INFORMATION RELATING TO THE ROSS BARNETT GRAPH: The Blue line to the left of the vertical dash line is Observed Ross Barnett Discharge from gates. The Purple line to the right of the vertical dash line is the forecast inflows into the lake. Multiply kcfs value by 1000 to get cubic feet per second(cfs).
