Long-term restoration requires long-term commitment, and Long Lake is a great example of what that commitment can achieve.
A recent Washington State Lake Protection Association article highlighting restoration efforts at Long Lake in Thurston County, Washington, showcases the progress made through a science-based, adaptive management approach focused on reducing internal phosphorus loading. Monitoring data indicate major reductions in phosphorus concentrations since restoration efforts began, helping improve water quality and reduce conditions that favor harmful algal blooms.
By combining ongoing monitoring with targeted phosphorus sequestration treatments, local partners have demonstrated that meaningful improvements can be achieved while working within annual management budgets.
The success at Long Lake highlights an important lesson for water resource managers everywhere: Address the phosphorus. Restore the ecosystem.
We are grateful to work alongside Thurston County, Long Lake Lake Management District, AquaTechnex, and the many community members committed to restoring and protecting this valuable resource.
