The ClimateBasis programme gathers and accumulates data describing the climatological and hydrological conditions in Kobbefjord. Two automatic climate stations (C1 and C2), two automatic hydrometric stations (H1 and H2) and three diver stations (H3, H4 and H5) measure data.

The two climate stations are placed next to each other to ensure data continuity. Sixteen climate parameters, including two derived parameters, are monitored, and data are stored in a database.

In Kobbefjord, measurements of the water level and discharge started in 2006 at H1, at H2, H3 and H4 in 2007 and at H5 in 2008. Manual measurements of discharge were in 2009 continued at H1, H3, H4 and H5. H1 and H2 are measuring throughout the year, while measurements at H3, H4 and H5 starts up in early spring when the rivers are free of snow and ice, and ends in late autumn before the river freeze.

In both 2007 and 2008, stage-discharge relations (Q/h-relation) were established for H1, but after the 2008 season there was still a lack of measurements at high water level. In 2009, measurements were made at high water levels and a new Q/h-relation was established. For H2, H3, H4 and H5 there are still a lack of discharge measurements to establish reliable Q/h-relations.

For H1, which is placed at the main river in Kobbefjord, the total discharge during 2009 was 39.2 million m3. The peak discharge in 2009 was recorded on 27 June and was caused by precipitation. In late September, a combination of snowmelt and precipitation resulted in a water level just one centimetre lower than the one recorded in June. During this event, five manual discharge measurements were carried out.
