This applet may take a few minutes to start, depending upon the current load on the Tulsa District WCDS database and the speed of your Internet connection.

If the applet does not start, your browser, even if it supports Java, probably does not support applets written to Java Development Kit (JDK) 1.1.x

JDK 1.1.x compatible browsers include:

• Microsoft Internet Explorer 4.01 and later.
• Netscape Navigator 4.05 and later.
• Sun HotJava 1.1.2 and later.

Summary:

The red curve on the graph is the lake capacity (the amount of water in the lake) at a given elevation. A dashed red line on the lower part of the curve may be present. This is the region below the first point on the curve. This line is generated from a linear extrapolation from the first point of the curve to the elevation at which the lake is completely dry. Similiarly, a dashed red line may appear on the upper part of the curve. This is the region above the last point on the curve. This line is generated from a linear extrapolation from the last point on the curve to the elevation of the top of the dam.

Instructions:

• To use a Mouse: Click on a point on the chart to show a marker on the curve or drag the mouse along the curve to obtain a variety of values while a marker is shown.(/LI)
• To use the Keyboard: Type in a value in the edit box on the lower part of the program to calculate the lake capacity. The "Compute Now!" button may be used in two ways:
  • Compute Capacity from Elevation. Press the radio button labeled "Compute Capacity from Elevation". Entering a carriage return or pressing the "Compute Now!" button causes the program to read whatever is in the ELEVATION edit box and compute the lake capacity at that elevation. The resulting capacity is placed in the CAPACITY edit box and a marker reflecting these values is shown on the graph.
  • Compute Elevation from Capacity. Press the radio button labeled "Compute Elevation from Capacity". Entering a carriage return or pressing the "Compute Now!" button causes the program to read whatever is in the CAPACITY edit box and compute the corresponding elevation. The resulting elevation is placed in the ELEVATION edit box and a marker reflecting these values is shown on the graph.
