1. Ruschist operation of Kakhovka HPP (K-HPP) dam has been reckless. Kakhovka Reservoir (KR) water level has alternated from record low to record high in just 3 months. Loop (6 FEB-6 MAY 2023) shows sand bars receding with rising KR water. #NAFOWeather🧵

2. These images are of the K-HPP from Left: 6 FEB, and Right: 6 MAY 2023 (enhanced from data included in loop).

3. North Crimean Canal intake, Left 20 FEB 2023 Right 6 May 2023: Latest image show water gushing through NCC intake gate at Tavrisk as record KR level is pushing water through gravity fed NCC at high rates.

4. Zaporizhzhia Nuclear Power (Z-NPP) Plant: More retreating sand bars west and north of Z-NPP cooling pond and "sprayer" canals. Left: 5 MAR 2023 Right: 6 MAY 2023

5. North KR Islands towards Dnipro. Sand bars have disappeared once again as KR water level rapidly increased at record pace from 14.0 meters to 17.0 meters in 3 months. Left: 2 MAR 2023 Right: 6 MAR 2023

6. Kakhovka Reservoir contains over 18 cubic kilometers of water, 46% of all water storage in the Dnipro cascade. Ruschist incompetence and/or intentional mismanagement continues to put thousands of Ukrainian civilians at risk. end/
