The Quebrada de Ullúm Dam, or simply Ullúm Dam, is an embankment dam on the San Juan River, just west of San Juan in Ullúm Department of the Province of San Juan, Argentina. It is located at the gorge of the Quebrada de Ullum, 18 kilometres (11 mi) upstream from the provincial capital San Juan, and creates a reservoir with an area of 32 square kilometres (12 sq mi), a volume of 440 million cubic metres (16×10^⁹ cu ft), and average and maximum depths of 15 and 40 metres (49 and 131 ft), respectively. The reservoir feeds a hydroelectric power station with an installed power capacity of 45 megawatts (60,000 hp).

The region is arid, with mean annual rainfall below 85 millimetres (3.3 in), and is traversed by the rivers, San Juan and Jáchal. The dam is employed to regulate the flow to irrigate about 800 square kilometres (310 sq mi) of the Tulum Valley for agriculture, which is the basis of the economy of San Juan. It also allows for recreational and tourist activities.

In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. They were thought to have appeared as early as the mid-late Ordovician period as an adaptation of early land plants.

Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula.

In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. In some rare cases, diploid spore is also produced in some algae, or fungi. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote, which develops into a new sporophyte. This cycle is known as alternation of generations.
