spring may be highest due to the effects of evaporation. The
conductivities measured at this site should not provide any major
constraints to development. High conductivity may actually prove
to be advantageous for razorback sucker habitat development as
invertebrate production is generally enhanced by high .
conductivities.

Patterns of sodium (Na+) concentrations are similar to
conductivity patterns, being highest in the north (Figure 15).
The gradients are strong with concentrations in the north thirty
times higher than the Green River and five to ten times higher
than the central wetland area.

Figure 15. Sodium Ion Concentrations in the Escalante Wetlands
During 1993 (From Cooper And Severn 1994b)

Selenium concentrations followed a similar pattern to both
conductivity and sodium concentrations. Very high concentrations
of selenium were found in waters of the northern portion of the
study site (Figure 16). No detectable concentrations o! selenium
were found in the wetland area, but concentrations were-high on
the southern end of the site. Selenium most likely is moving in
