oligotrophic

Oligotrophic describes a body of water, like a lake or pond, that has low levels of nutrients such as nitrogen and phosphorus. Because of this, it typically supports relatively few aquatic plants and algae, resulting in clear water and high oxygen levels. These environments often have pristine, healthy ecosystems, but may have less productivity compared to nutrient-rich waters. Oligotrophic lakes are common in regions with low nutrient runoff and are valued for their clarity and natural beauty.
