Are more dead bodies uncovered/discovered during a drought?

In seeing all the pictures of how the drought this summer (in the U.S.) is affecting lakes, streams, etc.–does this help uncover any dead bodies? I have no idea how long a skeleton lasts in a body of water without disintegrating, but I wonder whether any are uncovered in situations like this.

There have been many cases of things found, including bodies, after a drought dries up lakes and rivers; for example, Native American artifacts (including a skull anywhere from several hundred to several thousand years old), and as for (mostly?) complete bodies, according to this article, they can be identifiable after at least three years (depending on environmental factors; I would imagine it would be longer in colder regions).

The linked story reminded me of a similar incident here (Wheaton Illinois) during the drought summer of 1987, when a suburban retention pond dried to the point that an auto was discovered near the surface. The auto turned out to contain the corpse of Carole Pappas, the late wife of Chicago Cubs pitcher Milt Pappas, whose disappearance five years earlier had been a controversial and heavily publicized mystery. It turned out that she had driven her car into the pond, probably under the influence of alcohol or drugs, and nobody had seen or heard.
