STATEMENT OF WORK
SUMMARY
In South Texas, low annual rainfall, high o~aporation, and dive.ion of ~ water to
~upport growing municipal, agricultural and industrial neech have mbet~tially reduc~
fr~hwal~"r inflow into tim N,_,~ E.m:uary. Low fi'eshw~a' inflow t"e~l~ in
and soil~ that are diluted only through direct precipitation or by flooding of tho Nueom River

upper re~ches of lhe Nueces Mmsh had positive /uh~act~ includin~
column ~alh~ity, improv~l bnhimt quality and availability, and incr~med produ~ivity of
c~tuarine species (Bure~ of Reclmn_n~_'on, 2000).
[n Octolc~r 2001, the City of Corpu~ Christi (City) elected to co~imie f:rmhw~t~
the i~irnary diver~io~ cl~nnei in the BOR project. The City r~dug thi, ~ to · dopth of 0.3

that c~ deliver up to 3.7 x 10~ m~ rno'~ (3.000 acre-ft mo' ) fium Cahdle~ Pool to Rincon Basyou.
