Question about wave action on inland lake.
Hi,
I have a boat on Lake Lanier in GA. The other morning I took it out, and the overall wave action appeared to be different than usual. It was a flat calm day, except when a passing boat produced some waves. Most of the time the waves seem to be sort of peaked and a bit sharp, but on this morning they were more rounded and flatter. The first boat I noticed it from, I thought it might be simply due to the shape of the boat itself. But after a while I noticed it was true of all of them...which was cool with me because it meant I could go faster without getting tossed in the air too much. It still made me wonder *why* though. Could it have something to do with what creates high and low tides, and/or why sometimes when you dig a hole you seem to have more dirt than you took out and sometimes you seem to have less? If so, is there a way to predict when waves will tend to be sharper and when they will tend to be flatter, like people can predict high and low tides? |

Question about wave action on inland lake.
My guess is air temperature and pressure, and the water temperature.
Course, it could have been an oil slick too, or some other chemicals doing the same thing. Greg Luckett wrote in message ... Hi, I have a boat on Lake Lanier in GA.

Question about wave action on inland lake.
Was the water temperature different then normal? Both viscosity and surface
tension vary with water temp which may explain the differences. Can't help you on the hole and dirt observation. Suggest you try the gardening news group :-) wrote in message ...

Question about wave action on inland lake.
As I recall, wave shape, frequency and height is determined by the 3 main
factors of wind speed, fetch (distance of open water) and water depth. If you have a shallow body of water with only a modest wind speed of 15 mph over large fetch, such as the Chesapeake Bay, this will result in a constant chop of waves very close together in frequency. Conversely, the same wind speed over a smaller fetch, such as a deep inland lake, will produce smaller waves that are shaped quite differently. The waves you mentioned are produced by a boat rather than the wind, but I wonder if the same principles apply here as well. Perhaps the water depth where you witness this wave action was very deep and had an effect upon the wave shape. wrote in message ... Hi, I have a boat on Lake Lanier in GA.

Question about wave action on inland lake.
Could it be...
+ There was something in the water, like more weads or growth, that kept the waves from building? + There was oil on the water. I've heard that even a thin layer of oil will effect wave action. + That normally, but not this day, there is some wind that catches even little waves and makes them a little more pronounced? + That normally, but not this day, there are lots of other waves from either wind or boats that cause interference with all the waves and make them all more pronounced? Just guessing around. |

[...] Whether it has anything to do with the amount of dirt in holes, who knows. That phenomenon has to do with relative compaction---a lesson I learned as an enginering student trainee with the California Dept. of Transportation many decades ago. Mark Borgerson Thank you. What influences relative compaction? |

At Holiday Marina. I don't fish, but if you'd want to hook up and go for a boat ride--houseboat, runabout, and/or paddle around in a kayak --let me know. So far I haven't met anyone from a news group, and that would be cool for me. I'm at R17. Give me a call at 678-714-5764, or an email at sometime if you want. If you send an email be sure to mention something about Lanier or the like so I know it's not spam, 'cause I get about a hundred spams a day. |
