After this occurs and once the tubes are securely in place, a hookah compressor and a low-pressure hose re-inflates them so that they form a tight grip around the floating logs. This process gives the logs more buoyancy and gives loggers easier access points to harvest them. As many tubes that are needed are used to float the logs. [4]
A "full deck" of logs awaiting the mill. A log pond is a small natural lake or reservoir used for storage of wooden logs in readiness for milling at a sawmill.Although some mill ponds served this purpose for water-powered sawmills, steam-powered sawmills used log ponds for transportation of logs near the mill; and did not require the elevation drop of watermill reservoirs.
Log boom on St. Croix River in Maine, aerial photo taken in 1973 Timber marks on a log building in Sweden where they are called flottningsmärke. A log boom (sometimes called a log fence or log bag) is a barrier placed in a river, designed to collect and or contain floating logs timbered from nearby forests. The term is also used as a place ...
Floating logs down a river worked well for the most desirable pine timber, because it floated well. But hardwoods were more dense, and weren't buoyant enough to be easily driven, and some pines weren't near drivable streams. Log driving became increasingly unnecessary with the development of railroads and the use of trucks on logging roads ...
Some timbers were carefully, smoothly hewn, and there was a demand for them, especially in England, after steam sawmilling became common. On the Altamaha, for many years during the rafting era, most rafts were made up of “scab” timber, that is, logs roughly squared by broad ax for tighter assembly and for gang sawmills which could cut flat ...
Log jams form when trees floating in the water become entangled with other trees floating in the water or become snagged on rocks, large woody debris, or other objects anchored underwater. They can build up slowly over months or years, or they can happen instantaneously when large numbers of trees are swept into the water after natural disasters .
A splash dam was a temporary wooden dam used to raise the water level in streams to float logs downstream to sawmills. [1] By impounding water and allowing it to be released on the log drive's schedule, these dams allowed many more logs to be brought to market than the natural flow of the stream allowed.
In some waterfront areas, driftwood is a major nuisance. However, the driftwood provides shelter and food for birds, fish and other aquatic species as it floats in the ocean. Gribbles, shipworms and bacteria decompose the wood and gradually turn it into nutrients that are reintroduced to the food web. Sometimes, the partially decomposed wood ...
