Del Rio posted a picture he said was taken March 10th at 4 pm which shows the water level in front of the Crescent Bar property, (I've re-attached it below).
I've also attached from the same day the elevation levels of the water below Rock Island Dam, (12 miles north of the property), and for the Forebay of Wanapum Dam, (22 miles south). When the picture was taken, (4 pm according to del rio), there was less than a foot, (.59), difference between the top of the reservoir and the bottom, (plus there wasn't what I would call any type of "surge" happening in the prior 3 hours before del rio took the 4 pm picture). Therefore, my belief is that the water elevation at Crescent Bar when Del Rio took the below picture was within that .59 difference - more specifically at about 569.6 feet in elevation. (See second attachment)
There were more variables when MC's body was found, Feb. 13th. But it is likely the water level at the CB property when MC's body was found was a little less than 568 feet. I've attached the water levels from Feb. 13. (See third attachment)
If MC's feet were in the reservoir "water" when she was found, (approximate time 12:45 pm), then her body would have needed to be quite a ways out on the shoreline because the water level was likely a foot and half lower compared to Del Rio's picture below. Even in Del Rio's picture the body would have been quite visible, but on the day body found it would need to be even farther out to have feet in reservoir water.
All video news images from the Crescent Bar property were not taken on the day the body was found. Trying to use those later day images to judge where the body would be (and still have feet in the reservoir "water") would be extremely difficult. News images I've seen show the water level many feet higher than when the body was found.
Anyone who has seen a picture of the crime scene from Saturday, Feb. 13th, which shows the beach, PLEASE let me know!
