What Values Will Drive The Next Decision

To all members of the Port Dover Waterfront Preservation Committee and all Friends of Silver Lake:

 Eric D’Hondt, Norfolk County’s General Manager, Public Works and Environmental Services, has tabled for Council’s consideration a “staff report summariz(ing) investigations and preliminary design activities… related to the Misner’s Dam.” His report in its entirely can be accessed by clicking on the link at the end of this post.

  Council will take this up at its Council meeting this coming Tuesday, February 26, 5pm. Mr. D’Hondt is asking for direction from Council inasmuch as the bill to deal with the Misner Dam is now presented and as well is  in excess of the presently budgeted 1.3 million dollars.

 ” The ability to accurately estimate the cost of the IDF mitigating measures is complicated as working solutions have not been completely defined. Notwithstanding the costs external to the dam structure, the cost to provide a structurally sound dam, is now estimated to be in excess of $2,500,000 (includes the fish ladder required by the DFO and the 25% contingency noted in Attachment No. 2). The additional cost for the dam repair is beyond that estimated in previous reports ($1,300,000) due to the now expected need to provide piling for structural support. An order-of-magnitude cost for the additional water control works (ie, such as spillways) is $10,000,000 as shown in Attachment No. 2.” [See page 3 of Mr, D’Hondt’s report.)

 The central factor driving this vastly different assessment is the requirement to deal with a flood resulting from a storm event very much in excess of what we experienced with Hurricane Hazel back in the mid-50’s.

 “Using the MNR standards, requirements, accepted practices and methodologies CRA [Conestoga Rovers Associates] has produced the IDF [Inflow Design Flood] for the Misner’s Dam in Port Dover. This is the storm that must be used as the “design storm” for any design work for the dam. … The CRA IDF consists of runoff generated by a storm with 420mm of rainfall over a 12-hour period. This is a massive storm far above any storm event Norfolk County has previously considered for any other purpose. This is 50% more rainfall than the famous Hurricane Hazel storm. Also the IDF rainfall occurs in one quarter of the time of Hazel, making it much more intense than Hazel.” [See page 9 of  the Vallee attachment.]

 If the restoration of Silver Lake, the continuing viability of our marine industry, harbour, and beaches, is of vital interest to you, then you should consider attending this upcoming meeting of Council to hear for yourself as Council grapples with what is now a difficult problem. Your attendance reinforces to Council how vital this matter is to the Community.

Asian Carp and Snake Head Carp the next big threat to our waters !

Meeting of The Birds of Directors

Meeting of The Birds of Directors

This serene picture of Silver Lake was taken where there was still some water to be enjoyed this past summer. We chose this picture because of Tim’s humourous title and today’s message is coming from the Board of Directors of the Port Dover Water Front Preservation Association.   The message however is not serene and concerns a serious situation we are potentially facing in Norfolk County as well as other areas that border our Great Lake Waters.

The Board of Directors of the Port Dover Waterfront Preservation Association would like to bring the following seminar to the attention of all members. It is their opinion that   the removal of Misner Dam   would  allow species such as the Asian Carp and Snake Head Carp to enter Lynn Waterway and other rivers that flow into the Great Lake Basins.  We are now facing a  disastrous situation that could  be controlled by restoring the dam and not constructing fish ladders.  If you are concerned, consider attending the seminar described below on Feb. 21st.

THE GREAT JUMPING CARP CAPER – Illustrated Talk by David Frew

Thursday February 21 at the Port Dover Harbour Museum
“Just when you thought it was safe to go back in the water…”

Back in the 70s, a rubber shark in a blockbuster movie made the whole world leery of ocean beaches.  Now it seems to be happening again – only this time the terror is in fresh water. According to the some scientists it is just a matter of time until huge carp make their way into Lake Erie, where they may change everything that we have ever known about the Great Lakes.  These invasive refugees from southern catfish farms escaped during high water cycles in the early 1990s.  They slithered across corn fields and found their way into the Mississippi watershed, which is now joined at Chicago to the Great Lakes, thanks to manmade locks.  As these monster fish – some of which can jump ten feet into the air – head north, they are killing sportsmen, annihilating native species and destroying bottom structures.  Are perch and walleye doomed?  Could we possibly eat them?  Are we eating them already?

You can find out on Thursday February 21st when the Port Dover Harbour Museum hosts David Frew’s fascinating illustrated talk on the latest invasive species to threaten our lake. David is a professor at Mercyhurst College in Erie, Pennsylvania and the author of a series of books on Lake Erie shipwrecks as well as his popular volume on Lake Erie rum running, Midnight Herring.

David is one of the Harbour Museum’s most popular speakers and this is the initial presentation in the museum’s annual Harbour Lecture Series. Admission is $5.00 at the door

Port Dover Harbour Museum – 44 Harbour St., Port Dover (519) 583-2660  www.portdovermuseum.ca

In the meantime, we are confident that Tim will get us the first pic of a Snake Head Carp when it makes its way past his idyllic work shop and Bryn decides to go hunting for snacks.
