Appendix 6.4(3). Concluded 



Transportation Embankments or Utility Canals and Borrow Pits 



- dredged canals and borrow pits flanking either a raised, continuous 

 artificial embankment constructed for movement across a wetland 

 area or a canal flanking a powerline system across a wetland. Not 

 all powerlines have canals associated with them; however, there are 

 a number of canals of this type in the Sabine-Neches river valley. 



Pipeline Canals 



- all dredged and flooded pipeline routes. Very few open canals exist, 

 and most of the lengths are actually pipelines which have once been 

 backfilled but are now flooded due to erosion or compaction. 



Wildlife Management Impoundment Canals 



- canals dredged for navigation, drainage, or impoundment of areas 

 specifically used in wildlife management programs, whether public 

 or private. 



Others 



- canals and embankments not fitting into one of the above cate- 

 gories.
