Suvga bo'lgan loyiha talabi Oddiy sharoitlarda loyiha 0,37 m3/s (1324 m3/s) dan ajralib chiqadi; Janubiy Mirzacho'l kanali
oqimining juda kichik qismi (quyidagi jadvalga qarang). "Haddan tashqari eng yomon holatda"
kam drenaj holatlari (kamdan-kam hollarda va Janubiy Mirzacho'l kanali operatorlari
tomonidan, masalan, texnik xizmat ko'rsatish yoki suvga bo'lgan ehtiyojni kamaytirish kabi
maqsadli drenajlash bilan bog'liq bo'lishi mumkin), loyiha bo'yicha suv olish mavjud bo'lgan
oqimning <10% bo'lib qoladi.

Based on data obtained from historic Uzhydromet station gauge records,
the extreme minimum flows
indicated in the table (above) were mainly observed in the 1970-80s, whereas for the past 20 years, monthly minimum
water discharge has not fallen below 5m3/s. It is also noted that: (a) the occurrence off canal flows <5m3/s tend to
occur in November and December – possibly due to the absence of irrigation demand during this period; and (b) the
