After conducting some research, it appears that the boat ramp named South Carpenter Road 6599 in Orange, Texas is managed by the Sabine River Authority of Texas. This boat ramp is located on the Sabine River and services boaters looking to access this body of water.

As for the size of the boat ramp, I was not able to find any specific information on its width. However, based on satellite images and pictures available on the Sabine River Authority's website, it appears to be a fairly standard-sized boat ramp with enough space for multiple boats to launch at once.

In terms of the types of watercraft allowed on the Sabine River, the Sabine River Authority lists the following as permitted: recreational boats, fishing boats, canoes, kayaks, and other non-motorized vessels. It's worth noting that the Sabine River Authority does enforce certain regulations, such as requiring personal flotation devices and prohibiting alcohol consumption while boating.

Overall, South Carpenter Road 6599 appears to be a relatively standard boat ramp on the Sabine River in Texas, offering access to a variety of recreational and fishing boats, as well as non-motorized vessels like canoes and kayaks. Get driving directions.
