Summary/Recommendations/Objectives:

In White Oak Creek, surface surface
waters released downstream from the dam had higher temperatures, regulated flow
during flood events, and greater suspended loads than the waters entering the
reservoir. The macroinvertebrate communities below the dam differed from the
upstream communities.

The major differences were greater
numbers of organisms, higher densities, and shifts in species composition.
However, species diversity of these communities was not significantly different
above or below the

dam. Downstream fish samples were
also different when compared with

those taken above the reservoir.
Fish samples below the dam had fewer

fish but greater biomass because
of the presence of increased numbers of

catostomids (suckers). Above the
dam, centrarchids (sunfish) were comprised chiefly of green sunfish (Lepomis
cyanellus) and redeye bass

(Micropterus coosae), while
bluegill (Lepomis macrochirus ) were the
dominant sunfish below the dam.

The physiochemical and biological
characteristics of the sample

sites in Wesobulga Creek were
similar to the stations located above the

dam on White Oak Creek. Data collected
from Wesobulga Creek will be useful for determining the effects of dam
construction (Structure 17A) on the stream.
