Time to face some hard truths

Seeing the continuing horrible conditions of Arthur/Patricia beaches this year, the time has come for the residents of VB to face some harsh truths and realities.  The “foolhardy” protection of property seems to be resulting in some pretty clear consequences.

Here is a link to a very good article that is very informative about what is causing the loss of our beaches on Lake Winnipeg, including a reaction to shoreline protection:

http://www.cecmanitoba.ca/resource/hearings/33/CEC-011%20Isostatic%20Rebound%20Report%20by%20Harvey%20Thorleifson%2030%20January%202015.pdf

Here is an important excerpt:

“Shoreline protection engineering is an extremely controversial topic, and it is not within our mandate to make recommendations or to conduct research into design. I can, however, offer a few thoughts.

Engineers tend to recommend engineering, whereas geologists tend to recommend that you back off and respect the forces of nature. There is no doubt, however, that a Professional Engineer can design a means to temporarily protect a high value installation that was, through error or necessity, built too close to a retreating shore.  

Geologists, on the other hand, are quick to point out the inadequacies of shoreline engineering.

While erosion may be halted at the water line, it is essential to recognize that erosion continues underwater to a depth of several metres. Consequently, the shore armour is exposed to progressively greater wave power.

Furthermore, sand must be mobile for shoreline systems to be in a state of dynamic equilibrium. According to a standard geomorphology textbook by Bloom, ʺExtensive reclamation and beach stabilization projects actually endanger barriers, because unless sand is free to move with changing wave conditions, erosion results.ʺ In SEPM Special Publication No. 48, Pilkey and Thieler state, ʺThe myriad sea walls, breakwaters, groins, and jetties that line developed shorelines divert offshore, slow down, trap, and otherwise reduce the regional beach sediment supply by longshore currents, and thereby increase erosion rates.ʺ This view is summed up on the cover of one edition of the book ʺThe Beaches are Movingʺ, by Kaufman and Pilkey, as follows, ʺthese facts provide a new ability to make informed, intelligent decisions for the coast.

This is the first book to explain why the shore must move, and how utterly foolhardy we are to armor our coast against the unbeatable force of nature.ʺ

New Pictures of the Absolute Devastation of Patricia and Arthur Beach

After years of warnings and actions by many to halt or remove the revetment on Patricia and Arthur Beach, we are very sad to report “we told you so”.

As another season passes, the beach is further beginning to look exactly like what we were told it would.  The quiet truth of science once again trumps the loud volume of the nay-sayers.  Severe scouring of the rocks has revealed rocks and stones and the further continuing removal of all and any sand from this once pristine beach, shows it is doomed.  The amount of people that looked at it this weekend with both shock and awe, was telling.   The wordless sadness at what we are losing was profound.  People simply did not have the words.

Make no mistake.  A truly great gift of a beach has been taken from many of us.  Let the pictures do the talking:

If these pictures bother you, don’t simply mourn and walk on.  Do something.  Voicing your concern to council is a very good first step.  They all campaigned on making things better on the beaches at VB.   This is an epic fail.
