The
Smith River tailwater originates below Philpott Dam in Henry County,
Virginia. Philpott Dam is operated as a hydropeaking facility by the
Army Corps of Engineers and the river fluctuates between 25 and 1,400
cfs almost daily. The fluctuating flows are challenging to aquatic biota
in terms of fish growth, reproduction, and the production of aquatic
macroinvertebrates. Additionally, the rapidly fluctuating flows present
a safety hazard for anglers and other in the river.
Current
issues with the fishery noted by state biologists and anglers are the
lack of large brown trout and apparent slow growth of brown trout.
The
Smith River project at Virginia Tech is designed to answer questions
about:
- the best flow regimes for managing
trout growth and persistence through stream temperature control
- determine baseline conditions for brown
trout growth, distribution, and survival
- evaluate the nongame fish community,
including one endangered species
- determine levels of aquatic invertebrate
forage
- identify the roles that the tributaries
play in defining the main channel community
Results
from this Virginia Tech study will provide fisheries managers, local citizen,
anglers, and the Army Corps of Engineers with information to assist with
decisions on how to best manage the Smith River.
