Unit 1: Welcome To Stream Crossings
Stream crossings are often necessary to complete a logging operation. Because stream crossings have direct contact with the stream, care should be taken while installing or removing stream crossings so that there is as little impact as possible to the streambed and water quality.
The first thing you should decide when planning your road system and stream crossings is whether or not you actually need to cross any stream. Here are some questions to ask yourself before you decide that a stream crossing is necessary:
Unit 2: Stream Crossings
Dirt crossings are not recommended and should never used.
Unit 3: Factors to Consider when Planning a Crossing
Once you have decided that a stream crossing is necessary, several important factors will help you determine the appropriate crossing to install. These factors are:
Taking these considerations into account before installing a crossing can help you stay productive while minimizing the impact to water quality.
Unit 4: Selecting an Ideal Stream Crossing Location
Selecting the location of a stream crossing is just as important as determining the type of crossing to install. When choosing crossing locations, you should look for the following:
Think about how you would evaluate the stream on the left for the above listed factors and then think about how you would cross it.
Unit 5: Permanent Vs Temporary Crossings
Crossings which are intended to be left in place to allow for access to the tract with as little impact to water quality as possible.
Crossings that are installed for a short period to allow access to the tract during an operation, and are removed after the operation is complete. Often the types of materials used to construct a temporary crossing are very different from those used to construct a permanent crossing. Logging mats, logs, or brush are common materials used to construct a temporary crossing. Temporary crossings can obstruct or alter channel flow, so it is very important to remember to remove a temporary crossing after it is no longer needed.
