Dam Logs
Here are graphs showing lake levels and water flows from January 1, 2023, onward. These are made possible through our new process of using the Dam Cam.
Starting January 2024 we've changed the logging format slightly, so we're showing the graphs for the two years separately.
Pond Elevation is the lake level. Flow (before changes) is the flow over the dam prior to any changes that may be made that day to the stop logs. Stop log changes are shown as dots on the graph.
The above graphic shows the 2023 measured flows and pond levels vs. the targets set in the Management Plan or where the Management Plan is silent (off-season low, "shoulders" between in and off season), set by the TPIA.
Dam Logs Graph
The graph above shows the results of the reading of the two rulers now being used to monitor the level of the lake and water flow over the dam. For days where no reading was obtained, there is a gap. During periods of rapid lake level change there may be multiple observations in a single day.
Red shows the water flow over the dam in inches.
Blue shows the lake level as a negative number representing inches below the top of the dam. This is referred to as the Pond Elevation.
Accuracy of readings depends on the gradations shown on the rulers. The picture shows a prototype of a new flow ruler we're going to purchase once we can build a proper frame.
Dam Cam Placement
Initially, in January 2023, we cable-tied the camera and solar panel to the Dam fence for an initial test, about 5' high.
On February 16, 2023, we installed a mounting bracket created by the Dam Keeper and relocated the camera to about 6' 6" above the Dam.. Due to the camera's greater height and sharper angle, we found reading the rulers more difficult.
On April 18, 2023, we relocated the camera to its current position below the boards that provide access across the opening of the Dam. This location, shown above, is close to the water level and provides a very clear ability to read the rulers. On June 26th we made a minor tweak to the camera mounting bracket.
