Climate change can make harmful algal blooms worse in lakes. By adjusting nutrient levels, we can help prevent this. Current nutrient criteria may need to be stricter to keep lakes healthy. Warmer temperatures from climate change mean we need less nitrogen and phosphorus in the water. If we don't reduce nutrients, more lakes could have algal blooms in the future. To protect lakes, we should lower phosphorus levels especially. It's important to update nutrient guidelines regularly to keep water safe from harmful blooms caused by climate change.
