The work crew on the bank mans the ropes.

The ropes extend under the AquaDam® and circle back over and around
to the anchor pipe. On the bank the pumps begin filling the AquaDam® .

The ropes keep the
AquaDam® from unrolling
prematurely as water pressure builds inside.

Unroll and fill... unroll and fill... unroll and fill...
all the while maintaining continuous head pressure inside.   

This is the San Juan River.
The main channel is now completely blocked off.

This AquaDam® is big!
Made with over 70,000 gallons
of water!
