In recent years, thick green mats of algae—called filamentous algal blooms (FABs)—have started appearing more often in mountain lakes like Loch Vale in Rocky Mountain National Park. These blooms are different from the usual algae that float in the water because they grow along the lake bottom. Even though scientists have been studying Loch Vale for decades, these types of blooms have only become common in the last ten years. This project looks at whether certain nutrients, especially nitrogen and phosphorus, are linked to these blooms. I collect water from areas with and without blooms, test the samples in a lab for nutrient levels and organic material, and use computer tools to compare the results. By learning what causes these blooms, we can better understand how climate change affects mountain lakes and help create better plans to protect them in the future.
