The Washington State Department of Inland Waters has issued a High Tide Warning for all Seattle area interior waters including Angle Lake. The warning will remain in effect through Saturday, April 2nd. Those who live in a location that is prone to tidal flooding should be prepared for flooding over the coming days. Minor shoreline flooding will occur during Friday morning’s high tide and may elevate to moderate flooding during the next high tide in that evening. The city of SeaTac is hosting a sandbag filling station on the northwest corner of the City Hall Parking Lot. Effected residents may claim up to 100 sandbags each in an effort to assist in reducing damages to property due to flooding. Refer to the city flyer for further details.
It is not unusual for the lake to experience higher than normal tides in the spring but when compounded with the excessive amount of rain recently, the upcoming tides are expected to be astronomically high and are anticipated to exceed the highest recorded watermark set on April, 12th, 1947 when tides were measured at 14 feet 8.5 inches above the average water line.
Residents are being asked to relocate all boats, beach furniture and other property at least 20 feet away from the beach to prevent any items from being inadvertently carried away. An additional reminder, all beach property should be labeled with the owners post number for easy identification in the event that items become misplaced. Do not park your vehicle in a location that is prone to tidal flooding. Do not drive through flood waters. Since the water may be deeper than you think it is, the public should, therefore, keep away from the beaches during this time.
