Ya Lake Erie has the same issue, its actually too clean now and being that the lake is a shallow lake 25-30' in the main lake and 5-10' in the shallows . The sunlight hits the bottom and allows the algae and grasses to grow then it gets a green film from the algae. Lake week end the spray off the boats was green. They introduced Zebra muscles years ago to clean up the lake and they cleaned it up to much.
Zebra mussels were not introduced to clean up Lake Erie, they were introduced from ships ballast water. The algae blooms that have been occuring the last several years are caused by elevated phosphorus levels primarily caused by fertilizers and untreated sewage being dumped in the lake during heavy rains.
Here is a website that shows the current location of the bloom.

Since the zebra mussel has become established in Lake Erie, water clarity has increased from 6 inches to up to three feet in some areas.[6] This improved water clarity allows sunlight to penetrate deeper, enabling growth of macrophyte bacteria.
Because of their high abundance and very high filtering rates in shallow aquatic systems, Zebra mussels remove a significant portion of the primary production. In some shallow experimental lakes in Europe, introduced Zebra mussels have improved water clarity and macrophyte growth, and it has been argued that they can improve the quality of the algal resource base so that food web efficiency and fish production can be increased. As a result, some scientists have advocated introduction into other aquatic systems. Improvement of water clarity has been seen in Lakes Erie and St. Clair; however, in Lake St. Clair, the increased water clarity may have contributed to massive blooms of vascular macrophytes that have washed up on shore and fouled beaches. In the inner portion of Saginaw Bay, water clarity improved in midsummer of 1991 and 1993; but in 1992, 1994, and 1995 there were marked decreases in water clarity owing to massive blooms of Microcystis, a potentially toxic colonial cyanobacterium, or blue-green alga. Blooms of Microcystis also occurred in western Lake Erie in 1995 and 1998. In addition, there have been outbreaks of near-bottom blooms of the filamentous alga Spirogyra, which have later washed up on beaches.

Unless we get some awesome weather in the next few weeks.
Probably won't happen for another year but at least we can start looking.
