kawartha lakes 'turn' end of summer

Recommended Posts

recently heard that late august early sept the lakes turn, particularly rice lake, the water changes color and clarity and the fihsing drips off. is this just rice lake or throughout the area? i know all lakes will do it with a temperature drop just wondering how severe and when in the kawarthas

Not to scientifically speaking, this happens in all lakes that are deep enough to develop a thermocline, during the summer. Come the fall, when the surface water cools to the point that it becomes cooler, thus heavier, than the bottom layer of water, the surface water will sink and the bottom water will rise. This is referred to as the the lake "Turning Over." This mixing leaves the lake the same temperature from top to bottom...therefore the fish can use all of the water, and are harder to find.

The rising bottom water carries some debris into the upper layers and the water becomes somewhat cloudier.

However;

It won't happen at the end of August!

You're looking at the end of September or mid-October

Yep- happens later on- wont stop the fish from hitting though. May put them off for a few days- but I catch right until November 15!

Yep, whoever told you that has no clue.

 

Sometimes turnover isn't until well into Oct. It just depends on the weather/wind/temps we're getting. Fishing might be slow for a few days, but once the fish get comfy, its some of the best fishing of the season.

the person who told you this about Rice is probably talking about the algae bloom in August, and into September... it turns the entire surface of the lake green... like pea soup.

Yeah, we do get algae blooms, but if the weather stays like this it won't happen this year. We need water temps in the 80's to make that happen. Rice was still only 72 yesterday.
