process was much more involved than just putting in a gate. Prior to construction, a dam safety study would be required, as well as congressional authorization. (3) Ms. Hotubee stated that the stream gauge flow was the method used to measure inflow, outflow and evaporation at Pat Mayse Lake and that it was the scientific method approved. (4) Ms. Hotubee explained they did not have the data to reflect what the daily drawn capacity of the lake would be when fully silted. She said the last sediment survey was done in 1985 and she did not know the amount of silt that had come in since then. (5-6) Ms. Hotubee said the Corps did not have plans to increase the capacity of the lake, nor did they have the funds available to improve the capacity. (7) Ms. Hotubee said that a daily average was not used for evaporation and spillway discharge in GPD. (8) As to how much water would be available in the conservation pool should a five year drought reduce the replenishing process by just 10% per year of an average annual of rainfa1142.6 inches, Ms. Hotubee reported a determination could not be calculated without review of historic data. (9) Ms. Hotubee said there were big releases out of Hugo and she wasn't sure if those would have a big impact. She also said there was a problem in that there is an endangered species in Pine Creek and identified it as being a Ouachita rock- pocketbook, a rare freshwater mussel. (10) Ms. Hotubee said she was not aware of any mandates. (11) Todd Reek said they were looking at different options and Ms. Hotubee said they would have to conduct studies to make the determination. (12) Ms. Hotubee stated the least expensive and easiest route would be to raise the dam. She said dredging was very expensive and they would have to determine if there was toxic waste. Should there be toxic materials in the sediment, it would require special handling. (13) Ms. Hotubee said the Corps were interesting in participating in improvements and could look at options to obtain funding from the federal government. (14) An environmental impact study will need to be conducted which would be part of the reallocation study. The estimated completion of the study is five years. Page 2 of 3 000024
