SAN DIEGO (NEWS 8) - There is something lurking in the water of Lake Jennings.
It's not a sea monster, but rather a tiny submarine that is part of a study testing the lake's water quality.
On October 30th, a harmless dye called rota-meen was put into Lake Jennings by Scripps to track the mixing of purified water with the water of the lake.
Now more than ever, San Diego needs a study supply of water. They will collect the data with a submersible drone.
Using advanced purified water could mean less water would need to be imported from the Colorado River.
News 8's Shawn Styles was able to get a close-up look and reports from Lake Jennings with more information.
