Bill... you were right. Some of the logs are floating.
Not much I can do about it other than hope and pray that a few of the bigger ones stay in place. Tire pyramids and cinder blocks would have definitely been a better choice.
For anyone interested... I've attached updated photos. I'm at about 1/3 to 1/2 full pool in these photos taken 2-3 weeks ago. With the recent rains, I'm hoping to see a 2/3 full pond when I drive up this weekend.
More background... besides the 5" rain we got a month ago, we drilled a 500 ft water well and I buried a 1 1/4" Sched 40 PVC pipe from the well, over the levee and to the pond. The water cascades over some limestone rip rap to aerate it a bit before it trickles into the pond. The pump is rated to 30 gpm. The well jetted 50 gpm for 2 hours after it was completed with about 7ppm total iron.
After six weeks of 24/7 pumping, it started cavitating so I had to back it down. Right now, I've got it cruising along at about 6-8 gpm.
I also tested the water after we drilled the well.
Original Pond - pH = 7.0; Alkalinity = 20
Well Water - pH = 6.5; Alkalinity = 60
It's holding water so far and I don't want to jinx it but guess I need to start thinking about stocking it now.
