Inquiry (采购产品): pond riser fabrication Do you folks sell risers for farm ponds. I need one about 12' high with a valve in it to lower the water level. The pond is about one half acre in size. I am replacing a corragated metal one that has rusted out. **** Hidden Message ***** Bob Perkinson 24701 Company: none E-mail: perkinbob@yahoo.com **** Hidden Message ***** perkinbob@yahoo.com
