Questions for the U.S. Army Corps of Engineers <br />1. What is the maximum lake level and minimum lake level at which the boat ramps at Pat <br />Mayse Lake are operational? Is it feasible to make boats operational at lower lake levels <br />than is now the case? <br />2. Is there a way to keep the lake level higher at the start of summer by not releasing water <br />unless the level were at 457 or above, instead of at 451? We get very little of our rain in <br />July and August, and evaporation is at its highest. Is there not a way to put a gate where <br />the water leaves the lake so that water levels in the summer start their decline from a <br />higher level? At what lake level does it become a problem in the parks, picnic areas, etc. <br />around Pat Mayse Lake? <br />3. How accurate are the Corps' data on inflow, outflow and evaporation at Pat Mayse Lake? <br />Just estimates? Is the data scientifically valid? Describe the processes through which <br />inflow, outflow, and evaporation are determined. <br />4. What will be the daily drawn down capacity of P.M. Lake when fully silted, (2065)? <br />5. Does the Corps have plans or been asked to prepare plans for increased capacity at P.M. <br />Lake? <br />6. Are there funds available through the Corps to improve capacity at P. M. Lake? <br />7. At P. M. Lake what amount does the Corps use for daily average of evaporation and <br />spillway discharge in GPD? <br />8. How much water would be available in the conservation pool (415 ft. - 451 ft.) if a 5 year <br />drought reduced the replenishing process by just 10 % per year of our average annual of <br />rain fa1142.6 in. ? <br />9. Would the reduction in current spillway overflow (if water was diverted prior to the <br />spillway) create problems downstream on flowage requirements within the Red River ? <br />10. Does the Corps require (mandate) certain flows through P. M. Lake that would prohibit <br />City redirection (sale) of water that never reaches overflow capacity? <br />11. Would the pumping of water from Lake Hugo into P.M. Lake create problems P. M. <br />Lake was not designed to handle? (Quicker silt accumulation, less flood control, water <br />quality, plant. animal or recreational issues) <br />12. If P. M. Lake's capacity was to be increased which method dredging, raising dam, or <br />moving upstream would increase capacity the best and be the most economical to <br />accomplish? <br />13. Would the Corps be interested in participating in future P. M. Lake improvements <br />relating to capacity building? <br />Exhibit "A" <br />. OODU211, <br />
