Welcome To Rainbow Creek!
In just a few days things have changed around here due to the extreme heat (over 100) and no rain. The trees that were holding on at the end of July are now in serious trouble and beginning to die. This part of Texas has been experiencing drought for several years now with no relief in sight. Your infostudy tonight is on drought.

Drought
From Wikipedia, the free encyclopedia
Drought is an extended period when a region notes a deficiency in its water supply whether surface or underground water. A drought can last for months or years, or may be declared after as few as 15 days.[1] Generally, this occurs when a region receives consistently below average precipitation. It can have a substantial impact on the ecosystem and agriculture of the affected region. Although droughts can persist for several years, even a short, intense drought can cause significant damage[2] and harm the localeconomy.[3]
Many plant species, such as cacti, have adaptations such as reduced leaf area and waxy cuticles to enhance their ability to tolerate drought. Some others survive dry periods as buried seeds. Semi-permanent drought produces arid biomes such as deserts and grasslands. [4] Most arid ecosystems have inherently low productivity.
This global phenomenon has a widespread impact on agriculture. Lengthy periods of drought have long been a key trigger for mass migration and played a key role in a number of ongoing migrations and other humanitarian crises in the Horn of Africa and the Sahel.
According to F. Bagouls and Henri Gaussen's definition, a month is dry when the mean monthly precipitation in millimeters is equal to or lower than twice the mean monthly temperature in °C.
Consequences
Periods of droughts can have significant environmental, agricultural, health, economic and social consequences. The effect varies according to vulnerability. For example, subsistence farmers are more likely to migrate during drought because they do not have alternative food sources. Areas with populations that depend on as a major food source are more vulnerable to famine.
Drought can also reduce water quality, because lower water flows reduce dilution of pollutants and increase contamination of remaining water sources. Common consequences of drought include:
- Diminished crop growth or yield productions and carrying capacity for livestock
- Dust bowls, themselves a sign of erosion, which further erode the landscape
- Dust storms, when drought hits an area suffering from desertification and erosion
- Famine due to lack of water for irrigation
- Habitat damage, affecting both terrestrial and aquatic wildlife[5]
- Hunger, drought provides too little water to support food crops.
- Malnutrition, dehydration and related diseases
- Mass migration, resulting in internal displacement and international refugees
- Reduced electricity production due to reduced water flow through hydroelectric dams[6]
- Shortages of water for industrial users[7][8]
- Snake migration and increases in snakebites[9]
- Social unrest
- War over natural resources, including water and food
- Wildfires, such as Australian bushfires, are more common during times of drought.[10]
These are the tops of my tall trees, the Post Oaks and Red Oaks (old growth).
They are shedding their leaves and dead branches are increasing.
This is Rainbow Creek, dried all the way across as Fat Sissy will show:
Look who is hiding on the creek! It is the Kite!
