Mygatt.No pics yet camera is screwed up but there will be some coming. I like your depth. Here its not possible to go that deep or actually any deeper than about 6 feet unless you provide aeration as the water becomces too stratified and oxygen levels below 6 feet is pretty darn low. I pull water up from the bottom in all the ponds and keep it mixed up pretty good as well as use air pump with huge aereation stones that does a good job. Not exactly cheap ot operate year around. Water loss here is a big problem due to evaporation. My ponds are filled by rainfall and surface runoff, but these last three years this region has gfotten its last rain of any decent amount about end of April and then its dry except for a shower or two up until December or Jan, so low ponds are pretty common. The big aquatic farmers that have tilapia and catfish etc ponds all have deep well pumps so maintaining a water level lis not a problem for them so they can get by on shallower 6 feet or less deep ponds just fine. Impossible for a hobbyist to afford drilling deep high capacity wells etc.....If yur looking for good stuff for larger ponds as well as the typical backyard koi / goldfishponds checkout Aquatic Eco Systems, out of Florida, and give em a call and ask for their catalog. They have it all everything for small goldfish ponds to huge hundred acre fish grow out ponds etc........IIRC the url is aes dot com or just look for Aquatic Eco Systems on google and you'll find a website addy.
Oh and around here freezing or cold weather is not aproblem. I have seen a thin buildup of ice around the shady side of my one pond one time in 25+ years.......my water temps are still in the high 60's. So I stillcontinue to feed the fish. I stop feeding when temps hit 50 or lower and do not resume until water temps go back up above 50 deg for at least 10 days in a row... Looks like this year I get to feed all year...
I love fish !
