Excessive rainfall this month has eliminated much of the drought across Texas, with some lakes jumping more than 30 feet in less than two weeks. Among the lakes witnessing a significant rise is Lake Buchanan, a popular reservoir in Central Texas.
Why It Matters
Texas has battled years of drought that have seen many of its popular reservoirs' water levels plunge to dangerously low levels. For example, in 2023, water levels at Lake Travis became so low they revealed previously hidden pecan groves and a concrete plant.
Lake Buchanan has seen similarly volatile water levels in recent years. A year ago, the levels were 73 percent full. As of the most recent measurements, levels were 99.8 percent full, according to Water Data for Texas, which is considered full capacity for the lake.

What to Know
Over Independence Day weekend, torrential rain battered Central Texas, prompting the swift and significant rise of area rivers that brought deadly floods throughout the region. More than 100 people died.
Nearly two weeks later, the water has worked its way into area lakes and reservoirs. Water levels at Lake Travis continue to rise, and Lake Buchanan was recently considered full when its levels hit 1,020 feet.
Although Lake Buchanan was considered full in 2019 when its levels hit 1,018 feet, the reservoir hasn't hit the 1,020-foot level since March 2005, KXAN reported.
The Lower Colorado River Authority (LCRA), which manages Lake Buchanan, opened the floodgates at Buchanan Dam to let out some of the water earlier this week.
"Unlike Lake Travis, Lake Buchanan has no room to store floodwaters after it is full. LCRA manages Lake Buchanan to a maximum level of 1,020 feet above mean sea level," an LCRA report on flood management said.
The floodgates were closed on Wednesday afternoon, an LCRA spokesperson told Newsweek.
"Floodwater from Lake Buchanan was sent downstream through the series of dams on the Highland Lakes to Lake Travis, the only lake on the Highland Lakes with room to store floodwaters," the spokesperson said. "Our short-term projections are that Lake Travis will rise up to 675 feet above mean sea level over the next several days. As of 3:40 pm Central Time today Lake Travis is at 673.79 ft msl, or 88% full."
What People Are Saying
An LCRA spokesperson previously told Newsweek: "We have seen similar relatively large increases in the history of Lake Travis, which is in Flash Flood Alley."
LCRA posted on X, formerly Twitter, earlier this week: "Floodgate operations from Lake Buchanan today. LCRA opened a total of four floodgates at Buchanan Dam on July 14 – the first floodgate operations there since May 2019. This coordinated response helps manage significant water inflows across the Highland Lakes system."
CBS Austin reporter Bettie Cross posted on X: "Lake Buchanan hasn't looked like this in 15 years. It's 100% full. The LCRA is preparing to open 2 floodgates this afternoon. It will be the first time the @LCRA has opened a floodgate at Buchanan Dam since 2019."
What Happens Next
Water levels at Texas lakes and reservoirs will change throughout the summer depending on heat, water usage, and if there's continued rainfall in the region.

Dragon Bravo Fire Map: Blaze Grows to 71,000 Acres
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The Dragon Bravo fire has grown by nearly 30,000 acres in the span of three days as record-low humidities create challenging conditions and decrease the containment firefighters have secured over the past three weeks the flames have been burning. Why It Matters A lightning strike ignited the Dragon Bravo fire in the Grand Canyon's North Rim on July 4. In the three weeks the fire has been burning, there have been no injuries or fatalities, although 100 structures in the North Rim have been destroyed, including the historic Grand Canyon Lodge. The fire prompted National Park Service (NPS) officials to close the North Rim entrance for the season. There have been 1,000 evacuees. At any one time, 1,000 firefighters are combatting the flames. What to Know As of the most recent update, the fire is at 71,000 acres in size and only 9 percent contained. On Sunday, the fire's size was 44,429 acres and it was 26 percent contained. A map shows the boundary for the Dragon Bravo Fire burning in the Grand Canyon's North Rim. A map shows the boundary for the Dragon Bravo Fire burning in the Grand Canyon's North Rim. Inciweb "Progress on the Dragon Bravo Fire is moving in the negative direction - the fire saw nearly 20,000 acres of growth overnight," KUTV2 News reporter Olivia Kelleher posted on X, formerly Twitter, on Tuesday. "The containment was downgraded from 26% to 13% and then again to 9% a few moments ago." Southwest Area Incident Management Team Public Information Officer Lisa Jennings told Newsweek that weather is posing the biggest challenge to firefighters. As historically dry conditions contribute to the fire's rapid growth, firefighters have been unable to keep up with containment. "With the huge amount of fire activity over the past several days, we have had to reduce our containment because of the growth of the fire," Jennings told Newsweek. "As the fire grows in size, we have not been able to increase our containment at the same pace the fire is growing." Jennings was unable to provide an estimate on when the fire might be completely contained. What People Are Saying Jennings told Newsweek: "This is the driest it has ever been for the month of July. It just keeps breaking those records day after day." The most recent fire update said: "The strategy for fighting this fire remains full suppression. Firefighter and public safety remain top priorities. Unpredictable fire behavior requires crews to remain aware of and quickly respond to changes in their situation. Firefighters will continue their operations on the fire's flanks to protect values at risk in the area. Efforts are being made to keep the fire away from State Route 67." What Happens Next Fire suppression efforts will continue. Some light rain showers were expected on Tuesday, but fire officials warned significant precipitation wasn't likely.

Water Supply Emergency Declared in Texas City
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The City of Kerrville, Texas, activated its water conservation plan starting at midnight on Tuesday after the region experienced deadly flooding this month that made its water plant inoperable. Heavy rain across west Texas left at least 130 people dead, including girls attending Camp Mystic along the Guadalupe River. The city cited flood damage at its water treatment facilities as a driving factor behind the new measures, which elevated water use protocols to Stage 4 Emergency status, the city said in a post on its official Facebook page Monday night. Stage 4 means there are "severe water conservation conditions" prompting the restrictions to address the emergency," the post said. Newsweek has reached out to the City of Kerrville via email Monday afternoon for more information. Why It Matters Flooding throughout Texas led to widespread infrastructure disruptions, causing unexpected water emergencies for residents and municipalities. Although excess rainfall might appear to relieve drought concerns, floodwaters often overwhelm treatment plants, damage vital infrastructure and contaminate water sources—leaving communities vulnerable to shortages and quality concerns. These developments highlight the challenges Texas faces in balancing water supply, infrastructure resilience and conservation amid increasingly erratic climate conditions. Severe thunderstorms prompt emergency flash flood warnings on the banks of the Guadalupe River during a search and recovery mission on July 13, 2025, in Kerrville, Texas. Severe thunderstorms prompt emergency flash flood warnings on the banks of the Guadalupe River during a search and recovery mission on July 13, 2025, in Kerrville, Texas. Photo byWhat To Know The City of Kerrville officially declared a Stage 4 Water Emergency Monday, restricting all non-essential water use following heavy flooding that impacted its drinking water system. "The plant remains inoperable due to the flooding to Nimitz Lake and its impact on the intake equipment, and other areas within," the alert said. City officials said that the flooding forced shutdowns and repairs at its water treatment plant, which serves thousands of residents and businesses in the area. Residents have been urged to immediately comply with severe usage limits, including a complete ban on outdoor irrigation, vehicle washing and refilling of swimming pools. In Stage 4, the use of automatic and hose-end sprinklers as well as soaker hoses is prohibited. While restrictions are in place and plant repairs on continuing, the city will use groundwater wells, according to the post. The water that has been treated and provided does not pose a danger. The restrictions are in place to ensure the supply remains available. Flooding often disrupts water treatment capabilities by overwhelming filtration systems, contaminating supplies with debris or runoff, and damaging essential infrastructure such as intake pumps or electrical systems. In Kerrville's case, river surges caused by the recent storms made normal operations unsafe and unsustainable, leading to a temporary but urgent reduction in treated water production. What People Are Saying City of Kerrville officials, in a Facebook post Monday: "On July 28, 2025, the city manager for the City of Kerrville, Texas declared a water supply emergency for the city's water system. Pursuant to this declaration, the city manager has determined that the Stage 4 — Severe water conservation conditions is the most appropriate water conservation stage to address this emergency. The city manager made this declaration following information received from the city's water utility as to the continuing inoperable status of the city's water treatment plant. The plant remains inoperable due to the flooding to Nimitz Lake and its impact on the intake equipment, and other areas within. The city's entry into Stage 4 takes effect immediately on Tuesday, July 29, 2025 at 12 a.m., and the city has provided notice in accordance with Section 110-99 of the city's Code of Ordinances. Be advised that in Stage 4, automatic and hose end sprinklers and soaker hoses are prohibited on all days/times. City staff will continue to rely on groundwater wells to meet current water usage demands while plant repairs are continuing. Despite the plant remaining inoperable and the emergency declaration, there are no concerns regarding the quality of the treated water being provided. The implementation of Stage 4 is solely a water management measure at this time to aid in prolonging our groundwater supply. Stage 4 measures are identified in the table below. Further information regarding plant repairs, water conservation, and enforcement will be provided in future press releases. For more information on Stage 4 measures, please visit the City of Kerrville website at or call (830) 257-8000 for general questions." What Happens Next City officials in Kerrville said they would continue to monitor flood recovery efforts and water treatment repairs closely, lifting the Stage 4 Emergency once normal capacity and water quality are restored. State and local leaders said that ongoing reviews of water infrastructure will inform future resilience investments. For now, residents in affected areas face continued restrictions, with updates to be posted via official city communication channels.

Map Shows 8 States Under Threat of Severe Storms
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Eight states in the Northern U.S. could see severe thunderstorms accompanied by hail and damaging winds on Tuesday. Why It Matters On Tuesday, National Weather Service (NWS) meteorologists were warning people across eight states that they faced the threat of thunderstorms on Tuesday afternoon. Although no thunderstorm warnings were in place as of around noon Eastern time on Tuesday, thunderstorms can develop rapidly and prompt urgent warnings to take shelter. Residents in the affected areas were urged to monitor their local weather forecasts and remain ready to take shelter should a storm develop. The dangerous weather comes a day after parts of the Northern Plains faced hurricane-force winds on Monday. NWS Storm Prediction Center meteorologist Andrew Lyons told Newsweek it is not uncommon for the Northern Plains to see severe weather this time of year. What to Know On Tuesday, the NWS posted a map and brief forecast about the impending storms on Facebook. "Today: Severe thunderstorms are expected from southern Montana into the central High Plains, and across much of Nebraska and western Iowa," the post said. "Areas of damaging winds will be possible, with hail most likely over western areas." Eight states are at a "slight" risk for storms, which means scattered severe storms are possible. An even more widespread area was under a "marginal" risk, which indicates severe storms will be localized and isolated. Severe storms have the greatest chance of occurring in parts of Montana, Wyoming, South Dakota, Nebraska, Colorado, Kansas, Iowa, and Missouri on Tuesday afternoon and into the evening. As of Tuesday around noon Eastern time, no states in the forecast area had a severe thunderstorm warning or watch in place. What People Are Saying NWS in a Tuesday morning forecast: "Shortwave energy interacting with anomalous moisture and instability along a surface front will produce afternoon/evening storms across portions of the Northern/Central Plains today. Storms initiating in eastern Montana are forecast to congeal into a mesoscale convective system and sweep across parts of the Dakotas, Wyoming, Nebraska and Iowa by Wednesday morning. Slight risks of excessive rainfall (at least 15% chance) and severe thunderstorms (level 2/5) are in effect for many of the aforementioned areas with damaging winds and hail possible." NWS Bismarck, North Dakota, said in a hazardous weather outlook: "A few thunderstorms are possible this afternoon and early evening. Severe weather is not anticipated." NWS Rapid City, South Dakota, said in a hazardous weather outlook: "There is a slight risk (level 2 of 5) of severe thunderstorms today, meaning that scattered severe storms are possible. Primary hazards include large hail and damaging winds." What Happens Next People in the affected areas are urged to monitor local weather alerts throughout the day. After the storms move through the Northern Plains, NWS meteorologists anticipate they could bring a slight risk of excessive rainfall to parts of the Midwest on Wednesday.
