The storm drains most certainly could be the reason for your lack of clarity and of course the sediments coming in could fertilize your phytoplankton giving you the green water. The green water is uptaking your nutrients and blocking out sunlight so you don't get any macrophytes. Actually that's what fish farmers and many pond onwners strive for but it can be tricky to achieve.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
