Hourly adult ladder water temperatures are graphed from April 1 through
This line graph compares the hourly ladder water temperatures for the entrance monitor, exit monitor and monitors located midway through the ladder. It plots the difference between neighboring monitor temperatures on bar graphs below the temperature graphs.
The data on these pages are from the Army Corps of Engineers' Hobo Water Temperature Monitors. The data is sent weekly to the FPC, uploaded into a database, used to create the graphs and tables on the result webpages and are available for download on a csv link below each graph.
