Tarrant County Lake Quality
Texas, 6 lakes, measured by TCEQ
Tarrant County holds 6 monitored lakes. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. 2 of those lakes carry recent nutrient and algae readings. The county-level summary describes that subset, not every water body listed. Phosphorus and algae readings vary widely across Tarrant County; the per-lake pages below carry the numbers.
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. Grapevine Lake has the lowest nutrient and algae readings in the county.
