Bogati sedimenti šljunka i pijeska u nizini Drave, pa tako i u Podravini oko Šoderice, nastali su fluvijalnom erozijom na prijelazu iz pleistocena u holocen. Ponegdje su naslage debele i više od 200 metara, a dubina slojeva zavisi i o recentnim tektonskim gibanjima. Geomorfološki se krajolik područja Šoderice stalno oblikuje tijekom holocena, a pogotovo meandriranjem Drave. U članku je još prikazana procjena zaliha šljunka i pijeska, zatim temeljito povijesno-ekološki pregled eksploatacije šljunka i pijeska od 1868. do danas, te ekološke prilike i turistička valorizacija jezera Šoderica., Rich sediments of sand and gravel in the valley of Drava River, including Podravina region nearby Lake Šoderica, were accumulated by fluvial erosion in the late Pleistocene and early Holocene. In some places, these deposits are over 200 meters thick, and the depth of layers depends on the recent tectonic movements. Geomorphologic landscape of the area of Lake Šoderica had been forming during the Holocene, especially by meandering of Drava river. The paper provides an assessment of sand and gravel deposits, a thorough historical-ecological review of gravel/sand exploitation in the period from 1868 to the present day, as well as well as the environmental opportunities and tourism valorization of Lake Šoderica.
