 Peak Levels for the River Thames at Osney and Godstow Locks          
            
 Notes:          
 Level data digitised from the original lockeepers records.          
 All levels quoted in Metres above Ordnance Datum.          
 Data was extracted from the paper records when levels exceed a 'typical low flood level'. Typical low flood levels are unique at each weir and roughly equate to bankfull level. They were set based on levels on the 1st and 22nd of December 1952, but some have since been modified to ensure a consistent number of events were selected at each site  
 Dates represent the start of a period of high levels not neceserily the exact date of the highest levels.          
 Data has not been extensively checked. Anomalies may be present in this dataset.  
 Levels are converted from feet and inches to metric units, and ranked according to level.          
 Measurements are manually taken by the lockeeper on the upstream (head water) and downstream (tail water) sides of the locks on the River Thames, 4-5 times per day during daylight hours.  
 Full records for all locks on the River Thames are held by the Environment Agency. The records date back to the late 19th century but the data has not been digitised except for periods of high flow as outlined above..
