. Then I would place large flat stones around the edge to act as weights to hold the tarp in place. I was planning on using a piece of pvc pipe as a drain, but the issues with that are that where would it drain (I don't want to upset the DEP and town) and if it became blocked. I know that I could pail the water out into the garden or even use a hose to siphon the water out, but that would be difficult because of the area. I was also considering making it large enough to put in some plants and fish (large enough for the ducks not to eat, small enough for them not to be able to harm/kill a duckling.)I can't get a filter because I'm a little short on money being 15 and not old enough to have a job (not to mention no one is really able to drive me to Home Depot or Walmart to get one due to everyone's busy schedules.) I also don't have running outdoor water which means that I have to carry pails out. I do have a small stream nearby but it's downhill and dries up frequently. Here is my lovely diagram of where my duck pond will be and the stream (pardon my horrible art skills and lack of detail ) I have a feeling the stream will not help at all. Does anyone have any tips or can you share your duck ponds with me please. I know that it will probably come down to pailing out the water and refilling it. I know that kiddy pools are the most convenient, but I've always wanted a little pond for my ducks and I'm hoping that I will be able to have fish and plants in (I'm gonna guess that that will be difficult though ,but I'm stubborn like a mule.) Oh yeah I almost forgot one of the most important parts which will be the measurements of 3-4 deep (varying on the rocky soil), 8-10 feet wide and 8-10 feet long. Any help will be appreciated, thanks.
