Time To Celebrate: Lake Travis Is Full And The Current Drought Is Officially Over




Yesterday, the water level of Lake Travis rose above 681 feet above mean sea level (msl) for the first time since the fall of 2007, after dropping below 630 feet msl in late September of last year. The El Nino weather pattern is what normally brings Texas out of its recurring historical droughts, and the El Nino of the last 6 months was no exception, raising the level of Lake Travis over 51 feet since its lowest water level during the current drought.

The full pool of the lake, and the end of the drought, is great news and certainly cause for celebration in the Texas Hill Country. Last summer, the low lake level closed most, if not all, of the lake’s public boat ramps. This had a negative financial impact on businesses along the lake, including marinas, waterfront restaurants, music venues, hotels, and tourist rental properties. Equally bad, “sometimes islands” appeared on the lake, causing accidents and injuries, especially among boaters unfamiliar with the lake. And, residents across the hill country, dealt with the watering restrictions common in times of drought.

This year will be much different. Currently, the lake level is 10 feet above what the level would normally be during a typical March. Businesses along all of the Highland Lakes, including Lake Travis, will no doubt thrive this year, but, then again, this is Texas, the land of feast or famine. Texans in the hill country have learned how to adapt to fast changing weather and climate over the years. One year’s prosperity might bring something quite different the next year. We’ve seen it all before, and, many times.

But, given the current conditions, it is time to celebrate the “feast” of a full lake and the end of the current drought. I will enjoy it while I can, because Texas weather history tells me, it won’t last forever.

The Only Thing Predictable About Texas Weather Is Its Unpredictability




This past year has given the folks living in the Texas Hill Country quite a ride with respect to weather. During 2009, the area experienced a severe drought, 68 days at or above 100 degrees, and some of the lowest water levels on Lake Travis ever. Then, last fall, the rains started, followed by a dusting of snow in December. January of this year, along with a lot of places in the South, brought a couple of nights of unbelievably cold temperatures which turned many of the palm fronds in and around the hill country the color of brown cardboard.

This past Sunday, it was in the 70’s, and yesterday, just a bit cooler. The days were perfect for golfing and boating, and on both days golfers and boaters were out in force. Today, however, the bottom dropped out. It rained early this morning, followed by a little snow, then sleet, and then a complete changeover to all snow for most of the day. While there were no golfers or boaters out today, children around the area, who rarely if ever see measurable snow, were having lots of fun. The falling snow covered flowers, grass, and trees.

The weather in the hill country this past year was unusual, but only because of its extremes. The area usually enjoys a semi-tropical climate with sunny days, hot summers, and mild winters. Precipitation is normally spread evenly throughout the year, with the wettest months being in May and October. What made this past year a little different was the higher than normal numbers of extremely hot days, the lack of rain, the very bitter cold snap, lower than average temperatures during this winter, and measurable snow. And, while this does not happen in most years, it has all happened before, and many times. This is Texas, after all.

The hill country is used to “feast or famine” weather, and it gives rise to the old expression down here, “if you don’t like the weather, wait a minute.” Since before recorded time, inhabitants of the region have been accustomed to what is now called a “Blue Norther.” In the fall, cold fronts can come in fast, and temperatures can often drop 20 or 40 degrees, or even more, in a matter of minutes.

I’m not big fan of the cold, snow, or winter weather, which is one of the reasons I moved to the hill country after living all my life up North. Nevertheless, I did enjoy the nostalgic novelty of the snow today. Tomorrow it is forecasted to be in the upper 50’s, and later in the week, back into the middle to upper 60’s.

The only thing predictable about Texas weather, I guess, is its unpredictability.

This Past Week: The Texas Chill Country



Like most of the rest of the country this past week, the temperatures in the Texas Hill Country have been brutal. As temperatures dropped to well below 20°F for a few nights last week, those in this area who claim to know say it’s been the coldest spell in about fifteen years. And, while 20°F in January may not seem too bad for someone living in Minot, North Dakota, it is around here.

Winter weather in the hill country brings on its own set of unique behaviors among the folks who live here. During a normal winter, when the weather cools, residents perform what is known as the “Hill Country Shuffle.” On those relatively few nights when the temperature comes close to or dips below freezing, folks will shuffle their potted tropical plants inside the house for the night. The next day, with the rising sun, the plants are then shuffled back outside. On the coldest nights during a typical winter, it is not uncommon to see bed sheets thrown over the more delicate plants in gardens and yards.

This past week, however, as an unusually strong arctic chill settled in, extreme measures were needed as people sought to protect their landscapes and the significant investments made in their plants. Along with the so-called “shuffle,” the covering of plants with sheets and freeze blankets, many homeowners and businesses were also wrapping the trunks of smaller palm trees with burlap or other material, and mulching the base of the trees.

Following this cold snap, most of the palms I’ve seen (at least around where I live) appear to have come through the week reasonably well, although, I have seen slight bronzing of the fronds on some of the trees. The exception to this observation is for those trees which never should have been planted around here in the first place.

In our area, we can successfully grow about nine different types of palms, which include, California Fan Palms, Canary Island Date Palms, Date Palms, Mediterranean Fan Palms, Mexican Fan Palms, Pindo Palms, Texas Sabal Palms, Windmill Palms, and Queen Palms. In terms of Cycads, Sago Palms are also abundant. In some rare cases, with the right protection, other palms can be grown. Personally, I’ve had success with Miniature Date Palm Trees, which technically should not grow very well in this area. However, since I grow them right next to the warm house, the micro-climate probably accounts for their survival.

Even in the warmest of winters, there are some types of palms (like Bottle Palms and King Palms) which never make it through. The obvious reason is that they are far too delicate for even for our usually mild winters. And despite this fact, I see people planting them year after year with the same result, very dead trees. Part of the problem lies in the fact that local retailers continue to sell trees which are clearly inappropriate for our climate. Bottle Palms and King Palms will never survive a hill country winter, and the dead trees look awful.

The weather is supposed to warm up this week. This means that the plants inside the house will be shuffled back to the porches, decks, and balconies outside. In the yards and gardens, the sheets, freeze blankets, and trunk wrappings will all be removed from the plants and trees and shuffled back into the house. And, at least for the time being, another “Hill Country Shuffle” has concluded and the Texas Chill Country can once again return to being the Texas Hill Country.
