Table Hy05: Missouri Department of Conservation 1998-99 Pomme de Terre Lake water level management recommendations.
FALL-WINTER (November-February)
Recommendations Flood releases should not exceed 1,000 cubic feet per second (cfs) and ramping should be utilized so that releases do not exceed a 500 cfs change within a 24-hour period. Evacuation of flood flow releases sooner than anticipated may be necessary to avoid or reduce excessive rises in lake level. Half to three-quarter bank full flows (>2,000 cfs) should be minimized throughout the year.
Benefits Avoiding artificially high flows will prevent excessive bank scour downstream of the dam in the Pomme de Terre River.
SPRING (March-May)
Recommendations Maintain lake water levels at 2 f.t above normal pool (841 feet mean sea level (msl)). When lake water temperatures reach 45o Fahrenheit, increase outflow to 100 cfs. Spring discharges should be continuous and not exceed 300 cfs. Surface water releases should be utilized as much as possible.
Benefits Elevated water levels will enhance spawning habitat for reservoir fishes from March through May. Limited, continuous releases will improve spawning habitat for walleye and white bass below the dam. Surface water release will maintain favorable water temperatures for river spawning fish.
SUMMER (June-October)
Recommendations Maintain the lake level at 841 msl until June 15. Beginning June 15, lake may be drawn down to 829 msl if needed for dock maintenance. Discharges above 500 cfs should be avoided. Outflow of at least 100 cfs should be maintained as long as possible through the summer. Lake water may need to be stored following periods of summer inflow, to provide sufficient water for continuous summer releases.
Benefits Maintaining elevated water levels through June will provide sportfish habitat and fishing opportunities in the lake. Drawdown beginning June 15 will allow shoreline vegetation to recover from flooding. Discharges greater than 500 cfs should be avoided to prevent bank erosion below the dam. Maintaining outflows throughout the summer will provide favorable sportfish habitat and fishing and canoeing opportunities below the dam.
