There weren't any changes made to number 7. What was done, was that the level of the pool below number 7 and above number 8 was raised which changed the way number seven behaves. It has become a lot less sticky and at some levels a pretty decent surf wave.
Number 8 can be a fun little feature too, however, I think that some of the fill was blown out when we had some high water in July so it may have to be replaced.
PS-Come to the Pueblo Chile & Frijole Festival Rodeo and check it out for yourself. We were promised 600-700cfs which is a decent level.
