Galveston Bay Handouts

  1. 1. Fall 2008 Flowing Rivers and Healthy Bays: New Legislation Will Protect Water for the Environment What are ‘environmental flows’? Environmental flows are the amount of water necessary for a river, estuary or other freshwater system to maintain its health and productivity. Why this law is unique In Texas, like much of the West, the concept of leaving water for the environment has been controversial. Water left in a river to flow out into an estuary or the Gulf of Mexico was once commonly described as ‘wasted.’ Now we know better. USFWS The new law is one of the most comprehensive in the nation, as it will set environ- mental flow standards for every major river system in the state. The law sets up a The last flock of wild, mi- public process for soliciting input from scientists and stakeholders.

A new law creates a process to determine how Why it matters to wildlife much freshwater the bay needs to stay healthy. This new law will benefit rivers and streams throughout the state, but its impact may be most pronounced along the coast. Texas has seven major coastal estuaries, or bays, formed by freshwater from rivers mixing with the saltier water of the Gulf of Mexico. This mixture of salt and fresh water is vital for fish, shrimp, oysters, crabs and many species of birds. It is the en- gine behind the $2 billion coastal recreational and commercial fishing economy. The diversity of bird species found on the Texas coast is among the highest in the world. A birding destination near Matagorda Bay, for example, regularly tops the Audubon Society’s prestigious Christmas Bird Count. The endangered whooping crane, which winters along San Antonio Bay near the mouth of the Guadalupe and TPWD San Antonio rivers, illustrates the importance of adequate flows (photo).

  2. 2. Determining how much water is needed The new law establishes a process for determining how much water is needed and begins the process of securing the water for the environment. Each area of the state will have a team of stakeholders from diverse interest groups and a science team made up solely of technical experts. The science team will make recommendations for flow quantities based on what the best available science indicates the rivers and bays need. Then the stakeholder group will look at the science team recommendations and consider them in conjunction TPWD with water management policies to develop their own set of recommendations.

Most of Texas’ marine sportfish depend on the mix These standards will be the goals for the amount of flows in the river and into the of salt and fresh water associated bay system. The flow standards likely will use a building-block approach, found in estuaries for at with a minimum level of flows to be provided during droughts and additional flow least one part of their life- levels to be provided during wetter periods. cycle. Securing the water When adopting the flow standards, the state environmental commission will also “set-aside” some of the water that is not already spoken for by existing permits. In some river systems, however, there will be little water available for the environ- mental flow set-asides. In these cases, the stakeholder groups will make recommen- dations on how to make up the difference. This will likely include the dedication of urban return flows, incentives to use water more efficiently, and donations or volun- tary purchases of existing water rights.

  4. 4. THE PROCESS Interaction of Bay/Basin Stakeholder Groups & Bay/Basin Science Teams 1. The Bay/Basin Stakeholder Group establishes Bay/Basin Science Team. Science Team is made up of scientists and technical experts with knowledge of region-specific issues and of scientists and technical experts with experience in developing environmental flow recommendations. 2. Stakeholder Group makes arrangements with state agencies and academic institutions to provide technical support for Stakeholder Group and for Science Team. Technical support would consist of efforts like performing literature reviews, undertaking water availability calculations using state water availability models, and helping to compile available information for use by the Stakeholder Group and Science Team. However, technical support would NOT include responsibility for developing the actual recommendations, which will be undertaken collectively by the Science Team. 3. Neither technical support contractor nor Science Team will be expected to undertake new substantive studies. Best available science will be used based on existing studies. Recommendations from the Science Team should note critical uncertainties and should identify information gaps that need to be addressed through future studies to help inform adaptive management process. 4. Bay/Basin Science Team develops its recommendations for a flow regime that, based solely on best available science, would be adequate to protect a sound ecological environment and to maintain the productivity, extent, and persistence of key aquatic habitats in and along the affected water bodies. The Texas Environmental Flows Science Advisory Committee provides input, as appropriate. Because the Science Team would be meeting and working locally, Stakeholder Group will be able to observe process to help inform subsequent stakeholder decisions. 5. Stakeholder Group then develops their own set of recommendations by considering the science-based recommendations in conjunction with important water policy considerations. The resulting Stakeholder recommendations will include proposals for the extent to which recommended flows should be provided through set aside of unappropriated flow. 6. TCEQ receives science-only recommendations from Bay/Basin Science Team, and science and policy combined recommendations from Bay/Basin Stakeholder Group. TCEQ also receives input from Environmental Flows Advisory Group, agency staff, and interested members of the public. Having separate science-based recommendations ensures that policy tradeoffs are transparent and helps to ensure a better informed TCEQ rulemaking process. 7. TCEQ adopts rules establishing environmental flow standards for the bay/basin area based on these recommendations and input, taking both science and policy into account. These rules will include a set-aside of unappropriated flows.

The Bay/Basin Stakeholder Group establishes the Bay/Basin Expert By 03/01/08 By 12/1/08 Science Team. The Bay/Basin Expert Science Team uses best available science to develop its recommendations for an environmental flow regime to protect a sound ecological environment. The Team submits these 03/01/08 - 12/1/08 – 12/1/09 recommendations to the Bay/Basin Stakeholder Group (and to the 03/01/09 (one year) Environmental Flow Advisory Group and the Texas Commission on Environmental Quality) by 12/1/09. These recommendations are solely science-based. The Bay/Basin Stakeholder Group considers the Bay/Basin Expert Science Team’s recommended environmental flow regime, the associated 03/01/09 - 12/1/09 – 6/1/10 policy considerations, and strategies to meet the flow recommendations. 9/01/09 (six months) The Stakeholder Group submits its comments and recommendations to the Texas Commission on Environmental Quality by 6/1/10. These are a composite of science- and policy-based recommendations. The Bay/Basin Stakeholder Group, with assistance from the Bay/Basin Expert Science Team, prepares and submits a work plan to address After 9/01/09 After 6/1/10 adaptive management (periodic review of the bay/basin environmental flow analyses, regime recommendations, standards and strategies to meet those standards). The Texas Commission on Environmental Quality adopts the 6/1/10 - 6/1/11 By 9/01/10 environmental flow standards for the Sabine & Neches Rivers/Sabine (one year) Lake Bay area. * At the 7/08 meeting of the Environmental Flows Advisory Group, the group adopted a revised schedule to the process—a 9 month slide to the dates and timeframes listed in Senate Bill 3. Last updated October, 2008
  6. 6. Environmental Flows Allocation Process Timeline Definitions Senate Bill 3 and House Bill 3 SB3 and HB3 were passed by the 80th Texas Legislature and took effect September 1, 2007. Article 1 of SB3 and HB3 addresses Environmental Flows, creating the Environmental Flows Allocation Process. For bill text: or Environmental Flows Allocation Process The Environmental Flows Allocation Process was created by the 80th Texas Legislature’s passage of Senate Bill 3 and House Bill 3 in 2007. This process will address two key components: a) how much water needs to flow in Texas rivers and into bays to maintain a sound ecological environment, and b) how to ensure that much flow is protected. Environmental Flows Advisory Group (EFAG) This group creates the Texas Environmental Flows Science Advisory Group and the eleven Bay/Basin Stakeholder Groups. In addition to interacting with these groups, the EFAG may make comments to TCEQ about the various flows recommendations. They also define the geographic boundaries of the bay/basin areas. This is a nine member group made up of three TX senators, three TX house members, one TCEQ commissioner, one Texas Water Development Board board member, and one Texas Parks and Wildlife Commissioner. Members were appointed by the governor, lt. governor and speaker of the house. See: and/or Texas Environmental Flows Science Advisory Committee This Committee provides science-based recommendations to state agency staff regarding ongoing studies and, through a liaison member, works with Bay/Basin Expert Science Teams to ensure consistent application of scientific principles. This is a nine member committee appointed by the Environmental Flows Advisory Group. See: Geographical extent of the river basins/bay system area Environmental Flows Advisory Group is to define the geographical extend of each river basin/bay system area in the state for the purpose of the Environmental Flows Allocation Process. Bay/Basin map boundaries were adopted at the 7/08 EFAG meeting. See map: Environmental Flow Regime This is a schedule of flow quantities that reflects seasonal and yearly fluctuations that typically would vary geographically, by specific location in a watershed, and that are shown to be adequate to support a sound ecological environment and maintain the productivity, extent, and persistence of key aquatic habitats in and along the affected water bodies. Bay/Basin Stakeholder Group Seventeen stakeholder categories will be represented by the citizens on this group, each with an interest in environmental flows in their designated bay/basin area. The Stakeholder Group provides flows recommendations, based on considerations of both science and policy, directly to TCEQ and also to the Environmental Flows Advisory Group. For more about these Groups or to sign up to get involved, see For information on the activities of the two stakeholder groups that are up and running (Sabine and Trinity) see: Bay/Basin Expert Science Team This team works with technical support from state agencies and academic institutions to develop environmental flows regime recommendations based solely on the best available science. Recommendations are presented to Bay/Basin Stakeholder Group, Environmental Flows Advisory Group, and TCEQ. These recommendations will be the first building block the Stakeholder Group uses in coming up with its environmental flow recommendations that will consider both science and policy. For more details about these Science Teams or to sign up to get involved, see Texas Commission on Environmental Quality The state agency responsible for developing the legal environmental flow standards and set-asides for each Bay/Basin area through a public rule-making process at the end of that area’s Environmental Flows Allocation Process. Adaptive Management Adaptive management is a structured, iterative process of decision-making in the face of uncertainty, with the goal of reducing uncertainty over time through systems monitoring. This approach embraces flexibility and adaptation.

  8. 8. SIMPLE WATER CONSERVATION TIPS TYPICAL HOME WATER USE* CLOTHES WASHER The single best thing you can do to improve clothes washer efficiency is to replace an old inefficient machine with a new high efficiency washer. In addition, you can: ♦ Use the shortest wash cycle for lightly soiled loads. ♦ Pretreat stains to avoid rewashing. ♦ If your washer has a variable water volume setting, select the minimum amount required per load. ♦ Operate the washer with full loads only – even if the machine has an adjustable load setting. Source: TWDB, A Homeowners Guide to Water Use and Conservation (1990) *These percentages can vary considerably depending on season, yard composition, irrigation system type, geographic region, installation of water efficient appliances and plumbing fixtures, and individual habits. The following list includes some simple ways to curb your water use around the house: indoors and outdoors. INDOOR WATER USES: BATHTUB/SHOWER ♦ Make sure that you have installed a water- efficient showerhead in all of your bathrooms. ♦ Take shorter showers. ♦ Turn off the water while soaping up or shampooing. ♦ Only fill the bathtub to a maximum of six inches (bathing small children and pets requires much less water). ♦ Make sure that your bathtub drain plug doesn’t leak.

  9. 9. OUTDOOR WATER USES: USING THE HOSE ♦ Rake and sweep leaves -- don't hose them away Consider installing a rainwater harvesting system; (using the hose to wash down sidewalks, driveways, it can be an easy, effective way to save water and pavements is a wasteful and unnecessary outdoors. Check with your local water provider to practice). see if they offer rebates on rainwater harvesting barrels and larger systems. For activities that require using a hose: ♦ Fill a bucket with water for washing your car at SPRINKLERS home. ♦ Avoid oscillating sprinklers and sprinkler heads ♦ Use a spray nozzle with a cutoff handle on your hose that produce mists or fine sprays (they result in so water doesn't flow continuously. evaporation losses). Drip systems or soaker hoses are most efficient. ♦ Use buckets rather than a hose or automatic system to water small gardens, flowers, plants, and shrubs so you have more control over where the water goes. ♦ Only water your yard and garden. Concrete sidewalks and gutters don't grow! ♦ Adjust your irrigation controller at least once a month to account for changes in the weather. ♦ Request an irrigation system audit from your local utility (many water providers offer this as a free service and it’s a great way to learn how you can more efficiently operate your sprinkler system). ♦ Less frequent, longer irrigation cycles can promote deep percolation. Also, install a rain shut-off valve to avoid unnecessary watering. ♦ Only water your landscape before sun-up or after sun-down to reduce evaporation losses. Train your lawn: ♦ Mow as infrequently as possible, and when you do mow, set the mower on its highest setting. Cutting the grass too short causes stress, forcing the roots to work harder and use more water. ♦ By spreading out your watering you can help your lawn to establish deeper roots that will help it survive drought periods.
