Research Results
Anomaly A11 was identified based on a sonar and magnetometer targets from the 2005 remote sensing
survey. In 2010, the area was investigated with side scan sonar, scanning sonar and visually from the
lake surface (Figure 77 and Figure 78). In 2011, diver verification conclusively identified Anomaly A11 as
a series of modern pipes or conduits which had been discarded on the lake bottom.
Recommendations
LCMM recommends no further work for A11.
