1994 Grumman A-6 Intruder Incident
- On October 14, 1994, a US Navy training plane, the Grumman A-6 Intruder, crashed near the reservoir.[2] The A-6 Intruder took off from NAF Atsugi in Kanagawa Prefecture, and was headed towards MCAS Iwakuni in Yamaguchi Prefecture. The plane crashed on a low-level flight following a river when it got to a bend and couldn't get out. The wing sliced into the water upon a reverse. Both pilots, Lt. Eric A. Hamm and B/N John J. Dunne, Jr., were killed in the crash.
Water Supply Crisis of 2005
- The Sameura Dam supplies water to Takamatsu, Kagawa Prefecture and Tokushima Prefecture. In 2005, because of little rainfall and a series of dry spells from April to June, the Shikoku Region was hit by a very serious drought and Lake Sameura dried up twice.[3] Luckily, they could get over this crisis thanks to the heavy rain brought Typhoon Nabi.
