From the air, it's easy to see that gravity has prevailed as commercial and residential development -- with scant environmental safeguards -- around Lake Casa Blanca has dumped tons of eroded dirt and silt into the bowl of the lake. Agricultural land practices on the watershed have also contributed to the siltation of the lake.
Development near the lake has come in many forms over the last several decades, but none so fast and furious as that of the last decade which includes the road bed for Loop 20, the construction of Texas A& M International University, the Laredo International Airport, warehousing developments, the new multi-purpose arena, and housing developments.
On the watershed of the lake it is also possible to see that the flow of Chacon Creek has been altered, diverted, or stopped on private land.
