Update: The fine folks at NLR Parks have repaired the fountain and water is on at the NLR end of the BDB.
My friend Mooney and I rode up to the BDB on a recent evening, and found that the fountain head at the NLR pavilion was off of the base and water was flowing freely. We contacted the folks at the city and the water was shut off. It was still turned off last Saturday and it may be off until warmer weather. There is still water available at the host site (there has been a large RV there) to the left of the nasty restrooms at Cook's Landing parking lot. To my knowledge, all of the water has been turned off for the winter on the Little Rock side.
