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.
Stoplogs are modular in nature, giving the operator of a gated structure the ability to control the water level in a channel by adding or removing individual stoplogs. A gate may make use of one or more logs. Each log is lowered horizontally into a space or bay between two grooved piers referred to as a stoplog check. [3]
Some projects which diverted surface water for irrigation dried up the water sources, which led to a more extreme regional climate. [37] Projects that relied on groundwater and pumped too much from underground aquifers created subsidence and salinization. Salinization of irrigation water in turn damaged the crops and seeped into drinking water ...

Large woody debris (LWD) are the logs, sticks, branches, and other wood that falls into streams and rivers. This debris can influence the flow and the shape of the stream channel. Large woody debris, grains, and the shape of the bed of the stream are the three main providers of flow resistance, and are thus, a major influence on the shape of ...
Logs with a higher density than the density of water would sink. [2] Other logs would get caught in jams, sloughs, or floods, and become lodged in the riverbed. Such logs were often known as "sinkers" or "deadheads." Loggers attempted to reduce the number of logs which remained in the river in order to maximize profits, but some losses were ...

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.
