Straummålaren blei programmert til å måle straum kvart minutt. Den i gjennomsnittlige straumen var sterk i heile vassøyla. Den sterkaste straumen blei målt ved meters djup og var 2, cm/s. Dette tilsvarer ein Vc ( års repetisjonsperiode) på, m/s. Ved meters djup var straumen dominert av tidevatnet og ein sør gåande vinddriven straum. Ved, og meters djup var straumen kun dominert av tidevatnet. Lokaliteten er utsett for vinddriven overflatestraum frå nord/nordvest, nord, nordaust, aust og søraust. I måleperioden er det kun målt ein markert straumtopp i retning sør/søraust, sør, sør/sørvest og i nord/nordvest. Hovud straumretninga i heile vassøyla går i retning nord/nordvest og sør/søraust. Den sør/søraustlege straumretninga dominerte i måleperioden. Underskrift forfatter Frode Berge-Haveland Cand. Scient.
