Not to be a smart alec, but the St. Johns River is a long river. There are many gauges along the river to monitor the levels.

This website: https://water.weather.gov/ahps2/hydr...rce=hydrograph

will show the levels along the river.

You will have to scroll down to where it shows a map, click on the link for downstream or up stream gauge. If you click to zoom in or out you can see all of the gauges along the river. Click on the dot for the gauge that you are interested in, and you will find current levels and predicted levels.
Hope this answers your question.

Water got too high so they drown....

It fell from the sky, splashed down, etc, etc, etc ....
It seems to me there'd be more than the regular amount of

Danny,
Google up my fwc.com .......how do hurricanes kill fish
did you see the graph of the o2 levels in flycaster's earlier post

OK, this was what I was looking for --->

Low dissolved oxygen
Low dissolved oxygen is by far the most common cause of post-storm fish kills. When oxygen levels get too low, fish are unable to obtain the required amount of oxygen necessary for metabolism. Several factors may occur in concert to cause this condition:

• Wind-In small lakes or ponds, wind action may push surface waters to one side of the lake. Water from the bottom comes to the surface to fill the space the surface water used to occupy, bringing with it sediments and organic materials from the bottom. This water from the bottom is naturally low in oxygen. The bottom materials may include hydrogen sulfide; in high enough concentrations, hydrogen sulfide can be lethal to fish and is responsible for any "rotten egg" or "sewage" odors. Bacteria in the sediments are also brought to the surface; these bacteria decompose the organic material from the bottom, using up oxygen in the process. This whole event is termed a "turnover," since literally, the bottom comes to the top.
• Long periods of cloudy days-In aquatic ecosystems, the oxygen manufacturing system consists of microscopic organisms and aquatic plants that carry out photosynthesis: using energy from sunlight to create carbon-based nutrition for themselves with oxygen as a by-product. When there are long periods of cloudy days, these organisms produce less oxygen. At night, photosynthesis doesn't occur at all, and these same oxygen-producers are actually using up oxygen during respiration, just like fish and other animals. Under these conditions, it does not take long before there is little oxygen left for fish. Low-dissolved-oxygen fish kills often occur early in the morning, when oxygen levels are at their lowest.

Thanks Danny. I was curious but too lazy (and busy still cleaning up after Irma) to look through all those details. Clouds and bottom waters, that's very interesting info.

Some good pics Danny....don't think I've ever seen that slow wake sign outside of the Jolly Gator under water...a lot of dangerous stuff under water now, the bridge over lake Jessup lost (15-20) 30 ft. high street lights sheered off a ft. from base that I'm sure some ended up in the lake, that being said the start of the speck bite is sure to be delayed this year, goin to take some time before things settle down, then it's going to take some recon to find them! Back to the salt I guess......
