It says that it is currently 7.0 feet below the minimum healthy water level and that the healthy water level is 4198 feet.

I bet that will confuse a lot of people who will think that means the lake should be at least 4198 feet deep and it is 7 feet below that. Being 0.17% low doesn't seem like a major problem.

Apparently though lake levels are measured relative to sea level, and Utah is around 4200 feet above sea level.

The Great Salt Lake is only about 15 feet deep when at its normal level, so 7 feet below minimum safe level is quite low.

Worse: The topography there is really flat. Every foot of lake elevation is a massive change in the surface area of the lake. I don't know the exact numbers, but it would not surprise me if there were a mile of change in lakeshore location for a foot of change of lake elevation.
