where a discharge of 10,000 cfs or greater (inundation of the Cleopatras Couch bar) was maintained for

a period of about two months (Figure 1.2), were to:

. resurvey the established cross sections at Mathers Hole and Cleopatras Couch

. re-sample the bar sediments at both sites to determine if there had been significant changes in
the sizes of the sediments

. establish three new cross sections within the pool upstream of the spawning bar at Cleopatras
Couch to enable the HEC-2 model of the site to be extended upstream so tl1at sediment transport
through the pool could be modeled.

A second objective of this report was to present the results of a comparison between one-
dimensional (1-0) and two-dimensional (2-D) hydrodynamic modeling of the Mathers Hole spawning bar.
