River flow rates in Alba County are currently lower than usual, with the exception of the Mures River; due to last week’s torrential rains in the Apuseni Mountains, its flow rate is higher than normal for this time of year, according to information presented on Tuesday at a press conference by Valentin Dican, director of the Alba Water Management System (SGA).
“Regarding the hydrological situation and the effects of the drought on the county, I must mention that we are facing a significant decrease in flow rates across almost all watercourses in the county. From a hydrological standpoint, we are observing a gradual reduction in river surface runoff,” said the director of SGA Alba.
Valentin Dican pointed out that there are several major river basins in the county and that the situation must be analyzed separately for each basin, according to Agerpres.
Thus, the director of SGA Alba indicated that the Mures, the county’s main watercourse, was recording an above-normal flow rate on Tuesday.
“The flow rate recorded today on the Mures River at Alba Iulia is 28 cubic meters per second. The normal level is lower, 18.2 cubic meters per second. However, this [higher flow rate – Ed.] is the result of Friday’s rains in Arieseni. It is possible that the rate will be slightly lower starting tomorrow,” Dican explained.
He added that the flow rate of 28 cubic meters per second represents 41% of the multi-annual average flow rate.
At the Câmpeni gauging stations, the flow rate on the Aries River was 5 mł/s on Tuesday, representing 74% of the multi-annual average, while on the Târnave rivers at Mihalt, it was 5.22 mł/s, representing 28% of the multi-annual average.
“These figures represent the data recorded today at hydrometric stations and must be interpreted within the context of hydrological trends for this period. What does low flow actually mean? When we say a river has a low flow, it does not automatically mean the river has dried up; it means the water resource available in the riverbed is lower than normal,” stated the representative of SGA Alba.
Regarding the Mihoiesti reservoir, the only dam near Câmpeni managed by SGA Alba, Valentin Dican stated that, while the water level had indeed approached the minimum operating level, preventive measures were taken to avoid any issues. “Initially, since there was no cause for alarm, we ensured that the outflow from the dam matched the inflow,” the SGA Alba director noted.
Regarding the dams on the Sebes Valley, which are managed by Hidroelectrica, Valentin Dican stated that he had been informed that the Oasa dam has a fill level of 81%, the Tau dam 49%, the Obreji de Capâlna dam 69%, and the Petresti dam 88%.
