Gull Lake Water Level






Gull Lake, located in central Alberta, Canada, approximately 30 kilometers north of Red Deer, has been experiencing significant challenges with water levels, impacting recreation, tourism, wildlife, and local investment. Below is a detailed overview of the current situation, historical context, and ongoing efforts to address the issue.

As of the most recent data from Parks Canada, Gull Lake's water level was recorded at 2.165 meters on April 29, 2025, slightly below the average of 2.13 meters for that date, with historical minimum and maximum levels ranging from 1.81 to 2.75 meters1. Earlier in the year, on March 20, 2025, the level was lower at 2.006 meters, compared to an average of 1.69 meters for that date8. As of August 2024, the Government of Alberta reported that levels were about 57 centimeters below average and 78 centimeters below the full supply target elevation of 899.16 meters3. These low levels are among the lowest in decades, comparable to periods in 1976-1980 and 2002-200636.

Gull Lake's water levels have fluctuated by about one meter since the early 1960s, a pattern consistent with other central Alberta lakes3. Between the early 1920s and mid-1970s, levels declined by an average of five centimeters per year, prompting the provincial government to implement a stabilization system in 19766. Operated by Alberta Agriculture and Irrigation, this system pumps water from the nearby Blindman River into Gull Lake to maintain levels for recreational and habitat purposes3. Over 47 years, the project has pumped approximately 122 million cubic meters of water into the lake during 23 years of operation, averaging around five million cubic meters annually when active3.

Pumping triggers are based on specific lake elevations: pumps activate when levels drop to 898.93 meters and stop at the target elevation of 899.16 meters to mimic natural fluctuations3. However, pumping was suspended in 2018 after the invasive Prussian carp was detected in the Blindman River, halting operations to prevent the species from entering Gull Lake367. Since then, levels have continued to decline, exacerbated by drought conditions and insufficient river flow, with the lake losing an estimated five million cubic meters of water annually56.

The declining water levels have had significant repercussions. Marinas and docks have become virtually unusable, and some boat launches and beaches, including a main provincial park beach, are nearly dry26. This has disrupted recreational activities and tourism, which are major drivers of local investment, with over 2,961 properties and an assessed value of about $1 billion around the lake23. Additionally, low levels threaten aquatic habitats, particularly for spring spawning sportfish like northern pike, walleye, and yellow perch, which rely on shallower areas3.

Several initiatives are underway to address the situation:

  • : The Gull Lake Watershed Society, in collaboration with the Alberta government, has proposed a pressurized filtration system to resume pumping from the Blindman River while preventing Prussian carp and their eggs from entering the lake267. The estimated cost for the filter system and a 1.2-kilometer pipeline is around $600,000, with the society aiming to raise half and seeking government funding for the remainder26. Public consultation occurred in August 2024 through open houses and an online survey, with feedback under review as of September 20247. If approved under the Water Act, pumping could resume in spring 2026, though it may take five years to reach target levels, depending on river flows26. Current low snowpack and drought conditions pose challenges to river flow availability6.

  • : The Gull Lake Watershed Society is also seeking a $200,000 Alberta Community Partnership grant to fund a feasibility study on reopening two historical channels at the lake's north end, which once supplied water but were filled in by silt and vegetation after logging and road construction over a century ago5. The study aims to assess restoring inflow and installing flood control measures, with applications pending as of August 20245.

Pumping from the Blindman River is constrained by low-flow periods, especially in summer and fall, with a minimum flow requirement of 0.4 cubic meters per second to operate even one pump, and a regulatory minimum of 0.14 cubic meters per second downstream3. Recent water shortage advisories and drought conditions have further limited potential pumping36. While historical stabilization efforts have helped, natural fluctuations due to precipitation and evaporation remain unavoidable3.

The Alberta government and local stakeholders are committed to addressing these challenges through public engagement and innovative solutions like the filtration system. However, the timeline for restoration depends on regulatory approvals, funding, and environmental conditions.
