Who knew! Well, John Watts knows, and he will explain it to us on April 2.

Service and Volunteer Opportunities

Monthly Work Sessions– One Saturday a month, 9:00 – 11:00 am: Check Website for Details, including dates and locations which may vary or change:

  • April 6, 2019 – Location is 1787 Holford. We will continue attacking invasive plants in the prairie and privet in the adjoining forest. Invasive plants are non-native species which grow aggressively and crowd out the native plants. Invasives don’t have the variety and multitude of predators to keep them in check. Come be a hero and champion for native plants. It is only two hours out of your day and it is amazing how much can be accomplished.

  • May 11, 2019 – Location is 1787 Holford. From 9 to 11, we will toil as usual, maintaining the prairie and forest. Then, at 11, we will gather at the picnic tables for a Bring Your Own Picnic. It is a fun way to end our year and start the summer break. Bring your own sack lunch and drink. (Sorry, no beer or alcohol allowed in the park.)

  • Having mentioned “summer break”, be aware that our Executive Committee is not only enthusiastic, but energetic. We might organize a work session or two in the summer just for the fun of it. Watch for the odd announcement from us.

  • Upcoming Dates: 2019 – Summer break, September (to be announced)

NEWS – Sanitary Sewer Overflow Impacts Spring Creek

The first information source is NBC 5News, published Wednesday, March 20, 2019, paraphrased by Barbara Baynham

A sewer overflow Tuesday morning, March 19, released untreated sewage into Spring Creek. It happened at about 11:30 a.m. at a construction site near North Garland Avenue and Arapahoe Road. According to the City of Garland, construction crews struck a manhole, damaging an 18-inch wastewater collection pipe. The pipe is part of the city of Garland’s wastewater collection system.

City of Garland crews worked through the day and into the night to fix the break and contain the spill which was caused by a large piece of concrete that had become lodged inside the pipe. Crews bypassed the broken pipe and continued repairs on Wednesday. At one point, about 20 gallons of untreated sewage flowed from the damaged pipeline every minute. The overflow was stopped shortly after 9:30 Tuesday night. Officials in Garland are monitoring the quality of water in Spring Creek.

It was worried that the spill would also impact the Lake Ray Hubbard reservoir. The leak occurred about 10 miles upstream from the lake. Personnel there were monitoring the situation. Garland also notified Texas Commission on Environmental Quality.

Update from Wes Kucera, City of Garland Managing Director of Water and Wastewater

Water samples were taken upstream and downstream of the overflow and were analyzed by our Health Department. The analytical results yielded slightly higher results for BOD, Ammonia, TSS and E. Coli downstream of the overflow, however Dissolved Oxygen levels were high and pH levels were normal as indicated by the Health Department samples. There were no fish kills with this event.

Since I know you are curious, according to Mr. Kucera, the BOD is a measure of Biochemical Oxygen Demand which is the amount of dissolved oxygen needed for microorganisms to oxidize organic matter. From a wastewater standpoint, we measure BOD in our influent (Raw Sewage) and effluent (Treated Wastewater) to determine plant efficiency at BOD removal. Typical raw sewage has a BOD of 100 – 500 mg/L, and treated effluent ranges from 2-10mg/L range.

The TSS is Total Suspended Solids which is a measurement of particles larger than 2 microns found suspended in the water. Typical raw sewage ranges from 100-300mg/L and treated effluent ranges from 3-15mg/L.


Thank you! to all the members that made the special effort to be a the March meeting so we would have a quorum of voters. With more than enough voters present, we elected our ongoing Executive Committee and approved the revised Society Bylaws.

And Finally…
