ASHBURTON COUNTY COUNCIL., Ashburton Guardian, Volume 2, Issue 313, 7 April 1881
ASHBURTON COUNTY COUNCIL.
We resume our report RAKAIA BRIDGE QUESTION. Ou this matter being brought up again, Cr Wright moved —“That the whole matter be referred to a committee, consisting of Messrs Grigg, Saunders, Bullock, the Chairman, and the mover, to prepare a reply to be submitted to the Council at a special meeting, and, that the deputation be informed that a reply will be sent as soon as possible.” This was seconded and carried. engineer’s report. The Engineer’s report, which was as follows, was read : 1. Road Pudding Hill.—The road leading from the terrace into the river bed above the dam is about half completed. This road is in substitution of the old track to bush, which was cut off by the formation of the head works of water supply. 2. Chapman’s Creek Extension. The cutting of this new channel is in progress’ as far down as the West (.’oast road. 3. Protection Chapman’s Creek.—That portion of the creek directly above Diayton which was mod liable to scour, to the extent of six chains, has been secured with stones and clay, and the amount of absorption there is now materially diminished. A few more places on tills creek will require to be treated in a similar manner, as will also, a portion of the new cut at Mount Harding and these works will be put in hand next week. 4. Bridges and Culverts. The Water Supply Committee having approved of the proposed junction of, lines at Methven, the cu'vert at cross roads there is now being put in place, and is of sufficient capacity to take the supply required for the present test channel, and also the proposed channel leiding past Chertsey. All the bridges for public roads oh this line of test channel have been completed' during last month. 5. Water Races—Ashburton and Rakaia Plains.—The present test channel is still serving its purpose satisfactorily. There is very little - change either as regards scour or percolation since the date of my last report. As to the proposed new races, in compliance with the Council’s instructions, I examined the various districts, and laid down on the map such lines as appeared to combine suitably in. point of gradients with efficiency of service to greater parts of the holdings in .the various districts. These lines the Committee have in the main approved cf, and the routes as fixed by them are shown in the blue lines on th accompanying map. The loop-lines shown in. red pencil are the auxiliary lines which the Committee recommend to be made only after all the main races are formed, and if there should be water enough remaining to supply them. [Detailed particulars of the lines and directions thereof were here included.] I beg to annex detailed estimates of these various lines, including- earthwork, bridges, culverts, tanks, &c., of which the following is ah abstract:— line. Direction. Length. ■ Cost, A Next Ashburton river miles ,£"BS B Passing Dromore 31 ~ 905 Bi (Loop-Line) ~ 260 C (Extension of) 4 ~ 155 D Passing Chertsey 30 ~ ■/ 99S Dl (Loop-Line) 9 «> 3*5 L2 (Loop-Line) ' 9 ~ 155 E Next Rakaia river 39 1,670
Total ... 148 .£5,240 I would beg to suggest that if the Council agree to execute these main lines, either the dine; passing Dromore or that passing Chertsey be the first to be put in hand, and either of these lines to be let in three contracts. One line of 30 miles is about as much as could be slaked out and efficiently supervised in one vrioiith, especially as where the channels do not follow road lines , the routes will have to be clcsely staked out, and levels taken in many instances. At this rate the .whole extent of open races proposed would be completed in five months. 1 jnay state that several, owners; are preparing to'lake advantage of the facilities afforded for leading water, under arrangements, from the water race to their tanks. At the slaughter house at Methven it will be necessary to alter the line of creek for a few chains, in order to escape the contamination arising from the offensive ma'ter spread over the' ground there. ■' 6. Hinds-Rangitaia Wafer Supply.—With a view to determine the pi open source for supplying the district between the Hinds and Rangitata, I have examined.the river bed and banks of the Rangitata river from the railway line up' to the Gorge, a distance of about twenty-six miles, and I am satisfied that there; is no reliable site in the river bed for the head works, short of the rocky gorge from which the river emerges into the plains.- Below this point the course of the river is so liable; to shift to, any point between the terraces which are wide apart, and the height to which the river rises in times of flood is so great, that in such open material it would be inadvisable to attempt' a supply from any portion of the river below the gorge. The height of the northern terrace ranges from 70 to 250 ft. above the river, bed. About a mile and a .half above, the point marked in blue thus—X—on plan, the river is confined within rocks, and the banks are only about thirty apart. From this,point a supply could be led out by a tunnel about a mile and a half in length, getting on to the level of the plains about four miles from the source, but the expense of the necessary works would certainly not be less than; L 12,000, and except in connection with an irrigation scheme of large magnitude, if even for that purpose, the question of a supply from the Rangitata river should not, I think, bejentertained. Last week, when the springs were as low as ever they have been known to be, I examined various other sources, viz., the “ Limestone Creek,” which yielded only: x,coo gallons per minute, or about a fourth part of the volume which was flowing in it when 1 guaged it in August, *879. This supply might suffice for the line of channel shown by O P Q in red on plan, but could not be expected to do more. The creek which discharges near the forks of the Hinds is of even less capacity, and these two creeks together would not in a time of drought form a reliable supply for the large extent of district proposed to be watered. It seems to me that the proper source of supply for this district is from the South Ashburton river, at a point known as the Sandstone Rock, and marked A on plan. From this an ample supply could be led into the North Branch of the Hinds by a cut of only two miles in length, the lower end of which would pass near the base of tire two rocky hillocks known as "The Brothers.” From B to the Forks of the Hinds at K the river bed would, I think, suffice as a carrying medium, as that portion is not nearly so porous as .it is below the forks. With an aqueduct over the south branch of the Hinds near K, the water might be led in two Separate channels, the one K L M N passing .through the settled, but inefficieiuly watered district, about a mile out Iron} the river, downwards to the township of Hinds, and thence in the direction of road leading towards Coldstream, as far as the junction of roads marked Non plan. The other line L Q R would pass through the cenr
tral portion of the plan, and terminate near Ealing, or it might, at a small extra , cost, be placed nearer the Rangitata river if that should prove more advantageous. The expense of this Hinds-Rangitata scheme (including half cost of head works at A, cost of aqueduct over Hinds, also earthwork, bridges, and culverts, tanks, floodgates, &c.) I estimate at L 3,700 5 or, exclusive of the line .0 P Q from Limestone creek, L 3,000. The total length of water races would be fifty miles. It is possible that the charging of the' Hinds in the dry season with water from the source proposed would yield a supply sufficient'to fill the wells for a good way down the Hinds, and if such prove to he the case, the formation of the races might well be postponed for a time ; but even if it were found that the portion of the North Hinds above the forks was too porous for carrying an adequate supply, the enlarging of the channel which I should now propose to be cut on line H C D E G would ensure a supply at the forks near K, from which it nvght be led into the race as proposed. The cost of enlarging ■ said channel over the length of 15 miles might, be set down at about L3OO.
7. Hinds-Ashburton Water Supply.—Having recommended the South Ashburton river near the Sandstone Rock as the source of supply for tile Hinds-Rangitata district, I am of opinion that the Hinds-Ashburton scheme should now also start from this point, as the cost for head works would be less there than at (he point F on plan, and the cost of the head works being equally divisible betwen the two schemes, the cost; of the Hinds-Ashburton scheme in this way would be as nearly as possible in accordance with the previous estimate, 1,1,650, prom the representations of owners I find that , a greater detour than shown «n plan will he necessary in some places in order that a larger number 9! owners may be huts the aggregate extra cost will not be much, I
would suggest that the lines be staked out,; before the works are tendered for, so that there' may be an opportunity given of making any slight deviations which may seem necessary in order to give the possible service. 8. Water -Supply, Mount Somers. —I have gauged the supply from proposed source at Deep creek, and find it yields a minimum of 4,000 gallons per minute, which would be quite equal to the requirements over the proposed length of li miles of channel. The intake would be situated about 12 chains above the point where the public road crosses the creek. The owners interested in thi; scheme are to have a meeting to consider the question of maintenance, as well as some points connected with the route, and will 1- form you ,of their decision before next meeting of the Council.
9. Wheatstone Drainage.—The work at Taylor’s creek which the Council authorised has now been executed- . This should have the effect of preventing the diversion of the creek, but will not ensure a Supply in times of drought to the settlers situated near the. lower end of , Flood channel, unless the supply from Ford’s creek, initiated by the, Longbeach Road Hoard, is kept up, or otherwise an equivalent or larger supply introduced from the Ashburton river. : 10. Salcyards.—l beg to submit plan showing proposed extent of/plantation in connection with the yards. The area is 8 acres, length of ncw fencing required Chains, besides the filling up of gaps in present gorse fences. The season being Suitable now-, the ploughing for plantation might be proceeded with, if the Council approve of the proposed site, and extent shown for planting purposes, t—l have, &c., , William Baxter. lie the portion thereof dealing with the Rakaia plains Water Supply,/the report of the Committee haying been read, it was resolved—" That the report of the Committee on the Rakaia and Ashburton plains Water, Supply be adopted, with a proviso that channel B ; shall not be proceeded with until the landowners to be benefited thereby shall place themselves upon the siine footing as regards the cost of construe)ion, maintenance, and repairs, as applies to the landowners within the rating area ” . It was also decided that the line asked for by Messrs Mackie and others be considered as , pne of the lines to receive early attention, should the quantity of water prove sufficient for watering additional’area, and that it;be. marked in red on the map, as soon as the landowners have complied with the resolution- of the Council as to rating ; and that the lines near, to Drqraore and Chertsey be proceeded With. Consideration of the report on the Hinds-Raugltata Water Supply, and*.on the Hinds-Ashburton Water Supply was deferred to special meeting. That portion of the report dealing with Wheatstone drainage ahd aaleyards was approved.; INSPECTOR OP SLAtmHTEBHOUSES REPORT. 1 his was read and approved. HOSPITAL IMPROVEMENTS.
Messrs Fooks and Son submitted suggestions re (jettain. improvements to the hospital, afid tKe same Were left in the hands to act upon.. HAILWAY MANAGEMENT. The notice of. motion standing in Mr Walker’s name was further adjourned. EXHIBITION grant. The Chairman filled in the blank remaining in his; notice of motion for a grant to the Committee of: the Industrial Exhibition,making the sum L 250.
Mr Wright seconded this. Some discussion ensued, in which Mm Grigg spoke deprecatingly of the whole affair,, (referring to the show as one of toys, and not likely to be of any good to the place, and Mr Coster expressed .it as his opinion that: the grant was too large, -p I , Following this the motion was put and lost —Messrs Grigg, Coster, Jackson, and Sauridersi votingoadversely.
