It's either one of two things: clay particles or iron. Or it could be both. (Didn't your recently have a rain event too?)
Everyone thinks that iron is always brown/orange but when it's diluted it green/cloudy. Iron does not precipitate right away as it comes out of the ground and the water will be as clear as glass. Howvever once the water gets oxygenated the iron precipitates and the water gets color to it.
The only other possibility is an algae bloom but an algae bloom won't happen this quickly.
My trout pond that gets water 24/7 in the summer is the same exact color as you picture from iron. If I would stop the pump as I do in the fall, the iron will eventually settle and the water will be as clear as a swimming pool.
