San Jacinto County Lake Quality
Texas, 2 lakes, measured by TCEQ
San Jacinto County has 2 monitored lakes — a thin enough sample that one or two stressed lakes can move the county average noticeably. Use the per-lake pages below for what actually matters. The 2 monitored lakes in San Jacinto County carry whatever clarity, phosphorus, and chlorophyll-a readings TCEQ has published, shown as reported.
Most of the county's monitored lakes are shallow, under 50 feet, which means wind keeps the water column mixed all summer and sediment-bound phosphorus releases back into the surface layer whenever the bottom is disturbed.
