Open for boating Wednesday, Saturday, and Sunday, the reservoir is situated in a valley that is bordered to the west by the Del Dios highway. The reservoir has three forks: the dam to the south-west, the mangrove type marsh to the south-east, and the freeway to the north east. There are several 'no-wake' zones situated in convenient locations close to the shoreline, and they provide for a nice, calm paddling experience.
My most recent adventure took me to the eastern fork, where there is a hidden creek that feeds the lake. The creek is small; however, it seems like a mangrove swamp once you start traveling inward, and provides for some great photo opportunities.
If you do intend to travel to the south eastern creek, I would recommend staying on the southern shoreline for the duration, as the lake can be quite windswept due to it being situated in a valley.
