2020 Lake Zumbro Dam Fall Drawdown

Friday, October 30th, 2020

The fall drawdown of Lake Zumbro is scheduled to begin on November 1st. The drawdown is necessary for planned maintenance and shoreline restoration work.  The public should be aware that the drawdown planned for this fall will be substantially greater than normal.  A typical fall drawdown is less than two feet; whereas this year a four foot drawdown will be attempted.  These plans are subject to change depending on rainfall and resulting runoff.  RPU’s drawdown plan is as follows:

  • Sunday, November 1st start the 4 foot drawdown.
    • RPU will plan to draw the lake level down 0.5 feet per day while maintaining a minimum flow of 70 cfs.
  • Monday, November 9th the lake level will be held at 910.5 MSL (4.0 feet below the spillway) for 2 weeks.
  • Monday, November 23rd start to refill the lake level until it reaches the winter pool elevation of 913.0 MSL.

The drawdown plan is subject to change depending on weather conditions.

During the months of November through March, Rochester Public Utilities (RPU) will attempt to maintain the lake level at the winter pool of 913.0 MSL.

Real-time lake level information, along with Lake Zumbro hydro updates are available on the RPU web site ( For additional information regarding the Zumbro Hydroelectric Facility please contact Tony Benson at (507) 280-1534.

Tips for lake ice safety:

Be extremely careful during winter activities that involve Lake Zumbro such as ice fishing, snowmobiling or just walking out on the frozen lake.

Watch the weather and river flow conditions.

Ice thickness and condition can vary greatly. Be very cautious.

Look out for ice heaves and exposed logs and snags.

Be cautious in the vicinity of the dam. De-icing equipment has been installed along the upstream face of the dam resulting in open water and/or thin ice.

Do not proceed past the warning signs and buoys.

Sustainable Water Utility Management Award Winners

Anaheim Public Utilities (APU) continues to achieve financial effectiveness by maintaining robust liquidity, minimizing long-term obligation, offering affordable and competitive rates in the face of COVID-19 pandemic challenges and rising water supply costs. APU employs data analytics to optimize decision-making, organizational performance, and capital project investments. The utility invested over $67 million in capital improvement projects to support long-term water system sustainability. APU consistently focuses on assisting customers and partnering with them to help the community prosper. Through rebate and incentive programs, Anaheim also achieved a 30 percent per capita water use reduction in 2020.

Charleston Water System (CWS) established capital planning programs that ensure water and wastewater capacity, fire protection, and environmental and regulatory compliance requirements are fully met. It is the first combined utility in the U.S. registered in conformance with the Environmental Management System standards of ISO 14001. A dedicated source water manager maintains source water infrastructure, works with watershed stakeholders to address water quality and quantity concerns, and develops a source water protection plan. The CWS  low-income assistance initiative supports customers in need through the Palmetto Community Action Partnership, and creation of a Citizens Academy program enhances customer education and engagement.

Contra Costa Water District (CCWD) is a state-wide leader in water affairs with a focus on preserving Delta water quality and developing regional water supply reliability. CCWD is committed to balancing operational expenditures, revenues, and debt service while investing in infrastructure assets; controlling operations and maintenance expenditures, while increasing water quality and customer service levels.  The utility incorporates climate change considerations and resiliency into long-term planning, addressing vulnerabilities and investing in improvements that will increase sustainability. It has made significant investments in water use efficiency projects that have reduced total water use by over 30 percent since the late 1980s.

The El Paso Water (EPWater) strategic plan objectives include strengthening financial viability, improving land and water management, increasing innovative solutions, and strengthening stakeholder partnerships. Its financial management is consistently recognized for its bond ratings, debt service, audits, budgets, and pricing structures. EPWater has developed aquifer storage and recovery, advanced water purification desalination, and water importation projects, which contribute to a diversified water portfolio. Investments in flood control, water conservation, and open space preservation make EPWater a leader in environmental stewardship. The utility engages the community through payment assistance programs to help low-income seniors and low-income families financially impacted by COVID-19.

Greenville Water had the foresight to purchase watersheds in a high rainfall area, construct dams to develop reservoirs at favorable hydraulic gradients, and limit the access to its watersheds, ensuring a sustainable water supply for the next 100 years. The utility maintains a AAA financial rating from all three major rating agencies and a financial plan that supports daily operational needs and meets required debt services. Its asset management program promotes the continuous improvement of business processes, and its business services model optimizes employee efficiencies to benefit customers and billing partners. A robust watershed management plan supports resource management through strategic planning and partnership efforts.

KC Water implements sustainable management using green infrastructure solutions whenever possible as part of a 25-year, $5 billion program to mitigate adverse effects of its combined sewer system. The utility’s aggressive asset management program minimizes the cost and maximizes the benefit of infrastructure investments. KC Water relies on climate studies and other research to drive planning and execution of short-term operations and maintenance and long-term capital improvement programs, serving both immediate needs and generational impact. These initiatives have also saved treatment costs, delayed or avoided additional water and wastewater treatment expansion, and minimized risks to the water supply.

New York City Department of Environmental Protection (DEP) achieved progress in a broad range of sustainability-related factors, including: receiving a 10-year filtration avoidance determination for drinking water from the EPA in 2017, building the largest green infrastructure program in the country with over 10,000 assets spread across the city, achieving Envision and LEED certifications for multiple projects, and launching innovative and impactful rate payer assistance programs. DEP approaches these achievements with triple bottom line thinking that assesses and seeks to maximize the utility’s priorities of protecting health and the environment, supporting its constituents and communities, and benefitting the economy. 

Peace River Manasota Regional Water Supply Authority created a reliable, sustainable, and affordable water supply in southwest Florida and provides the infrastructure for business development and economic growth. Through partnerships the Authority invested in alternative water supply (AWS) and interconnecting the major water supply systems. The utility is a model in AWS development, implementing surface water storage by off-stream reservoirs and aquifer storage and recovery systems. Limiting water withdrawal to occur only during high flow periods provides the sustainability of the downstream estuary and Charlotte Harbor while meeting demands for public water supply.

South Central Connecticut Regional Water Authority (RWA) is focused on the long-term economic viability of its company, resources, and region. Periodic studies ensure its rates reflect the true cost of water and remain affordable. Internally generated funds finance the capital program and increase discretionary reserves.
