FLOODING IN THE JEZERO REGION AT NJIVICE ON KRK ISLAND

Official data published on the Web pages of the municipal
service company “Ponikve” (www.ponikve.hr/godisnje-kolicine-oborina)
concerning the amount of precipitation measured from 1964 to 2014 at the
source of Ponikve Lake show that the month of July, with an average of
46.50 lit/m2 of precipitation, is the driest month of the year. Data also
show that 135 lit/m2 of precipitation was measured in July of this year,
making it the rainiest July in the last 51 years. This is one of the main
causes of the extremely high water levels at lakes Ponikve and Jezero
and the flooded meadows at Mali Lug and Veliki Lug. It is difficult to
predict what effect this extremely wet summer will have on plant and animal
life. What we know for sure, is that these practically tropical conditions
are suited to animals that spend at least a part of their life cycle in
water, for example, mosquitoes.

This year’s Bird-ringing Camp, organized for a number
of years now by the Association “Jezero” and Public Institution
“Priroda” at the Jezero Ornithological Station, is experiencing
difficulties. Namely, the high water level has made it impossible to set
up mist nets in the usual places and this is expected to affect the results
of bird-ringing.
