Dickson Dam Upgrade Project: Current Status Assessment

The Dickson Dam upgrade project in Alberta is actively progressing with no evidence of being placed on hold. Recent government announcements and news reports from early 2025 confirm the project is moving forward according to schedule, with Phase 1 already completed and Phase 2 currently underway. This significant infrastructure initiative aims to enhance the dam's flood mitigation capabilities while ensuring continued water supply security for communities along the Red Deer River.

Project Background and Purpose

The Dickson Dam is a critical piece of infrastructure located approximately 20 km west of Innisfail and 50 km southwest of Red Deer, Alberta1. Built in 1983-1984, the dam created Gleniffer Lake (also known as Gleniffer Reservoir) by impounding the Red Deer River13. The dam serves multiple essential functions for central Alberta:

The primary purpose of the dam is to provide a reliable year-round water supply for municipalities, industries, and agricultural users downstream3. Prior to the dam's construction, winter flow rates in the Red Deer River could drop to as low as 2 cubic meters per second (cms) at the City of Red Deer, creating potential water shortages3. The dam now ensures a minimum flow of 16 cms during winter months, maintaining consistent water availability and improving water quality throughout the year3.

Beyond water supply management, the dam plays a crucial role in flood control for communities along the Red Deer River watershed. During the major flood events of 2005 and 2013, the Dickson Dam reduced downstream flood volumes by approximately 30%, significantly mitigating potential damages to riverside communities3. This flood protection capability makes the ongoing upgrades particularly important for regional safety and security.

The dam also supports a 15 MW hydroelectric facility that began commercial operations on January 16, 19921 24. Additionally, the Gleniffer Reservoir provides recreational opportunities including swimming, fishing, boating, and wind surfing through the Gleniffer Reservoir Provincial Recreation Area12.

Current Upgrade Project Status

The Dickson Dam Spillway Enhancement Project is a multi-phase initiative designed to increase the dam's capacity to safely manage extreme flood events. Contrary to suggestions that the project might be on hold, all recent information confirms steady progress:

Phase 1: Completed

Phase 1 of the upgrade project was successfully completed in October 2023 at a cost of $10.5 million9. This phase focused on enhancing the service spillway and included:

Raising the walls alongside the service spillway to contain higher water flows9
Enhancing the spillway basin to protect downstream areas from erosion during high-discharge events9
Upgrading the spillway's drainage system to safely manage peak discharges during extreme floods9
Increasing the service spillway capacity from 2,500 to 3,500 cubic meters per second7

The completion of Phase 1 marked a significant milestone in improving the dam's overall capacity to manage floodwaters and protect downstream communities.

Phase 2: Currently Underway

Phase 2 of the project began in 2024 and is currently active, with completion expected in 2025810. This phase focuses on the auxiliary spillway and includes:

Modifying and upgrading the auxiliary spillway structure7 8
Increasing the auxiliary spillway capacity from 2,800 to 4,900 cubic meters per second, representing a 75% capacity increase6 7 8
Implementing dam and dike upgrades to improve overall structural integrity and safety6 8

In April 2024, the provincial government confirmed that Phase 2 was proceeding as planned, with Devin Dreeshen, Innisfail-Sylvan Lake MLA and Minister of Transportation and Economic Corridors, highlighting the project's importance for flood mitigation and water security810.

Recent Government Support and Funding

Far from being placed on hold, the Dickson Dam upgrade project has received additional financial support from the Alberta government. In April 2024, the province announced an additional $50 million over three years for its Water Management Program, which includes the Dickson Dam Spillway Enhancement Project7.

This funding supplements the existing $140 million provincial water management program that was already supporting the project78. The continued and increased financial commitment demonstrates the project's priority status within Alberta's infrastructure development plans.

Rebecca Schulz, Minister of Environmental and Protected Areas, confirmed the government's commitment to the project in April 2024, stating: "These improvements will ensure this critical infrastructure can safely manage extreme flood events for years to come"810.

Significance for Regional Water Management

The ongoing upgrade project is particularly significant given the dam's crucial role in the Red Deer River watershed. The Red Deer River Municipal Users Group has expressed support for the enhancement project, recognizing its importance for downstream communities810.

When complete, the upgraded dam will have a maximum discharge capacity of 6,280 cubic meters per second during major flood events3. This represents a significant improvement over current capacity and exceeds the highest recorded historical flow of 1,930 cubic meters per second from 19153.

The project addresses both flood and drought concerns. During droughts, such as in 2001 when the reservoir reached critically low levels, the dam's enhanced operational capabilities will help maintain downstream water supplies even in challenging conditions3.

Conclusion

Based on all available information, the Dickson Dam upgrade project is not on hold but is instead actively progressing according to schedule. Phase 1 has been successfully completed, Phase 2 is currently underway with expected completion in 2025, and the project continues to receive strong government support including additional funding.

The upgrades will significantly enhance the dam's capacity to manage floodwaters while ensuring reliable water supplies for municipal, industrial, and agricultural users throughout the Red Deer River basin. As climate variability potentially increases the frequency of both flood and drought events, these improvements represent a critical investment in central Alberta's water security infrastructure.
