Walter & Group...
[GH] Just a bit more on tides & salty things before we exit that sub topic. Then back to casting. Our next message will contain some uses for the Quick casts in fresh water.
Some interesting stuff !

[GH] From Walter Simbirski:
Gordy,
Maybe I can learn something about fresh water from this seemingly never ending diatribe on saltwater fishing? :-)
Since I'm more or less confined to my igloo due to freezing temperatures and howling winds it can't hurt to read a little bit about salt water fishing, I guess...
I had always thought that any large body of water whether salt or fresh, such as the Great Lakes, exhibited tides . After all, I had seen them for myself? Hadn't I? Based on your post I did a bit of research and came up with this great little discussion:
This actually gives me more insight into solunar activity and freshwater fishing. Definitely going to have to make a study of it this summer.
Thanks!
Walter

[GH] Walter,
To put it simply, seems we have SLOSHING as well as TEENY WEENY MOON TIDES in the Great Lakes. Water levels are also greatly affected by water that flows in and that which flows out.
I was fascinated by the info, in your links! Lots of stuff I didn't know....like the rising of the land.
Here is a link to the Solunar Tables :
Reminds me of the time one of my buddies took a picture of a really fat fellow sitting on the bow of his skiff eating a huge sandwich and downing a beer. He showed it at our fishing club meeting as part of a powerpoint presentation on solunar tables, entitled : MAJOR FEEDING PERIOD.

[GH] David Edens weighs in on tides in his area :
Gordy:
This is interesting, and I have observed similar variations in my short time permanently on the Golden Isles of Georgia.
We routinely see nine to ten foot tide fluctuations on the full and new moons in St. Simons. (Which offer outstanding fishing for tailing red fish in the flooded grass in the summer.) Our neap tide variations are normally just five feet. Today the variation is less than five feet at the St. Simons bar. (Tidal information from protides.com)
I have a question you might want to pose to the group.
Why are the tidal variations so great in the St. Simons area?
The answer is that St. Simons is located as the western most end of the South Atlantic bite, which serves as a funnel, pushing huge tides into our area.

[GH] David,
Yes, indeed ! We'll just give away your answer, this time.
Some extreme examples of the same phenomenon exist at the Bay of Fundy, Nova Scotia, and the bay outside Darwin, Australia and Cook Inlet, Alaska. Tidal bores occur with a roaring incoming wave as the tide advances. These can be dramatic, especially as the incoming tide comes up against the current of a large river such as the Amazon.
Even a freshwater lake with a tidal drainage outlet can be included. Nitinat Lake on Vancouver Island has a sometimes dangerous tidal bore at Nitinat Narrows where the lake meets the Pacific Ocean
These bores are true TIDAL WAVES ... distinct from non-tidal TSUNAMIS which are generated by earthquakes and/or volcanic eruptions under and near the Ocean.
Best,
Gordy

[GH] John Field reports on tides in the U.S. Northeast waters :
Hi Gordy,
Inshore saltwater guys can never know too much about tides. I’ll probably buy McCully’s book too. I know how important water depth and flow is for your Keys fishing and navigation. As you also know, they are very important here in the Northeast because of our coastal baitfish movements and dangerous hydrographic features. Tide is an important part of my upcoming cover-story, called “Squid in the Rips” in this June/July issue of Fly-Fishermen Magazine. Here are some tools I’m using to help visualize and predict what the tides, currents and wave action will do in conjunction with land and bottom contour.
I recently downloaded the Jeppesen Marine Plan2/Nav App on my cased iPhone. This will complement my on-board SI-TEX GPS plotter/sonar which uses basically the same C-Map software. This software overlays tides info and current direction on the map. I use (paper) local tide and map charts in conjunction with the electronic versions to plan and execute fishing and navigation. As you are aware, you will often find inaccuracies in tide charts requiring corrections for the local effects of weather, celestial relationships and bathymetrical timing delays.
Good fishing,
John Field

[GH] John,
I grew up on Long Island and fished there during my youth. Each year, I spend time in the Fall fishing those waters for stripers, blues, albies, etc. (My brother, Dave and I were out watching the trees fall during the hurricane of 1938 until we had to seek shelter.)
My guess is that you do as we did, over the years, and apply what you studied to your own observations on the water !
Scientists/Oceanographers at the Woods Hole Oceanographic Institute, Mass. have also studied N.E. tides.

[GH] For those interested in learning more about tides, there is a modern glossary of tidal terms (terms like: Chart Datum, Bench Mark, Diurnal inequality, semi-diurnal tides, harmonic constituent etc., etc.) found in an inexpensive yearly publication available through Blue Water Books and Charts, www.BluewaterWeb.com (800-942-2583)
It contains tidal constants/differences as well as official U.S. datums, Moon tables, Sun tables and conversion tables. *
I keep a current copy on my desk and us it regularly. (Printed yearly).

[GH] Golden advice for those of you who plan a saltwater wading trip in the tropics, from Jim Penrod :
Hi gordy,
Regarding sting ray wounds. Long ago when I went through submarine medicine school we spent a fair amount of time on marine hazards. If one does get barbed by a sting ray get to a hot water supply as quickly as possible. The toxin is heat labile and is inactivated at 106 degrees! Plunge the affected part into the water and leave it there several minutes. Relief can be almost instantaneous but be forewarned all the toxin may not be inactivated. You will know immediately because the pain will become intense almost immediately after the affected body part is removed from the water. Plunge it back in and wait several minutes. You will know when all is inactivated. Wash very well with soap at this point and observe over the next several days.These are very prone to infections!!
Sequence of pain (from personal experience) Struck on heel. Initial sensation is like being stuck with a sharp pin except someone leaves the pin in and keeps jabbing. Pain radiates along the foot and starts up the lower leg and becomes more intense .Pain continue to ascend above knee to and becomes intensely throbbing involving the foot and all of the leg. It took half an hour to get to hot water. By then I was pounding on the car seat as hard as I could to combat the pain. At last, water as hot as I could stand it. Blessed relief. I made the mistake of pulling my foot out of the water to relieve myself-the pain was very intense as not all of the toxin was inactivated. Back into the hot water.The area developed a little red spot and then scabbed but was uncomfortable three weeks later. I peeled back the scab and out rolled pus- a walled off abscess fortunately for me which drainage fixed.
I hope that no one has to make use of this information but the relief is amazing!
Jim

[GH] Jim,
Yes. Over the years I've operated on several patients who got severe infections when the barb broke off in the foot. One resulted in amputation.
At our fishing club, periodically, the Dr.s who are members give an on-the-water first aid course.
We always include what you taught, above.
Heat can inactivate many marine toxins including those from various jellyfish and even Portuguese Man 'O War stings.
One trick we teach is to place a rag around the water intake of an outboard motor and run it until it begins to overheat .... not enough to ruin the engine, but so it yields hot water from the exhaust. Let it run on the wound to get some relief. Doesn't work well if the barb is deeply embedded, because the heat doesn't get in that far.
We teach the finger ring removal tricks for use when tropical insect stings or spider bites occur. This can result in avoiding the loss of a finger when the circulation gets cut off as the swelling mounts below the ring. (One of them is the string trick which you probably know.)
We teach and demonstrate hook removal techniques, CPR, and many other things as well.
