Sep 18, 2015 · Lake Ontario. The increases in Lake Ontario water clarity suggested by the lake-wide mean Z SD in Fig. 3B and Table 1 are confirmed by the annual Z SD anomalies to be a lake-wide phenomenon (Fig. 8). Lake Ontario Z SD varied from consistently 3–4 m below the long term mean in the 1970s and 1980s, to broadly above average since the 1990s. It ...

clarity over the Great Lakes. Lakes Ontario, Huron, and Michigan have seen increases in average Z SD over the three sensor periods of 58%, 49%, and 62%, respectively. Lake Erie shows highly variable Z SD with no consist-ent long term trends, while Lake Superior has remained fairly consistent in its lake-wide water clarity condi-tions.

What is happening in Lake Ontario ZSD?
Lake Ontario is similar to Lake Erie in length and breadth (193 miles by 53 miles). Yet with its greater average depth (approximately 283 feet), Lake Ontario holds almost four times the volume (395 cubic miles) and has a retention time of about 6 years. The drainage basin covers parts of Ontario and New York, and a small portion of Pennsylvania.
