Why does the salt remain?
Great Salt Lake has no surface outlet to the ocean. Rivers carry dissolved minerals into it; as water evaporates, salts remain. The lake is a remnant of ancient Lake Bonneville, but its salinity, water level and shoreline continue to change with environmental conditions.
High salinity does not mean an absence of life. Brine shrimp, brine flies, and surrounding wetlands sustain many migrating and resident birds. Small lake organisms also connect this inland water with aquaculture farther afield.
When water levels decrease, salinity and exposed lakebed area change, affecting the ecosystem and surrounding life. Lake protection requires an understanding of inflow volumes, agricultural and urban water usage, wetlands, and habitats, not just looking at a pretty aerial photo.
