Geocache Description:

to get a picture of the Acadian Dykes from the Lr. Truro or Onslow side (FOR THIS REASON I HAVE POSTED THE CO-ORDS IN THE WATER BETWEEN BOTH SIDES) with you or your family with your GPS. To gain bonus points take a short stroll west along the dykes and you can take a picture of the aboiteau. A bigger bonus would be get the tidal bore passing by and have all three of these in one picture ( you and GPS - aboiteu - tidal bore ) **please post picture on this cache site**

Thus began the Acadians epic struggle to build a series of dykes to keep the sea water out, while allowing fresh water to irrigate the fertile land. They basically had to harness the sea, no easy task, even by today’s standards. But it was monumental, undertaking for a people using only horses, oxen, primitive hand tools and good strong backs. The Acadians started construction at the edge of the marsh where the sea had formed a natural ridge at low tide. Whole Acadian families toiled on the dykes from sun up to sun down. Since it took two to four years for the fresh water to cleanse the marshes of the salt, the dykes had to be constructed near fresh upland streams or rivers. Dykes in the Cumberland Basin measured three metres at the bottom and rose to two metres high and a metre wide at the top. At the bottom of the dyke, brush mats were constructed by laying small hardwood trees close together and alternating them end-to-end. Marsh mud and grass were used to seal the wood together. On top of the brush mat more cross ties of wood were laid. Then posts were driven at an angle into the cross ties securing the brush mat below. Sods of grass from the marsh anchored the face of the dykes further sealing off the high tidewaters. But, by the 1740s many were much larger reaching heights of seven metres high by thirteen metres wide at the base. The most ingenious feature of the Acadian dykes were the sluices or “aboiteaus” which were a series of wooden gates designed to swing open, allowing fresh water onto the land before flushing it out to sea. Afterward, the gates slammed shut keeping the sea water out. The Acadian French were the only ones in the new world to use this method of farming. It is thought, they brought the technology with them because it had been used previously in both Holland and France By the 1750s, the Acadian people had dyked more than 5,000 hectares of land. Acadian history reveals a diligent and tenacious people who survived both being torn between the warring factions of the France and England, and the banishment from their lands by the British during the Acadian expulsion, “derangement” of 1755. At Tintamare, and all around the Fundy basin, many of these dykes are still standing and functional today. The Acadian dykes truly are an engineering marvel and serve as a testament to a resilient and industrious, Acadian culture The Acadians devised a system of drainage ditches combined with an ingenious one-way water gate called an aboiteau. The aboiteau was a hinged valve in the dike which allowed fresh water to run off the marshes at low tide but which prevented salt water from flowing onto the farmland as the tide rose. These efforts were not in vain since the lands, surrounded by the dikes and drained by wooden clapper valves, were completely desalinated and extremely fertile. The immediate result was that the Acadian standard of living, while very rigorous, was greatly enhanced and this very rapidly. PLEASE ***********************JUST E-MAIL YOU ANSWER TO ME.
