RedactedNarrative: On 7/15/2017 at approximately 1855 hours, Operator and his 4 passengers broke down north of the Waddell dam. This was due to the boat not starting.  The boat was anchored at the time to try and repair it. Soon after anchoring a severe thunderstorm rolled in and caused the boat to take on some water and was unable to start. The boat began to drift due to the choppy rough water. Three of the passengers were told to swim to shore and eventually the operator and fourth passenger swam to safety on shore. The Coast Guard Auxiliary came out to the scene and rescued the individuals from the shoreline. Once the owner/operator was on land he attempted to call and make a report with MCSO. Contact could not be made until later in the night. The owner was contacted today (7/16/2017) at about 1040 hours. Prior to making phone contact the boat was found on shore just north of the Maricopa County Discovery Center and west of the Waddell dam. No Injuries were reported. Owner is going to file a claim with American Family insurance and will remove the boat from the lake.
