What Makes a Lake Clear?
Before we dive into the clearest lakes in Montana, let's discuss what makes a lake clear. Water clarity is primarily determined by the amount of suspended particles, such as algae, sediment, and dissolved organic matter. Other factors include water temperature, sunlight, and the lake's depth. Shallower lakes tend to have clearer water, as sunlight can penetrate deeper, promoting the growth of aquatic plants that help filter out suspended particles.
