The crystal tank had dropped to about 4 cm from the top. There was still enough water to overflow the reservoir and run the Ram Pump.
We finalized the work on the pipe under the mountain by once again pushing the rods through. We found no obstructions, so we have a clear line from the Ram Pump to the "crystal tank".
The next logical next step was to survey the line right up to the Nacamento looking for any anomalies.
Unfortunately the levels was uniformly low all the way up and into the tunnels.
This picture is of the highest flowing water pool of El Rio and is waist deep at the top end with a small waterfall.
We determined on Day 4 to venture into the tunnels.
