Stinking green slime overwhelms picturesque boating lake as businesses lose out on thousands and swans are stopped in their tracks

A picturesque boating lake in Poole Park, Dorset, has been engulfed in thick green algae, prompting complaints from local businesses and environmental concerns. The 50-acre lake, known for its scenic beauty, is now largely covered in a dense layer of green slime, which has led to a noticeable decline in visitor numbers and revenue for nearby establishments. The issue stems from ongoing repairs to the lake’s sluice channel and an extended period of unusually hot weather, both of which have contributed to rapid algal growth. The algal bloom, primarily composed of cyanobacteria, commonly referred to as blue-green algae, has raised alarms among locals and officials alike. These microorganisms can release harmful toxins that pose risks to wildlife, domestic animals, and humans. Contact with the algae can lead to skin irritation, while ingestion may cause illness. The Environment Agency (EA) has noted that such blooms often result in murky water, turning it blue-green or greenish-brown. In addition, the EA has issued warnings about similar outbreaks elsewhere, including in London’s Ham and Kingston on the Thames, where recreational activities were temporarily halted. Local businesses have felt the impact directly. A restaurant and café located near the lake reported a 65 percent drop in turnover, attributing the decline to the unpleasant odor and appearance of the algae. Nick Davies, the owner, described the situation as “disgusting,” noting that customers are avoiding the area altogether. He criticized the lack of immediate action, stating that draining and refilling the lake could have been a simple solution. Other businesses, such as pedalo operators, have also faced challenges, as the algae has made it difficult to operate their equipment and has forced them to relocate operations to alternative locations. Members of the model boat club have similarly been affected, unable to navigate their miniature vessels through the slick surface. Swans, too, have struggled to move through the thick algae, highlighting the broader ecological implications of the bloom. Environmental groups and local activists have expressed frustration, with Bob Lister, a founding member of the Friends of Poole Park, calling the algae-covered lake a “total disgrace.” His comments reflect a growing sentiment among residents and visitors who value the area’s natural beauty and recreational opportunities. In response, Bournemouth, Christchurch and Poole (BCP) Council has initiated efforts to address the problem. Teams have begun manually removing large patches of algae in certain sections of the lake, aiming to improve conditions for visitors. The council has also resumed flushing the lagoon during favorable tidal conditions, a measure intended to reduce nutrient levels that fuel algal growth. However, critics argue that these measures are insufficient given the scale of the issue. Councilor Andy Hadley acknowledged the community’s concerns, emphasizing the council’s commitment to monitoring the situation and implementing additional actions as necessary. The incident underscores a larger trend affecting water bodies across England. Recent assessments reveal that only 14 percent of the country’s rivers, lakes, and coastal waters meet the criteria for good ecological health. This figure, derived from the Environment Agency’s first comprehensive evaluation in six years under EU water quality regulations, highlights the urgent need for improved management practices. As the council continues its efforts, the fate of Poole Park’s lake remains uncertain, with ongoing monitoring and public engagement likely playing key roles in determining future outcomes.
