Improving river aeration at underflow dam
Aeration occurring in flow through dams can be significant contribution to dissolved oxygen resources of river receiving oxygen consuming organic material of waste waters; aeration rate at Lock and Dam No.2 on Mississippi River near Hastings, Minn, had been reduced by factor of three by increase in tailwater elevation resulting from construction of another dam downstream; conversion of underflow gate structure to overflow condition almost restored lost aeration capacity; aeration at dams can be improved through changes in operation; contribution of dams to river-dissolved oxygen resources should be included in consideration of dam design and operation.
