Straint

There was a dam built into the middle of an important river;
the construction materials were shoddy but it was over-engineered;

much ado was made about the environmental impact;
yet move ahead we did with the blockage, with tact;
many did move out of the new lake's way; 
resettled in less than traditional accommodations;

we said it was worth it and sometimes still do;
but we don't walk on it anymore so we do not rue;
that which was built is no longer sure;
a breakage would bust this thing that was pure;

projected to last for a generation more;
down with a breeze it likely could tore;
now all do is hold up each breath;
hoping that dam does not lead to death.
