2. Place sediment traps at strategic locations within the backwater to determine sediment deposition
rates at varying flows and times of the year. Compare to baseline information,
3, Take sediment core samples and analyze layers for selenium (and other inorganics) to determine
if flows are successfully diluting sediment selenium concentrations.
4, Sample food organisms and analyze for selenium (and other inorganics) to determine if changes,
ifany, taking place. Zooplankton, benthic invertebrates and small fish (up to 250 mm) will be
collected.
5. Sample water and analyze for selenium (and other inorganics) to determine changes, ifany,
taking place. Measure water quality parameters monthly.
6. Collect muscle plugs from Colorado squawfish using the channel area and analyze for selenium
residues.
7. Analyze data and prepare draft and final reproductive reports. (This report will include Adobe
Creek data also.)

Objective 2:
I. Analyze data and prepare draft and final reports for the remediation study for the Walter Walker
site.

FY 98 Work
Objective 1:

According to Steve Hamilton (2/18/98), a draft report on the 1995/96 razorback sucker reproduction
study will be out for review in April 1998; a draft report on the pre-water-control structure channel
(remediation) study in summer 1998; a draft report on the 1996/97 razorback reproduction study in fall
1998; a draft report on the post-water-control structure channel (remediation) study in March 1999.
