i of 605.5 total pond sites, while the 15 partial owners of pond sites own a total of 7.5
ponds.
' Colorado State Parks manage the most public pond sites (33) followed closely by
the CDOW, Bureau of Land Management, Bureau of Reclamation, and the City of
Grand Junction with 31, 30, 29, and 27 pond sites, respectively. Clifton Sanitation
District owned the most municipal pond sites (15). Five private entities own a significant
number of ponds, with two entities owning 12 ponds each, and three entities owning 11
ponds each.
Pond Access -- Access was sought primarily from landowners who owned
multiple ponds. However, willingness of landowners to allow access played a major role
in which ponds were sampled/controlled. Between 1996 and 2002, access was
obtained from 76 private, 6 public, and 10 municipal landowners to investigate 188, 75
and 66 pond sites, respectively (Table 4). The number of pond sites examined each
year is reported by river basin in Table 5. More pond sites were examined in 1999 than
any other year of the study. The number of landowners that declined participation in the
NNFC program was not recorded.
