The most obvious sign of a leaking irrigation pond is a pattern of significant and consistent drops in the pond's water level that cannot be attributed to normal factors like evaporation or planned water usage. Look out for areas around the pond that have consistently damp or saturated soil, even during dry weather, as these spots may signify water seepage.
Unusual growth of vegetation, particularly aquatic plants, in specific areas of the pond may suggest a leak, as leaks can provide constant moisture and nutrients. Sudden shifts in water quality, such as increased turbidity, sedimentation, or variations in temperature, may be associated with a leak, which can affect the pond's ecosystem. A sudden proliferation of algae, particularly near the water's surface, can indirectly suggest a leak, as excess nutrients from leaks can promote algae growth.
