Eastern Irrigation District

The following is a complete list of all projects included in the Eastern Irrigation District (EID) under the modernization program. There are 28 pipeline projects, four canal rehabilitation projects, and one reservoir expansion project.

Current Modernization Projects (2022/23)

Secondary C North Branch

This project is located at the SE end of Crawling Valley Reservoir and is designed to keep spill in the reservoir. Serving a third of the acres off the North Branch Canal, the proposed 6.4 km gravity pipeline will pick up existing deliveries off this section of the canal, tie into the present Secondary C North Branch pipeline, and be sized for over 1,150 additional acres for future corner arms and pivots. Twin 60″ pipe will be installed for the first 4.6 km, to a single 60″, and then 36″ line, to supply 8,695 acres.
Although it is necessary for the existing canal to stay in place, this rehab will eliminate 2 check structures and a rock weir in the North Branch Canal. 

The estimated cost of the project is $15,890,000.

Lake Newell South Feeder

This project is located 6 km NE of Rainier, beginning at the Bow Slope Canal, extending to the SW corner of Lake Newell Reservoir. The rehabilitation includes trimming, armouring, and fencing 3.2 km of the existing canal and increasing the capacity from 550 cfs (cubic feet per second) to 800 cfs to allow more flow into Lake Newell Reservoir.

The estimated cost of the project is $1,826,000.

Reservoir Projects

Snake Lake

The proposed Snake Lake Reservoir expansion plan will increase the reservoir live storage by approximately 53,000 acre-feet to 67,000 acre-feet*. 

Currently, 140,000 irrigated acres are either unsupported by a reservoir or receive limited reservoir support. Approximately 50,000 of these acres are downstream of the Snake Lake Reservoir.  The Snake Lake Reservoir expansion will reduce the unsupported acres in the District by 35 per cent. 

The remaining 90,000 acres will continue to be unsupported by a reservoir but will see increased indirect support due to the increase in acres supported by the Snake Lake Reservoir Expansion. 

Environmental and engineering investigations are underway, meetings with affected landowners are ongoing, and discussions with government officials on the regulatory approval process are occurring. 

* An acre-foot covers one acre of land, one foot deep.

Completed Modernization Projects

C Springhill

This rehabilitation project is located approximately seven kilometres north of Brooks. The proposed rehabilitation is to install a closed gravity pipeline system that starts at Rock Lake Reservoir and continues east across the Duchess highway. At Rock Lake Reservoir, there will be a shared stilling pond and gabion wall with the 01-C Springhill system. The system will tie into a few existing pipelines, one being the Long Pump. The pumps on this system will still be necessary for priming pressure to the landowners. The start of the pipeline is 60” pipe, and the new system will supply 6224 acres, 97 per cent of which are sprinkler and will be 10 kilometres in length. The major benefit of the project is the maintenance of spill water within Rock Lake Reservoir.

The final cost of the project was $12,200,000.

01C Springhill

The 01C Springhill project will replace the 30-year-old Springhill pump station with a new pump station located at Rock Lake Reservoir, providing the opportunity to capture all spill water. This new pump station will supply 1757 acres with full operating pressure, negating the need for irrigators to operate their own pumping systems. The starting pipe size will be 30” and the pipeline will be six kilometres long. 

The final cost of the project was $5,200,000.

9H West Bantry

The 9H West Bantry pipeline project will finish converting the 9H West Bantry system into a closed pipeline. The project is located approximately 2.4 kilometres north of the intersection of HWYs 875 and 535. The new pipeline will be 1.8 kilometres long and currently serves 541 acres. Fifty-three acres will be added to the pipeline to eliminate a delivery in the H West Bantry canal, which currently accepts spill water from flood water in NE8 17-13W4M.  As such, only the first half mile of the ditch can be pushed in, with the remainder maintained as drainage works. 

The final cost of the project was $1,100,000.

10H West Bantry

The 10H West Bantry pipeline project will convert the 10H West Bantry system into a closed pipeline.  The primary benefit of this project will be a reduction in spill. The project is located at the intersection of HWYs 875 and 535. The new pipeline will be 5.5 kilometres long and serve 1117 acres. The pipeline will require two road bores under paved highways and include a screen cleaner at the inlet structure.

The final cost of the project was $3,100,000.

16H West Bantry

The 16H West Bantry pipeline project will convert the 16H West Bantry system into a closed pipeline.  The primary benefit of this project will be a reduction in spill. The project is located 3.2 kilometres south of the intersection of HWY’s 875 and 535. The new pipeline will be 3.3 kilometres long and will serve 1112 acres. The new pipeline will require one bore under highway 875 and will include a screen cleaner on the inlet structure. 

The final cost of the project was $2,000,000.

 

08B Springhill Extension

08B Springhill pipeline extension will serve 429 acres through a pipeline length of three kilometres. This closed gravity pipeline will meet the delivery points of three existing pivots that currently pump out of a drain that sees a reduced amount of water every year. This new pipeline will move them from that drain and onto a closed gravity system. 

The final cost of the project was $806,000.

12 Springhill

The 12 Springhill pipeline involves replacing the remainder of the open channel ditch with a closed gravity pipeline completing the system. This pipeline will serve 5118 acres with a starting pipe size of 54”.  The start of the pipeline will be relocated upstream of an existing reservoir, providing the opportunity to capture spill water. 

The final cost of the project was $3,600,000.
