![]() In October, Mr. Virgil Evans, a Sandy Creek resident, died in Houston after a long battle with cancer. Mr. Evans was retired from the military and had moved to our community over a year ago. He was talkative, friendly, and he liked everyone. In return, he was well-liked by his neighbors and by everyone he met. He had a wonderful sense of humor even during the last days of his illness. Virgil was good with his hands in woodcrafting, and he made beautiful furniture of all sorts for his home and for others. He also collected pictures of ships, and the walls of his home were filled with his collection.

Our streams and greenbelts are the jewels of our community. We test our streams’ water quality to ensure the health of our fish, turtles, and other aquatic life, in addition to the health of our children and pets who play in and near the water. Training and supplies for this testing are provided by the Lower Colorado River Authority (LCRA) River Watch program. We run these tests monthly and report the results on the front page of this newsletter and also to the LCRA.
Dissolved oxygen measures the amount of oxygen in the water available to fish and other aquatic life. Many things affect dissolved oxygen, including temperature (colder water can hold more oxygen than warmer water). More important, organic material, such as leaf litter, grass clippings, sewage, or runoff from feedlots, needs a lot of oxygen for decomposing by bacteria. A sudden drop in dissolved oxygen can stress aquatic life to the point of death or movement elsewhere.
Nitrogen (nitrates) and phosphorus (phosphates) are needed by all life, but too much nitrogen or phosphorus in our streams can cause excess growth, or blooms, of algae or other aquatic plants. As the plants die and rot, they use up oxygen in the water and reduce the amount available for fish to breathe. Excess nitrogen and phosphorus in our streams would most likely come from inadequate septic systems, animal wastes, and fertilizers, so controlling runoff is very important. (Testing for fecal coliform bacteria is a better way to spot septic system leaks, and we hope to start testing for that this year.)
TDS measures the dissolved solids, or salts, in water. Aquatic life needs some salts, just as people need sodium and potassium (both salts) in our diets. However, too much salt, usually from pollution or street and building runoff, can be harmful to aquatic life, just as too much can be harmful to us. Too much salt interferes with a creature’s internal water balance, and can cause dehydration or even death.
pH measures the relative acidity of our stream water. The pH scale runs from 0 to 14, with 0 being most acid, 14 being most basic, and 7 being neutral. The pH in our streams is above 7, which means that the water is slightly basic rather than acidic—a result of our acid-neutralizing limestone soils. Water that becomes either too acidic or too basic is harmful to aquatic life, but many young fish and insects are particularly sensitive to a low pH (acidic).
Temperature is an important measurement because it is related to dissolved oxygen, and because it has a great impact on plants and animals, including how well they can resist stress from pollution or disease.
