This Section of the Fatničko Polje Webpages exclusively details the permanent authigenic karst springs within the confines of the polje.

There are several permanent and intermittent karst springs within the polje area. Several small permanent karst springs (local term = IZVOR) arise on the north perimeter. They are authigenic (A-Type) karst springs and have little variation in flow or chemical profile throughout the year.
It should be noted that the intermittent, temporary or periodic karst springs, which usually originate via estavelles and give vast quantities of water when they flow during the winter and spring, are also situated on the north perimeter or elsewhere in the Upper Polje area. This type of karst spring is known locally as a VRELO and are allogenic (B-Type) karst springs, dealt with individually and elsewhere in the Fatničko Polje Webpages.
The difference in terminology reflects the functionality, hydrochemistry and magnitude in the difference of yield Q between the two.

IZVOR "KUKALJ"

3.1.    IZVOR "KUKALJ" :
[GPS Identifiers : 43° 01.57' N : 018° 19.50' E. (7. Sats)]

3.1.1.  Location :
This captured karst spring is situated at an elevation of 497m asl. (1632 feet) above the north perimeter of the main polje floor east of Donja Fatnica. It is located beside a single-track, un-metalled polje access road. The spring outlet is via pipework set a stone structure, which has integral cattle-watering troughs and a main collecting trough. The overflow descends down to the polje floor below. This feature is contained in the attached video sequence MPEG3.1.  below. A detailed questioning of a local inhabitant gave rise to much information about the feature and revealed other useful information about the area.

IZVOR "VELIKI JASTREBINJAK"

3.3.    IZVOR "VELIKI JASTREBINJAK" :
[GPS Identifiers : 49° 01' 26'' N : 018° 20' 10'' E. (6. Sats)]

3.3.1  Location :
This captured karst spring is situated at an elevation of 490m asl. (1608 feet) and is located above the perimeter of the main polje floor east of Donje Fatnica at the northern perimeter of the Upper Polje. It is the more westerly situated of the two "Jastrebinjak" Karst Springs and is located between Izvor "Kukalj" and Estavela "Obod".
The spring outlet is via pipework leading from a concrete collecting cistern in which are set access manholes. The overflow descends down to the polje floor below via a natural open streamway.
