Plans for Fish Passage for Lock and Dam replacement could spell disaster for lake levels during droughts

Following is a comment on "Balancing the Basin" site by one of our members.

"The numbers given in this explanation indicate drastic problems for lake level control. At present release rates from Thurmond of 3600cfs or higher are acceptable downstream.  Release rates higher than 3600cs during droughts cause drastic drops in lake levels. The design basis for this project should be based on 3600cfs or less, not 5,000cfs and higher.  The Corps knows these numbers well.  All lake stake holders need to demand a more rational design basis which includes protection against negatively impacting lake levels during drought conditions."

Save Our Lakes Now agrees with these comments and recommends a totally different design basis for the fish passage.  What the Corps is proposing now with the fish passage being put in replacing the current Augusta Lock and Dam could exacerbate lake level problems during droughts to intolerable extremes. The current design proposal shows a 2ft drop in river level along the shores of Augusta and North Augusta with release rates from Thurmond of 5,000cfs.  Apparently release rates from Thurmond dam below 5,000cfs would drop the river at Augusta and North Augusta to unacceptable levels with the fish passage.  The corps knows full well 5,000cfs release rates from Thurmond dam during droughts can literally destroy our lakes.  This design basis is unacceptable and we need to insist on a more rational design basis that protects both lake levels and river levels at Augusta during the worst droughts of record.
