Water level data for Arboleda Stream at La Selva Research Station, Costa Rica

Water level data for Arboleda Stream at La Selva Research Station, Costa Rica Stream water level (m) was measured in Arboleda stream, a tributary of the Sura, in the stilling pool behind a 120° sharp-crested V-notch weir. Water level was recorded every 15 min with an Enviro-Systems shaft encoder (pulley–float–counterweight mechanism) connected to a Campbell Scientific datalogger (Genereux et al. 2005). This system does not require correction for atmospheric pressure. A secondary system was added to the weir in 2018. Two pressure transducers (Onset HOBO U20L-04) one submerged to record water pressure and the other placed above the water surface to correct for atmospheric pressure. Water level was recorded at 15-minute intervals. Columnsdate: year, month, dayLevel (m): Average daily water level at the weir in metersSource: Data source used.
