My Fish have done great , 2021 - July 2023 , the rains came , Filled my upper Canyon Pond after expansion from 1/4 Acre to 1.8 +/- Acre Pond with Average depth of 12FT , lots of Holes through out the Pond exceeding 16FT , Western Oklahoma is drought country , so depth was critical. Only 2 run off rains in May of 2025 , neither was really big , but brought water up to normal pool after reaching Spillway pool July of 2023. Today , the water is 6' down from Just normal pool and 10 - 11FT down from spillway pool , watershed is 38 - 42 Acres of good tight mowed native grasses that with mowing have grown tighter and entire pond is ringed with mown bermuda grass that is incredibly tight , the runoff is clear , nearly zero trees . Fortunately , even without runoff , we've gotten 1/4" - 1/2" showers every 2 weeks or so that have maintained the grasses . This upper Pond is now in danger , Secchi shows 16" - 18" visibility for 2 weeks solid now , in 24 hours it went from 32+" visibility , a beautiful gem stone tsavorite green , to a dull , thick looking , green . I've been saving pennies for 4 years to purchase a Bottom Diffused Aeration system and am approaching the cash to do it , but with this toilet bowl , under todays conditions , is the typical Bottom Diffused what I need ? OR , Today is a Trash Pump or two what I need ? Pull water from 3ft down from one of my fishing piers and run 100' - 200' of discharge line to another Fishing pier and let water fall 7 - 9FT into the pond and start a loop of circulating water . I have 4 Fishing Piers , 2 on south bank ( 1 with 120/240VAC ) and 2 on North Bank , same power available . TYIA , for your Thoughts. Fortunately , the Lower Canyon Pond is hanging on , with fairly clear green water , guessing 28" - 34" visibility . It doesn't have the fishing piers for access .
