Show GREAT WATER POWER DE enterprise AT OGDEN li the engineering news a journal f first class repute throughout the united state we find an exhaustive tak p from W P hardesty relative to tho power development en at ogden and aa this paper ie prepared by a thoroughly competent expert and one who is pro connected with the vast un we shall endeavor to give the airport of bis article being for technical t ame and chrisee meanings that are more intelligible to abc general reader development the abeld for the development of water power hs been rapidly extending dur IBS tho put few years in all parts of the world nut only have marvelous marve loua improvement pro been made in the electrical treason of howo but the develop meat of the water power itsell has been raster lally cheapened and rendered more efficient by the invention of the felton wheel and the use of ebelt metal and wooden stave pipes for conduits carrying water under pressure all the m inn bains of the writ are of water with fill which are capable of supplying eup plying amount of power very luff of theae however are near to large cities or other place where there is a large demand for power to their development at odan utah however there is knaad in combination a large field for the tic of power with the ready means et developing and it ogden ic the prominent railway center in and ie only excelled fn size by salt like city the ogden river issues from the wasatch mountains fast east of the city and flows west through the north part of the city emptying empt yina into the river lika roost of the other streams of the ogden runs through n narrow canyon with rapid fall fora few roiley before reaching the plains the country opening oat with much leas fall and grentier ren tier eide dodea above the canyons the river has a drainage area of square miles with a yearly ann off to 24 inches of water from this baet extent of tho fall jin thie canyon spoken of is about 80 feet per mile for five miles tho requisites of ample supply of water with rapid fall for a large power are thus at hand COMPANY la november 1803 the pioneer electric power company was organized ie a utah company entirely and includes fn its directorate and man 1 firing officers the most prominent dais in tho mormon church mr 0 of aden is the chief engineer and under bis charge elior anh have been made and complete plans have been worked out tor all parts of the system in design ins the power plant and machinery he hs been ably by mr K N moree draftsman wh has had much erp orience in work of this kind POWER it is desired by the company to devel net horsepower and to do thi it will be to supplement th low water flow of the aiden river with tt orge the average low water canyon i about 14 cubic feet per second A supply of cubic feet per second is needed to develop horsepower with the fall that can be economically us d thus amnet be to aniah a flow of IlO cunic fet per sec nd for SO days in to tho low water flow alio river reaches its maxia a flow in june and its minimum is abent 1 1 choux thoux the claary under feet per leeond laota 90 days tho amount needed will 1 aquil the flow of feet per day 1 at arh leird ol 01 oddon canyon the viley widens our and the all of the alvr becomes much 1 balna only 10 fat per mile for some distance die tance and to make arro a r athral eito about 4 miles above alie bead of alo canyon ia the junction of middle and south forks of ane river A dam placed at the head cf the canyon will create a reservoir the water up alie broad main tie valleys of the forke in addition DAM s ne adam site was just within the canyon a few hundred deot below of creek which comes in from the south here thia site ia about 8 miles east by northeast from tha center of aden other sites had been examined but this was much I 1 the bast alie area to bo segregated tor lie reservoir is 1317 acres including considerable land out side of the reservoir in order to avoid irregular cuttings of landholdings land holdings this will give a storage lacity pa city of cu ft with average depth of 23 to 26 ft due allowance ie made for evaporation 18 inches being allowed for july august and september atreo months when the reservoir is most used when the loss will amount to about cubic teet the waters of tho river are cen brally fairly clear eo the deposition of will be a email bacior the total discharge of the stream during march april may and june when most adim miscarried averages 13 cubic feeland of this it ie estimated that only cubic feet is sediment based on the proportion of parts in tho site will be well cleared and rubbed the county road leading up the valley will bo changed to run above the water line TUB 1 the dani la to be of on the lines of Wag manne N 1 2 type

its length distance to bedrock bed rock ia over gofter about halt the length foundations of rabble or concrete will be carried up to the regular section the cres will be 55 leet above the low water level of the river test nits and drifts have been dug to the bottom and it is known that the maximum depth of bedrock bed rock ii about 82 feet the ends of alie dam will have alie rock ledges abutments the dam is to be of rubble masonry laid in concrete with granite facing and portland cement mortar will be used throughout the following are alia general dimensions top width 6 feet the bottom is feet broad and the lines of pressure for reservoir full and reservoir empty fall jact within ahe middle third in either case the center of erafily is 9 feet below the top and 1330 feet from the back of the wall the pressure of the water ie ibs per lin foot with water nt top of dam the weight of masonry to resist the pressure is 1 taking weight per cubic feet at 4 ibs which is rather less than the actual with conditions the maximum pressure that can come on any part of the baab is about 4 tons per equale foot alie ends of the dim are drawn in at bottom towards the stream wilb a elope of about 1 to 41 the elevation of the crest above sea level is feet WASTE WAIS there are to ko two waste ways cf 50 feet each on the dam near tho bouth end these by tie pier of a bridge which is to span them they have a clear height of feet to the top of tho dam A depth of water flowing over the crest of waste way cf feet will t cure a flow of 2300 cubic feet ond thia being about tho maximum discharge die charge cf olden river of which there ie any record if covering the remaining two feet to thelton of the dam the flow would be very nearly doubled the alone utcy in the body of the dm
