I have wanted a pond with waterfall for years, now I'm finally ready to start the project. My space is 13' x 28'. It's next to a raised deck and bay window with a sidewalk on the other side. A 5' waterfall would start just below the bay window heading down toward an 8' x 13' x 2' deep pond that I plan on having plants and goldfish in. That size is based on a 15' x 20' liner which is by far the most cost effective, anything larger goes up dramatically. I will need some help on filters, to skimmer or not to skimmer, pump type and size, because I want a waterfall with sound. I really love the sound of rushing water, but can't find a waterfall picture I think I would be happy with. The more I look and read I change where I'm headed a lot. I would like to start the falls so it looks like it's coming out of the house and down but I really don't want splashing water yet I want the sound of rushing water. The part that intimates me the most is trying to build the waterfall, but I can't or won't afford a contractor, I really want to do it myself. So over the next little while I will be asking for advice and suggestions on everything, but I will try and have an idea where I'm headed before I ask. Thanks in advance for the help, I'm really glad to be here, your the best sight I've found.
