This document analyzes the water balance and its effect on tube well efficiency at Malgaon Lake in Maharashtra, India. It summarizes the following key points: - Malgaon Lake has a surface area of approximately 4,225 square meters and receives canal water from the northwest. It has an uneven shape and building borders the northeast corner. - Researchers conducted surveys to determine the lake's current volume and depth. They calculated its total volume is 3,108 cubic meters and water availability is 2,447,650 liters at a current depth of 10 feet. - Increasing the lake's depth by 20-40% would significantly increase its total capacity and storage volume. This would help address the
