1. Cypress Creek at Jacobs Well (CRP/TST)

This site is at the perennial headwaters of Cypress Creek. The inflow of groundwater highly influences Jacob’s Well in terms of water chemistry. The creek continues upstream of Jacobs Well, but this section is usually dry unless there is precipitation. Jacobs Well is an artesian spring. The Well is approximately 3 – 4 m wide and about 13 m deep. At the bottom of Jacobs Well is an entrance to an underwater network of caves that enters into the Hays Trinity Aquifer. The spring flow of Jacobs Well is around 1 – 3 cubic feet per second and is the major source of water in Cypress Creek. The surrounding area contains limestone boulders, and the riparian vegetation consists of cypress, junipers and live oaks. Jacob’s Well is part of a nature preserve and interpretive center.

Monitoring samples at Jacob’s Well are taken off of the concrete ledge on the well side.

This site is also monitored by Texas Stream Team. Please visit their database for their info on this site's parameters.

*The purpose of this site is to monitor the Wimberley Wastewater Project. In times when irrigation cannot occur, and on-site effluent storage capacity is full, the effluent would be discharged into Deer Creek, which empties into the Blanco River, just downstream of the Ranch Road 12 Bridge. The City of Wimberley would be authorized to discharge up to 75,000 gallons per day. It is important to note that discharges would generally be associated with wet periods when irrigation couldn’t occur and when the flow in the river would be significantly higher. In such cases, effluent flows would be 0.07 percent of the flow of the Blanco River and significantly diluted by the increased river flows. On an annual basis, it is estimated that effluent discharges would represent less than 0.002 percent of the flow of the Blanco River. The TCEQ establishes discharge limits that protect human health and the aquatic environment. The City is committed to producing a superior quality effluent, one that is likely better than what would be required by the TCEQ. The City intends to provide a high level of treatment of its wastewater, including primary, secondary, tertiary treatment, phosphorus removal, and disinfection. With that said, it is City’s intent to seek TCEQ approval of an effluent limit of 5 milligrams per liter (mg/L) of Biochemical Oxygen Demand (BOD), 5 mg/L total suspended solids (TSS), 2 mg/L ammonia-nitrogen (NH3), and .5 mg/L total phosphorus (TP). The effluent will be disinfected and would have less than 126 E. Coli units per 100 milliliter (ml) – a bacteria level within the acceptable limits for contact water recreation. The quality of water in the Blanco River varies depending on weather and flow conditions. In wet periods, when effluent discharge would likely occur, the River will be carrying storm water. Typically, urban storm water has a BOD level of at least 8 mg/L, 170 mg/L TSS, 0.8 mg.L NH3, 0.5 mg/L TP, and 21,000 fecal coliform colonies per 100 ml while agricultural runoff would have a TSS of 2,270 mg/L, 11.9 mg/L total Nitrogen, and 3.7 mg/L TP. With this in mind, the effluent discharged from the proposed wastewater system will be significantly better, in terms of water quality and impact on the environment, than typical storm water runoff. Due to the high level of treatment, the infrequent occurrence of discharges, and the volume of discharges compared to the flow in the Blanco River, adverse impacts to the aquatic ecology or contact recreation in the Blanco River are not anticipated.
