Interpretation of  River Level Data

The graphs show the change in river level over the last two to three days. An increase in river level is normally associated with rainfall in the catchment, however certain sites are subject to artificial control by, for instance, hydro power stations that may artificially influence the level of the river (see the Glass at Kerrow Wood). SEPA use level data to calculate the river flow since the direct measurement of flow is difficult and expensive.

The graphs show the river level relative to a local datum and may not directly represent the depth of water. To give the user some perspective on the relative level of the river a 'base level' has been given for each site. The base level represents a typical summer level in the river and has been calculated as the level that is exceeded for 95% of the time (95 percentile). The level will be below this for approximately 18 days in an average year. At some sites this figure is not available.
