[GH] Probably more than any of us need to know about TIDES. Just some things I looked up to satisfy my curiosity. Some of our salty fly fishers may find them interesting and even archive them. This may be of little or no interest to someone who never intends to fish the salt. To those with an insatiable thirst for World knowledge, read on........
We'll follow with a bit more on Saltwater Quick casts once I organize our incoming material.

[GH] While we are "on a roll" with salty stuff, I'll relay phone message from Jim Penrod.
He tells me that James McCully's easy to read and understand book on tides, BEYOND the MOON.... is now available for $15.95 on Kindle and other electronic media. This is a super bargain considering it now costs about $75.00, hardcover edition, new. I checked it out on Amazon.com. *
For our new members who haven't seen it, I've attached information I've learned about tides over the years which goes beyond this text.

I thought of titling this little message as, "Saltwater Tides", until I remembered that very large bodies of fresh water have modest tides (compared with those of Oceans). Scientists tell us that even very small lakes and ponds technically have "tides", but they are minimal... so small as to be almost undetectable by any but very sensitive instruments. **

Saltwater tides do have a dramatic effect on the rise and fall of water levels in estuaries as well as the mouths of great rivers. (Years ago, my tent got flooded with fresh water by a super high "moon tide" in the Bearing Sea even though I had camped almost 5 miles up river in N.W. Alaska. THAT was a practical lesson learned the hard way.)
Enclosed bodies of water have what some look at as a "tide". This, however, is due to what scientists call a "standing wave" or "Seiche"... kind of a sloshing of the water from one side of a lake to the other. This can be caused by anything from minor earthquakes to strong winds. These seiches, I learned, can also occur right along with real tides in partly enclosed bodies of salt water, making tidal predictions even more difficult. ***
