2024 Water Allocation

After careful consideration of the current water supply of the Oldman and Keho Reservoirs, forecasted watershed yield from remaining mountain runoff and annual crop demands, the Board of Directors of the LNID passed a resolution at their June 25, 2024, meeting to increase the allocation of water from 8” per irrigation acre to 11” per irrigation acre. This corresponds to a change from 45% of full allocation to 63% of full allocation. Although LNID irrigators will continue to be restricted, this increase will make a significant difference in the management of on-farm operations and help mitigate the effects of the ongoing drought. We have seen significant gains following our June 11th Board review as a result of timely rains, cool temperatures, and relatively low demand during early crop growth. On June 11th, an allocation of 8” per irrigation acre was recommended based on the available stored volume and no projected watershed yield. Good collaboration between LNID operations personnel and the Water Infrastructure and Operations Branch of Alberta Agriculture and Irrigation helped capture additional runoff and effectively respond to water demands during recent rain events. The resulting gains are being shared between the 2024 growing season and enhanced reservoir storage for 2025. The decision to increase the allocation now is intended to advise irrigators as early as possible so they can make best agronomic use of the available shared water to mitigate the effects of the current drought on their operations. This approach is consistent with the considerations and principles of the 2024 Water Sharing MOU for the Oldman South Saskatchewan River Basin, of which LNID is a signatory.

The Water Supply Outlook, water use, and forecasted demands are being tracked in detail. The rationale for the 11” allocation is as follows:

The Oldman Reservoir is at 91% of full supply volume and Keho Reservoir is at 96% of full supply volume. Assuming full use of the 11” allocation, including that already used in LNID this year, adding a low projected watershed yield (inflow to Oldman Reservoir) similar to 2023 to the current reservoir storage volume, and meeting projected downstream flow requirements for other system demands in our basin, this would result in an end-of-season Oldman Reservoir volume of nearly 43%, on track to be significantly ahead of the 28% seen at the end of 2023.

LNID thanks all irrigators for their continued cooperation in managing restricted allocations, and all those working hard to make every drop count within the Oldman South Saskatchewan River Basin.

2024 Weed Control Treatments

The Lethbridge Northern Irrigation District will be controlling broadleaf weeds along its right-of-ways for the 2024 irrigation season. The chemicals used will be Dycleer, 2,4-D Amine 600 and Amine 500 herbicides. Round-up will also be used for weed control on graveled driving banks and for reed canary grass control. This Spray program will be starting in May of 2024 and will continue to the end of the irrigation season.

Also included in this weed control program will be the treatments for aquatic weeds. To control these aquatic weeds, the Lethbridge Northern Irrigation District may be treating the Canals noted below on the approximate dates shown during the 2024 irrigation season. The Canals will be treated with Magnicide H (Acrolein, Inhibited) to control the growth of aquatic weeds and algae.

Projected 2024 Aquatic Treatment Locations & Dates:








MAY 13, 20, 27 JUNE 3, 10, 17, 24 JULY 1, 8, 15, 22, 29 AUG. 5, 12, 19, 26 SEPT. 2, 9, 16, 23, 30

All sub laterals that take water from the above noted laterals may/will be affected by these treatments. Please read the supplied material if you have land by these treatments or receive water from these canals.

This weed control program is administered by licensed applicators under the approval from Alberta Environment & Protected Areas. Go to www.lnid.ca to view a detailed map of the above referenced areas and updated information.

No Hunting on District Property

The district administration would like to remind all residents and visitors that hunting of any kind is strictly prohibited on district land. This prohibition is in place to ensure the safety of all individuals on district land, as well as to protect the natural habitat and wildlife within the area.

The prohibition on hunting includes, but is not limited to, the use of firearms, bows and arrows, traps, and any other devices used to capture or kill animals. This prohibition applies to all individuals, regardless of whether they are residents of the district or not.

Any individuals found to be hunting on district land will be asked to leave the area immediately and may be subject to legal action. The district administration takes this matter very seriously and will take all necessary measures to enforce this prohibition.

We appreciate your cooperation in helping to maintain a safe and enjoyable environment for all on district land. If you have any questions or concerns, please do not hesitate to contact the district administration. Thank you for your understanding and compliance.


  • LNID Board Meets with Agriculture Minister RJ Sigurdson

    June 12, 2024

    The LNID board of directors met with Agriculture Minister RJ Sigurdson in Calgary on May 2, 2024. Five topics were discussed:

    1. Drought in 2023 caused damages to some crops in LNID. The LNID Board advocated for compensation for these extraordinary losses. LNID irrigators experienced significant 30-40% losses in winter crops such as winter wheat, alfalfa and grass that were not fully covered by insurance. The board heard that the rationale for not sending compensation for crop losses was that for those who had insurance through Agriculture Financial Services Corporation (AFSC), there were only a few claims triggered in the LNID region. Although the Board was hoping for a different outcome, we are confident that the consideration of this issue received the time and attention that it deserved.

  • Golf Course Operators in LNID

    June 11, 2024

    Alberta remains in Stage 4 (out of 5) of its water shortage management response plan and LNID Irrigators are currently facing a 50% reduction in their allocation. This is water to grow our food. The LNID recognizes that Golf Courses rely on healthy greens and fairways to sustain a viable business. We are asking Golf Courses with LNID Water Agreements to aim for a target reduction of 15-20% in prioritizing your water use.

    Every drop matters in the effort to conserve water across Southern Alberta. This suggested reduction for Golf Course water use is intended to match those encouraged by other irrigation districts in the area.

  • LNID Domestic Agreement and Household Purposes Agreement Users

    June 11, 2024

    Alberta remains in Stage 4 (out of 5) of its water shortage management response plan and LNID Irrigators are currently facing a 50% reduction in their allocation. This water is used to grow our food. The LNID is asking Domestic Agreement users and Household Purposes Agreement users to take action in decreasing your water usage. Recognizing that the establishment and long-term health of lawns, trees and shrubs needs to be considered, these efforts could include:

    • Limiting outdoor water usage, including watering lawns or washing vehicles, to essential needs
