Hi Guys, I saw some posts with interest in intake bays and thought I would share my idea. My garden pond is roughly 8' x 18' and 3' at the deepest, about 1500 gallons (I didn't count). I'm using a 3' deep by 4' wide by 6' long intake bay. At the mouth of the bay are larger shelved stones that create velocity into the bay and the water level is the same as the pond level. I dug a mini trench, roughly 5" by 5", lengthwise, along the bottom of my bay. I used upside down milk crates instead of the commercial brand "boxes" over the 4", roughly 4' long, PVC drain pipe I installed in my mini trench, double stacked, side by side. The 4' pipe connects to a 27 gallon food grade PVC shipping barrel through use of a bulkhead fitting. Think "dry well". Over the entire sides and surface of the milk crates, and around my drum, I filled with 3" river stone. For about the last 3-4 inches of fill, I used 3/4 smooth stone. I have about 8-10" of free flowing water over all my fill. The top of the drum was left accessible. In the drum is my 6000 GPH pump. I cover the top of the drum with its cover and a large flat stone. I probably could have added some sort of filter material at the bottom of my drum but solids don't reach the pump. On the input side, I used a 5' X 6' bog using a similar method. So far, so good. I only have about a 2' lift and there is no added strain on the pump with good flow. It works!
