Capitol Broadcasting Corp. plans to open the dam at the Rocky Mount Mills on Tuesday in order to inspect the turbines and the dam.
It is anticipated that the work will take about two days. During that time, residents will likely notice significantly lower water levels along the Tar River upstream of the dam. A temporary surge of water also is expected downstream of the dam once the gates are opened.
City officials are urging residents who plan to fish or to engage in other recreational activities immediately downstream of the dam to be aware of the possibility of higher than normal flows and to exercise caution.
Assuming the work can be completed in two days, flows should begin to return to normal on Thursday.
