(FOX 11) - It's a mystery surrounding the Silver Lake reservoir. Some residents claim the color of the water has been changing lately.
Some residents have posted online comments saying maybe it's a growing number of parasites, others think it may be bird droppings.
We got to the bottom of the growing mystery and called the Department of Water and Power.
The DWP maintains the reservoir.
They say their best guess....is the changes are due to algae.
They constantly test the water - and assured us even if it is algae, it's not enough to be concerned about.
DWP says the reservoir has not stored drinking water since December of 2013 so there is no reason for residents to be concerned.
