MIS-INFORMATION and Frequently Asked Questions

Q: Are we evacuating Harsens Island (or any other areas)?

A: No, not at this time

         The County and each township is doing everything possible to make sure that evacuation is not necessary. In order to the plan for the worst possible scenario, a WINS alert was sent to Harsen's Island residents asking if shelter would be necessary in case of evacuation. 

Q: What would cause an evacuation?

A:  The only reasons for evacuation would be "Life and Safety" issues such as extreme contamination or if emergency services cannot access areas of the island (or the Island as a whole).  Unlike winter ice ferry closures, this will be a long term event.

Q:  How high will the water levels rise, I hear .... I saw .... but the levels are down from last week?

A:  Yes, even the official sources listed on this page by the Army Corps of Engineers are aged and are an estimate.  Our concern at this point is that in many places water levels have already reached record levels and several properties are flooding.  The water levels always peak in July. Additional concerns are winds can add 2" to water levels, possible weather events and seasonal rains, and boat wakes will reach much farther inland due to already flooded conditions. Short answer is this event will impact every resident on the island and many on the mainland.

Q: How do I know if I will flood?

A: See the below links on this page to find out if you are in a flood plain.

Q: What should I do?

A:  The time to act is now. There are steps you can take to prepare for increasing water levels. We have compiled both specific and general flood information on this page. There is very little action that can be done once flood waters are already impacting your property.

Q:  How do I get the latest information?

A:  The latest information will be posted on this page.  Also, sign up for WINS on the "Alerts" tab. This will be our primary way of getting information and "Life and Safety" alerts to residents.  

Q:  I have mobility issues, how will you know I need help if the situation gets worse?

A:  When signing up for WINS, there are areas where to list your disabilities.  Please keep in mind that these represent severe disabilities.
