Show BATING TABLES -ISSUED.F0R1929 tVjitcr Commissioner Horace W. Kfaeley Re-ratc Canals C'dter Fedool Court Decree. The official "rating tables" of ttre j pilnctoal twenty-one canals ol tbe Uintah basin wmen are uccer the Ircderal court decree have been ie-sttd ie-sttd for 1929. Each company receive re-ceive a copy of tne rating table for Its canal ffr canals, and a copy le posted at the bead of tbe canal so Utftt any vlyi:or there can observe how high the water stands cn the GOge, Jock at the chart nailed cn the Kttge house or nearby, an.d know how much water the canal is carry- i inc. A rating table is a chart which tells bow much water passes a canal at any given depth cf water on the i;arce 'inserted therein. Hie amount of water received by a Uintah bas!n- canal 19 dependent npen these four factors: First, the "priority of its water right, which is llxed by the date of its filing with the elate engineer and the decree of j the Federal court. Second, by the area of land irrigated by the canal. I Third, by "duty of water" establish-1 cd by the board appointed for that purpose, and fourth, by the correctness correct-ness wMb which water is measured cut in accordance with the first men-ticned men-ticned three factors. yn effort has been made this year to improve the accuracy and reliability reli-ability of the measurement of water at the bto.is of the canals. In gen-cneral gen-cneral the indication of tht amount of water in the canals is made by a gage, which is an enameled metal strip par:!y submerged in the water of the canal and marked in feet, tenth of a foot, Ed hundredths of a foot. Each depth of water cn the gage cf a certain canal indicates that to much water S3 flowing by the gage. It is not the same for all canals, the Quantity of water depends upon the width o the flume or channel chan-nel tt that point, upon the grade cf the canal, and upon other thing? which not only vary among different canals but also vary somewhat year by year in the same canal. The relation between the ga.ee and the quantity cf water has been determined by a current meter. For example,, the information available ' last year for the Independent canal j ea:.d .that 1.5 feet (IS inches) of water on the gage rr.ear.t that 4 0 accord feet cf water vra going by. The carefully made rating this year j shows that when water is 1.5 feel i dees in the fume there is only 31.3 second feet going by. The Informa-! tion available last year had originat-1 ed an unknown number of years ago, and had to Le used last year because it was physically impossible for the j commissioner to cover all the canals wlib new Measurements. For that reason Mr. Sheley asked for and obtained an additional appropriation ap-propriation from the water users, tor the season of 1929, in order to secure another assistant for the part of the summer, who could devote Ms entire time to measuring the cana's, And find out how much water is passing the various gages at any depths upon them. Twenty-one canals have already been so "rated'' by 127 current-meter current-meter measurements end 17 other measurements. Some needed this re-rating re-rating very badly. Some old ratings were found to bave an error of 26 per cent, the case cl the Independent mentioned above, which proves tb it today, the same as stated in Proverbs Pro-verbs three thousand years oeo "A false niewtre Is do abomfnAttoju" In many canals there were found changed conditions which prevented Tellable masnrements, oat continuous efforts will lie saage to remove tbese |
