There were some recent changes to Mayan White Water
. 's write up of the Macal : much of the Mollejon dam to Black Rock run (previous write up) is now flooded by the new lower dam.Greg now divides the Macal into two runs 1) whats left below the lower dam ( the run by Black Rock I referred to) as well as the long nature float to town or a lodge take out.I think you you should still be able to get at the rapids just above Vaca as well, unless dam property extends down that far. 2) a run above Mollejon that few if anybody had done since the early explorations :from Guacamallo Bridge to Mollejon reservoir,has several 3/4 rapids and one big V,plus added attractions ( see good pic and write up).The bridge is on the way to Caracol,a huge Mayan city /ruins in remote jungle.Brittish Rambos do/did their jungle training around here.
The new reservoir apparently floods all the way up to and part way up the Rio On, so impacts the logistics on the Privassiion ower run too.
