The reservoir is filled to capacity, but cracking and leaking occurs that potentially could erode the dam.
Leaking reaches excessive levels and water color indicates that the rock underneath the dam is becoming increasingly porous. Dam failure is feared, but none of the remedial grouting seems to have any effect.
- April 1995
Special measures are taken to fill the rock cavities below dam level: First, 8 650 wooden and plastic balls are injected, but while they remain in place, the grout injection still fails. Lastly, 25 000 polypropylene feed sacks are injected to create a mesh inside the karsts to retain the grout. This solution proves effective. Leaking is reduced from 1600 liters/hour to less than 100.

A power surge knocks out electricity throughout Honduras. Flooding of the powerhouse almost occurs, but the turbines re-start and power the sump pumps just in time to save the powerhouse.
