Wylie Turnover?

I was reading a news article about Murray turning over in the last day according to the USGS readings. It made me think if Wylie turns over at all?

Thanks,

It does not turn over. Too much flow for the water to stratify. Murray retention time is like 200-300 days, Wylie 20-30 days.

What does "turn over" mean? Ive been wondering that for years now.

Thanks bioguy! I didn't think the upper end would turn over due to flow, but wasn't sure about lower end.

djdsouff....

Lake turnover is the process of a lake's water turning over from top (epilimnion) to bottom (hypolimnion). During the summer, the epilimnion, or surface layer, is the warmest. It is heated by the sun.

Cooling surface temps causes the changeover. Fish that were above the thermocline(line between layers) are brought up to the surface with the water.

Bioguy may explain better but I think it's when the water column on the top gets to the same temp (or lower) as the water on the bottom and the water on bottom comes to the top as the water in the top column pushes down. Oh, you can tell if/when it happens. The water coming to the top brings trash and half-rotten black leaves that were settled on the bottom, it stinks, and is usually a brownish color. The water looks 'dead'. This happens in the shallow ends of the lake mostly.
