Las Vagan - March 16, 1943 W 23-3-3 Mr. Frank Strongs fair tceasureraente war® made of the production of tha wells and springs yesterday, and 1 am attaching hereto the result thereof, together with a re-statement of the May 5, 1942 measurements for ready comparison. You will note an Increase of almost half a million gallons per day. The weir boxes for the Big Spring and Well No. 2 are very well set with a straight run of at least 50 feet prior to passing over the weir, as recommended by State Engineer. However, the weir box for Well No. 1 is too close to the well and appears to be too short so that the velocity of the water distorts the reading. We measured ?| inches on this weir box but this was obviously incorrect, so we checked it with a still pond and found ? Inches even which we have shown in the attached table. The same difficulty is apparent at the weir box for Well No. 6. This might be remedied in a measure if the overflow pipe were trained in at the bottom instead of the top of the weir. I understand there are three pumps on hand here, Intended for Wells No. 4, 7 and 9. No. 9 is now producing over a million gallons per day and In-as-raueh as it has a metal derrick it would probably be much better to move the derrick over to No. 10 and Install a pump therein; or if this is not desirable it could better be used on No. 8. The Wallace & Tlernan repreeentatlve is here today to install the chlorinator In pump house at Open Spring. If it has been decided to go ahead with this installation, I think it is very important that the line be thoroughly cleaned out thru weir box at settling basin and samples sub­mitted for bacteriological analysis before the production from this source is allowed to get into the City mains. This is extremely important and X trust there will be no slip-up on the part of our employees. WOTSiri;.B M ' i
