Page 14, Potential Destruction, Lines 8 and 9 - More information is
needed on why and where habitat will be destroyed through excessive
siltation. We believe the statement that "habitat will be destroyed
C ~ through excessive siltation" is in error and ignores the natural hydrologic
potentials of the river and actions of floodflows which will not be
diverted.
Page 14, Potential Destruction, Lines 13 and 14 --The description of the
La Verkin Springs Unit is not quite correct. The sentence
. through a series of low profile, collapsible dams" should be
changed as follows:
" by bypassing riverflows around the springs through use of a
low-profile dam and pipeline; and collecting the springs flow
behind a low-profile control dam."
Page 15, Second para raph - Virtually all irrigation structures and all
allocations of the Virgin River waters were established by the early
C 2 1900's. An analysis of population projections, water rights, and water
needs shows that significant changes in the habitat of the Virgin River
are unlikely.
Page 16, Conservation Efforts - Add the city of St. George as funding
the Vaughn Hansen study.
B ~ ~ Page 22, Item 245 - The Bureau of Reclamation is opposed to designating
as critical habitat those areas where woundfin are transplanted. We
feel that such action would- establish a dangerous precedent.
Page 23,-Line 6 - The reference to a specific number of individuals
B 4 seems arbitrary. On what scientific data was it based?
Page 23, Item 11 - You state that "Some of the habitat in the Virgin
C ~ River obviously cannot support woundfin . . . ." Why, then, is the
entire reach of the river from La Verkin Springs to Lake Mead nominated
for critical habitat?
C ~ ~ Page 24, paragraph 112,~Lines 5 and 6 - The Vaughn Hansen study provides
data on flow volume requirements for maintenance of viable habitat.
C c Page 26, paragraphs 141 and 142 - Some estimates should be given of the
•7 amount of land adjacent to the river that will be acquired.
C 6 Page 30, paragraph 245 - The Bureau of Reclamation is opposed to this
action.
Appendix 1, page 1, paragraph 1 - The statement ". no one knows if
the Virgin River woundfin population numbers are higher or lower than
37
