If you smelled something that smelled like rotten eggs (hydrogen Sulfide) then the lake's turning over in that area.

All it takes is a few cold nights to equalize the water temperatures at the surface with the hypolimnion water temp and the water will start mixing vertically. High winds can increase and encourage the mixing. Winds create currents and the currents help break up the thermal stratification.

And you were down by the Dam. There is probably more current in that area as the water is going through the dam there. Although that the deeper part of the lake and it takes more heat loss to drop the water temp down to where it will turn over. It's been pretty cold the last week or two.
