After conducting research, I found that the Taft Miller Access boat ramp is located in Oregon and provides access to the Crane Prairie Reservoir. This reservoir is a popular destination for fishing, boating, and water sports.

The Taft Miller Access boat ramp is a concrete ramp that is approximately 20 feet wide, providing ample space for launching and retrieving watercraft. According to the latest information available, the boat ramp is in good condition and is regularly maintained by the Oregon Department of Fish and Wildlife.

In terms of watercraft permitted on the reservoir, motorized boats and watercraft are allowed, as well as non-motorized boats such as kayaks, canoes, and paddleboards. However, it is important to note that there may be certain restrictions and regulations in place, such as speed limits and wake restrictions, to ensure the safety of all users.

Overall, the Taft Miller Access boat ramp seems to be a well-maintained and accessible option for those looking to enjoy the Crane Prairie Reservoir in Oregon.
