I was on this call... coming back from kayaking in island park the call comes out possible drowning, diver support needed west boat ramp American Falls Resevoir. this was a multi county assist by this point..
When I arrived power county had been workin on the call for a couple hours. and I think the sheriff did an excelent job. after all four men went down, the boat drifted quite some time until the kids called 911 and reported the accident. Power county went out and gps the location of the boat and got the kids to safety. then began a surface grid search up wind from the boats cooridanats. during that search they found a life jacket believed to have been taken overboard by one of the victims and a leather hat floating that was believed to be on of the victims. They dropped bouyes on both locations and from that Decided that this is a probable course the boat traveled away from the drownings.
We put bouyes every so often and dropped them doing circle patterns and just started "eliminating bouyes" Conditions were typical august in SE idaho resevoir was 51 feet deep, 65 degrees and no visibility.. I could see my computer illuminate but could not read it. We were pre briefed that if we found a body to mark it with a pellican bouy and leave it on the bottom, because it was believed that all four bodies would be lying close togather and that would give us a more close proximity area to search for the other 3.
after a day and a half of searchin with no luck the Side scan unit from boise arrived and went to work. That is one nice peice of equipment!! its like watching a tv program of the bottom of the lake is what one marine deputy told us. they located all four bodies and bingham and power county divers went and bagged them and brought them to the surface.
Its a tragedy how four ppl having fun on a sunday afternoon can go so badly so quickly. 5 little kids watched as their family and loved ones drown and dissapear in a body of water and drift in horror, not knowing what to do. Several of my friends were friends with one of the four who drowned and alot of SE idaho is in shock over the incident. its sad but thank god the count stopped at four and all the kids stayed safe while they went on thier venture after the tragedy.. tryin to be optomistic about it
side note... this information is not via Bingham county, it is just what I saw and heard on the search.... for educational purpose only
