Brno, [Date] – The Brno Reservoir in the Czech Republic, known for its recurring algae problem that made the water unsafe for swimming during summers, has experienced a remarkable improvement in water quality. Recent measures have significantly reduced the amount of algae in the reservoir, allowing visitors to enjoy swimming without any concerns.

In the past, the Brno Reservoir would often turn into a thick, green sludge due to excessive algae growth, typically occurring as early as mid-July, effectively ending the swimming season. However, recent years have seen a drastic change, and this year’s water quality is being hailed as excellent.

The successful implementation of measures to improve water quality has been confirmed by hygienists and employees of Povodí Moravy. Despite the recent heat wave and minimal water flow in the reservoir, the water quality has been rated as a commendable 2 out of 5 by the Regional Hygiene Station.

The reduction of phosphorus levels in the reservoir has been particularly effective in curbing algae growth. By limiting the amount of phosphorus entering the reservoir, the conditions for algae proliferation have been minimized. The installation of unique air diffusion towers has further aided in mixing and aerating the water, creating an environment that is less conducive to algae growth.

These measures were introduced in May this year and have consistently maintained water quality. Most dissolved phosphorus is now captured and prevented from entering the reservoir, significantly reducing the nutrients available for algae. Despite high temperatures and low water flow, algae growth has been substantially limited. Any minor fluctuations in water quality have been attributed to natural causes, such as stormwater runoff and the development of phytoplankton.

Overall, the implemented measures to enhance water quality have proved successful, and the Brno Reservoir now offers excellent water conditions for swimming. Visitors can enjoy their summer swims without any issues, and the situation is expected to remain stable throughout the season.

Continuing efforts to improve water quality will involve replacing the existing air diffusion towers with new mixing towers. These advancements are anticipated to further reduce the algae content in the reservoir.

The successful management of the algae issue at Brno Reservoir serves as a valuable example for other areas grappling with similar problems in their bodies of water. With diligent attention and consistent efforts, water quality in such regions can be significantly enhanced, ensuring safer and more enjoyable swimming experiences for residents and tourists alike.
