Water Level Watch
Water levels in Severn Sound are monitored on an hourly basis at the gauge in Midland Harbour
Water Level Gauge at Farlain Lake
Click on the image you can see on the left for instructions on reading the gauge. Volunteers are also asked to record weather conditions (sun/cloud), whether winds are onshore or offshore, and give an estimate of wave height (calm, ripple, small, medium, large). It’s best not to record water levels when waves are larger than approximately 15 cm (6 in). Volunteers can submit water level readings and photos of the gauge (to help verify observations) by email to firstname.lastname@example.org with “Farlain Lake water levels” in the title. Alternatively, you can use this form to record your data and submit it all at once at the end of the season.
Farlain Lake is unique in that it has no surface outflow, and therefore lake levels respond more drastically to climate factors. Collecting as many data points as possible will allow SSEA scientists to describe the variations in water levels over short and long time periods, and help to determine the causes of these variations, such as rainfall, particularly in the winter, and snowmelt timing. Predictions of future climate indicate an increased likelihood of longer periods of drought followed by more intense storm events, and increased rainfall in the winter months. These changes can lead to wider swings in water levels. Determining patterns in water levels on Farlain Lake will assist shoreline residents in understanding impacts of climate change on the lake, and will help inform appropriate adaptive measures.
