DAM  MO.  1

Shows  no  serious  damage  from  ice  and  floods ;  no  sheeting  has  been  displaced ;  a  few
defective  i)ieces  require  replacing;  no  settlement  has  taken  place,  excepting  at  the
abutment,  where  it  is  about  1  inch,  the  water  spilling  uniformly  over  the  remainder.
A  slight  settlement  shows  in  the  abutment  above  the  dam.    The  dam  leaks  badly  and
will  require  about  5,000  cubic  yards  of  backing.    The  breach  remains  in  aboat  the
same  condition  as  last  year.    Considerable  breach-cribbing  was  washed  away  doting
tho  spring  freshets,  that  remaining  being  in  a  very  bad  condition  and  of  little  use.
The  foundation  of  the  lower  inside  guide- wall  is  in  a  very  precarious  condition.     Now
work  has  been  constructed  from  an  elevation  of  about  11  feet  above  tho  lower  miter
sill  to  within  a  few  feet  of  the  top  of  the  lock-wall.    This  new  work  has  been  set
back  from  the  face  of  the  old  cribbing  about  2i  feet,  the  old  cross-ties  bciof^  gener-
ally without  bearing  and  rotten.    This  projection  Is  very  dangerous  to  navigation,
and  the  entire  wall  should  be  reconstructed  before  adding  additional  height  to  it.
