The resultant sand or cobble substrate would likely promote the
development of a cottonwood/willow dominated community. This may
or may not be detrimental to enhancing razorback sucker nursery
habitat at this site, but would certainly result in lower primary
production. This potential change in the wetland community. and
its effect on the river system is something that needs to be
carefully monitored as this plan is implemented.

Wetlands Water Chemistry - Water collected from wetland ponds,
ground water wells and the Green River was analyzed for cations
and anions, conductivity, sodium and selenium. The north end of
the site is fed by ground water from a saline source and has much
higher conductivities than the southern area (Figure 14).

Figure 14. Conductivities (us/cm2) Measured in the Escalante
Wetlands During 1993 (From Cooper and Severn 1994b)

Conductivities in the north range from 10,000 us/cm2 to more than
30,000 uS/cm2. Conductivity in the south is as low as 254
uS/cm2. Irrigation return flows discharged from springs during
the summer appear to influence wetland water chemistry enough to
lower water conductivities. However, conductivity in the
northern area remains high throughout the year. Sampling in the
southern portion indicates that conductivity in winter and late
