61 <br /> 1 days. So a cfs is a cubic foot per second. 4 cfs is 1 you bad occasion to observe what was happening at the <br /> 2 approximately 1,800 gallons a minute, and for 30 days 2 pond? <br /> 3 that's approximately 7,700 -- 77 million gallons of j 3 A. Yes. Yes. So I was out there in late <br /> 4 water. I do think it was more like 238 acre feet, 4 May over Melorial weekend, and we had water running and <br /> 5 which is another conversion, gallons and cubic feet. 5 filling up the pond and the irrigation system in 2014. <br /> 6 238 acre feet or so, an acre of water 6 Q. Did you ever observe the pond <br /> 7 stacked 283 feet high. 7 overtopping? <br /> 8 MR. SINGLETARY: Tell me how you 8 A. No, no, no. The pond doesn't overtop, <br /> 9 calculated that. 9 and the pond is actually a structure in the irrigation <br /> 10 MR. CAREY: So the calculation is cubic 10 system. The issue out there is that there's cliffs <br /> 11 feet per second is -- is the amount of water per 11 wrapping the property there, and so any kind of a <br /> 12 second. 12 return water we have to capture from the pond to try <br /> 13 MR. SINGLETARY: Right. 13 and prevent it running over the clips and dam on to <br /> 14 MR. CARET: And I can give you the 14 I-70. <br /> 15 actual. So times -- so that amount of water times -- 15 And so the pond helps capture and <br /> 16 let me give you the actual days. So in 30 days -- in 16 infiltrate that water and — and keep it from running <br /> 17 30 days there's actually 2,592,000 seconds, and so 17 overland down to I-70. It's part of the irrigation <br /> 18 that — then at 4 feet -- at 4 cubic feet per second, j18 system that's always been there. <br /> 19 that equates to 10 million. ; 19 Q. Is that also designed to keep water out <br /> 20 MR. SINGLETARY: Or about 8 foot a day? 20 of the Colorado River, this irrigation water? <br /> 21 MR. CAREY: Yes. You're right. So 21 A. Well, it's -- it's really designed to <br /> 22 another way to convert it is 1 cfs is approximately 22 try and keep it from running dam off the cliffs -- the <br /> 23 1.98 acre feet per day. So 4 cfs is approximately 8 23 Colorado River is down beyond the highway there -- and <br /> 24 acre per day. 8 acre feet times 30 days is 240. 24 into the water. <br /> 25 MR. SINGLETARY: Gallons are an 25 Q. Were you ever asked to turn off the <br /> 234 236 <br /> 1 illusion. You know what I mean? It's a nice way of 1 irrigation water? <br /> 2 saying a lot of water. But I want to know the acre 2 A. Well, I wasn't asked specifically, but <br /> 3 feet, so -- 3 Rudy Fontanari, he manages the ditch. He's our ditch <br /> 4 MR. CAREY: Yeah. So 240 acre feet 4 manager, and he -- he was asked to turn off the water. <br /> 5 approximately, using round numbers, was applied, and-- 5 Q. What were the circumstances? <br /> 6 but that does equate to 77 million gallons, and that is 6 A. My understanding was that there was <br /> 7 relevant because of the amount of gallons -- and we'll 7 water coming out of the portal, and there was a concern <br /> 8 get to that -- because we've used gallons earlier to 8 of the safety of the -- of the mine. <br /> 9 talk about 10,000 gallons being applied to the -- to 9 Q. Was the county sheriff concerned about <br /> 10 the testing procedure. 10 this? <br /> 11 Q. (BY MR. STUTZ) Well, haw many acre feet 11 A. Yeah. My understanding was that <br /> 12 were applied in connection with the testing -- 12 everybody was concerned about this as a safety issue <br /> 13 A. I'm not sure I can calculate -- 13 that potentially -- <br /> 14 Q. -- based on your -- 14 Q. What were they concerned might happen? <br /> 15 A. Let me try -- 15 A. Well, I think there was uncertainty, but <br /> 16 Q. -- being here during the hearing? 16 I think that they recognized that water was building up <br /> 17 A. All right. Let me just -- if you don't 17 in the mine and that potentially if water came out of <br /> 18 mind me running a quick calculation. 1e the mine in a rush, it might flood the highway or cause <br /> 19 (Pause.) 19 flooding problems downgradient. <br /> 20 So approximately 10,000 gallons is about 20 Q. Prior to that, would it be blowing out <br /> 21 1,336 cubic feet. 21 the structure that held the water back into the mine? <br /> 22 Q. Is that more or less than 1 acre foot? 22 MR. JUSTUS: Objection. He's requesting <br /> 23 A. It's less. It's about 3 percent of an 23 speculation on operation engineering with respect to <br /> 24 acre foot. It's about 3 percent of an acre foot. 24 mining, reclamation, and otherwise, saying "blowing <br /> 25 Q. Now, while the irrigation was turned on, 25 out" this. This is also undisclosed expert testimony <br /> 235 237 <br />
