Report
This report recommends that all monitoring on the Dan River be
discontinued.
It is our opinion that the fish tissue monitoring of the- Dan
River should continue at all stations. This monitoring can be scaled
down from the current level of twice a year to only once a year _and
the analysis needs to be only for selenium. This recommendation is
made because tissue concentrations of selenium at the first station
below the ash basin discharge are still elevated 3-4 times the
upstream concentations.

Recommendations #1 and # 2 should be allowed under the
condition that some effort be used to address chronic exposure
problems as evidenced by reproductive capabilities. It should be left
up to the Duke staff to decide on the most efficient way to
accomplish this goal. A couple of techniques that could be used are
1.) monitoring between year trends in selenium in the ripe ovaries of
largemouth bass ;collected from the lake during the spawning season
2.) using enclosures to hold adult largemouth bass during the 90 days
prior to spawning and then determing the reproductive fitness of
these individuals!'in ponds.
