Z imenom Logaščica označujemo vodotok, ki nima izvira, ampak nastane s sotočjem Reke in Črnega potoka, ki se nahaja v bližini starega jedra Gornjega Logatca. Črni potok ima več izvirov ter manjših in večjih pritokov. Eden od izvirov Reke se imenuje Grajski studenec, ki je zajezen ter opremljen z vodno črpalko. Tudi Reka ima več pritokov, ob enem od večjih se nahaja Erikov ribnik.
Logaščica dobiva vodo z dolomitnega zaledja, njeno porečje pa meri okrog 18,5 kvadratnih kilometrov. Njene vode se podzemeljsko stekajo v porečje Ljubljanice.
Na strugi je bil na Marekah zgrajen tudi bazen, ki pa je danes opuščen. Od Marek je voda speljana po umetnem kanalu do Cerkovskega mlina, kjer je bila tudi žaga.
Pod Sekirico je Logaščica povezana z Lokvijo, manjšim jezerom. Tu so v preteklosti po ustnem izročilu kopali glino in pozimi sekali led za ledenice.
Na Logaščici sta bili poleg Marek še dve kopališči prvo na Brodu in kopališče pri Furlanovem mlinu.
Ponor Logaščice se imenuje Jačka, tj. sklepni del 800 metrov dolge kanjonske slepe doline. Ta se konča z navpično steno, pod katero je več zamreženih požiralnikov, v katerih izginja voda v podzemlje. Ob nizki in srednji vodi ponori odvajajo vso vodo, ko pa se kraško podzemlje po dolgem deževju napolni, začne voda zastajati. Večje poplave so bile novembra 1935, avgusta 1963, septembra 1965, januarja 1979, zadnje hujše poplave pa so bile jeseni 2009.

Ob Logaščici je bilo postavljenih več gospodarskih objektov, ki do delovali na vodno energijo:
– Jerajev mlin in žaga Franca Nagodeta ob Črnem potoku (od leta 1993 žaga in mlin delujeta na lastni električni pogon s pomočjo vodne energije Črnega potoka);
– nekdanji Cerkovski mlin in žaga (mlin je deloval do leta 1948);
– vodna žaga Petra Grassija pod Sekirico;
– mlin Franca Mihelčiča na Brodu;
– vodna žaga in elektrarna Gabrijela Oblaka na Brodu;
– vodna žaga in mlin Gregorja Tršarja;
– destilarna;
– vodna žaga in mlin Ivana Furlana.
Ko je leta 1857 stekla železniška povezava med Dunajem in Trstom, je bila zgrajena postaja, kjer so dopolnjevali zalogo vode parnim lokomotivam. Vodo za ta namen so črpali kar iz Logaščice iz poglobljenega dela potoka (zbiralnika vode), ki ga ljudje imenujejo Trumba (ta del je služil tudi kot kopališče). Nad trumbo je bila zgrajena zidana stavba – “Pupenhaus” – z vgrajenimi parnimi črpalkami, ki so dvigale vodo. Voda je nato po cevovodu tekla do železniške postaje. Danes zgradba ne služi več svojemu namenu, a spominja na možnost izkoriščanja vodne energije.

The name Logaščica refers to a watercourse that does not have a source, but is formed by the confluence of the Reka and the Črni potok, which is located near the old core of Gornji Logatec. The Črni potok has several sources and smaller and larger tributaries. One of the sources of the Reka is called Grajski studenec, which is dammed and equipped with a water pump. The Reka also has several tributaries, with Erikov ribnik located next to one of the larger ones.
The Logaščica receives water from the dolomite hinterland, and its basin measures around 18.5 square kilometers. Its waters flow underground into the Ljubljanica basin.
A swimming pool was also built on the riverbed at Marek, but is now abandoned. From Marek, the water is led through an artificial canal to the Cerkovski mlin, where there was also a sawmill. Below Sekirica, the Logaščica is connected to Lokvija, a smaller lake. According to oral tradition, clay was mined here in the past and ice was cut for ice rinks in the winter.
In addition to Mareke, there were two other swimming pools on Logaščica, the first in Brod and the swimming pool at Furlanov mlin.
The Logaščica sinkhole is called Jačka, i.e. the final part of an 800-meter-long canyon-like blind valley. It ends with a vertical wall, under which there are several networked sinkholes, in which water disappears into the underground. At low and medium water levels, the sinkholes drain all the water, but when the karst underground fills up after long rains, the water begins to stagnate. Major floods occurred in November 1935, August 1963, September 1965, January 1979, and the last serious floods were in the fall of 2009.

Several commercial facilities were built along the Logaščica that operated on water energy:
– Jeraj's mill and sawmill of Franc Nagodet on the Črni potok stream (since 1993, the sawmill and mill have operated on their own electric drive using the water energy of the Črni potok stream);
– the former Cerkovski mill and sawmill (the mill operated until 1948); – Petar Grassi's water sawmill under Sekirico;
– Franc Mihelčič's mill in Brod;
– Gabriel Oblak's water sawmill and power plant in Brod;
– Gregor Tršar's water sawmill and mill;
– a distillery;
– Ivan Furlan's water sawmill and mill.
When the railway connection between Vienna and Trieste was opened in 1857, a station was built where the water supply for steam locomotives was replenished. Water for this purpose was pumped directly from Logaščica from a deepened part of the stream (water reservoir), which people call Trumba (this part also served as a swimming area). A brick building – the “Pupenhaus” – was built above the trumba with built-in steam pumps that lifted the water. The water then flowed through a pipeline to the railway station. Today, the building no longer serves its purpose, but it reminds us of the possibility of harnessing water energy.
