    Default Bubbles in the water

    In fishing some lakes near DFW the last few months I noticed on livescope a lot of scattered bubbles streaming up from the bottom of the lakes. These were in areas of flooded timber where I mostly fish. This situation has occurred both prior to turnover and now in turnover. In some places the stream of bubbles is so thick I can't easily make out the fish and move on. Does anyone know what these bubbles typically are (air, CO2, methane, other)? If air, I would imagine that the extra oxygen might be a plus and perhaps actually attract crappies and their quarry. If CO2 or methane (from leaking of subsurface hydrocarbon deposits or decay of bottom vegetation), I would imagine the opposite situation. I saw and caught some fish in the areas near significant bubble streams so I'm not sure what to think. Anybody have experience with this or knows the science behind it?

    Bubbles are probably from sulfurous gas from decomposing materials on the bottom that get riled up from the turnover process.
    I have spent most my life fishing........the rest I wasted.

    That’s what I have been told as well. Unless it is extremely heavy I wouldn’t worry about it. Seems there is always some around where I fish and i haven’t yet noticed the fish mind

    I have seen places that looked like it had a areator running down on the bottom

    There are apparently multiple sources for the gas bubbles. Some are even contributed by the fish themselves. Check out this article:
    Fish bubbles – what to look for and what they really mean | Advnture

    As the article says, agitation of the water column can cause greater release of the lake bottom bubbles. I imagine that an outboard motor or even a trolling motor on spot lock can cause enough vibrations to agitate the lake bottoms. It would be interesting to see if the bubbles are reduced if one ties the boat off to a submerged tree or anchors with a raptor of conventional anchor instead of continuously running the trolling motor at a fishing spot.

    I have bumped into old standing timber causing bubble to come up.

    I would think decomposition of organic matter on the bottom is in the mix ,made a few come off a condo I set out moths ago yesterday myself .
    Beyond that , this much is often factual , those bubble streams will give up cover on the bottom more often than not ,a friend to a bank person going at it all blind and helpless like me for sure

    I would think leaves laying on the bottom decomposing would be a source of bubbles. In vlear water you can see them stream from the mud itself
