Instructions for Using the Lake Level Page
The Home page displays the last reported values for each sensor on the selected station. The table that shows the information consists of the sensor name, the value of the sensor, the units for the sensor, and the Timestamp for that report. The text for data that has reported within 35 minutes is Black. Data that has come in after 35 minutes, but within 24 hours is Blue, and data that is over 24 hours old is Red. Stations can be selected by using the drop-down box near the lower-left corner of the web page, or by selecting a map and clicking on a station on the map.
The Graph page, as its name implies, is where sensor reports can be plotted verses time. The user may select sensors from different stations, or all from the same station. When the Graph page opens, the graph will be empty.
Selecting the Sensors to Graph
In order to graph the sensors, the station to which the sensors are connected, must first be selected. There are two ways to do this.
1. Select the station from the drop-down box in the lower left corner of the web page, or
2. Click on the station on a map in the lower right quadrant of the web page. If the station is
already displayed in the “Add Station” drop-down box, then click on [Manually Add Station].
Each time you click on [Manually Add Station], or on any station on the map, a Sensor row will be added to a small table just beneath the empty Graph box. The default sensor (alphabetically by name) will be displayed. You can select a different sensor by clicking on the drop-down box for that row and selecting the sensor that you want. Additionally, the color for each sensor can be changed. To remove a sensor from the group being graphed, click on the [x] at the end of its row. A group of sensors can be saved so that the user doesn’t have to repeat adding the same sensors to be graphed each time. Enter a name in the white text box below the sensor table, and click on [Add These Sensor to new Graphing Group]. To graph those
sensors, select them in the drop-down box to the right, and then click on [Select Group to Graph]. A group can be deleted by selecting it from the drop-down box, and then clicking on [Delete].
Selecting the Graphing Period
The calendars to the right of the empty graph are used to select the start and end points for the period to graph. The bottom calendar defines the end point and defaults to the current month, day, year, and time. The calendar above it defines the start point and defaults to one week prior to the current date and time.
1. To change the month(s), click on the ≤ or ≥ at the top of the calendars.
2. To select the day(s), click on the desired date on the month.
3. To change the time (hours, minutes, and seconds), use the drop-down boxes below the
calendars for the appropriate period (start or end).
4. Click on [Draw Graph] to graph the sensors over the selected time period.”
In 2008, monitors were put in place in 8 County Owned lakes (Lake Arrowhead, Cottonville Lake, Easton Lake, Fawn Lake, Lake Camelot – upper & lower, McGinnis Lake, Peppermill Lake and Lake Sherwood) to track the water level at each dam. With these monitors, the public can now check to see where the current level is on a particular lake at any time, or use the graph function to track the history of the lake level(s) for a specific time period. These monitors also have an alarm function to alert Land & Water Conservation Department Staff if the lakes are above or below a safe level to allow the department to take the necessary action more quickly.
- Easton and Cottonville are not reporting lake levels currently.
-Lake Sherwood is experiencing technical difficulties, however, the base levels are accurate. Please ignore the spikes on the graph.
-All “Sensor Levels” are reported in Decimal Feet, not inches.
