Your aquatic ecosystem is showing signs of premature aging. The physical and biological indicators are mounting:
- Decrease in Bathymetry: The effective water column is visibly shrinking. The lake bottom is rising each year, reducing the storage volume.
- Degraded Sedimentary Facies: An accumulation of black, fluid (unconsolidated) mud that releases gas at the slightest disturbance.
- Thermal Changes: Water warms up faster and earlier in the season, promoting evaporation and the concentration of pollutants.
- Centripetal Plant Colonization: Riparian plants (helophytes) and submerged plants (hydrophytes such as water primrose or water milfoil) are spreading toward the center of the body of water.
- Organic Turbidity: The water loses its clarity, becoming clouded with fine particles that no longer settle.
