Texas lake retirement markets: water levels, flood and drought exposure, and private versus public lakes

Summary

Most Texas lakes are reservoirs. They were built to store water for cities, farms and industry or to hold back floods, and recreation and shoreline homes came afterward. That origin shapes a retirement purchase. The level of the lake is set by an operator with other duties, so a view that looks permanent in a wet autumn can look different after a dry summer, and the same operator may be the one that decides whether a dock is allowed. This guide looks at the lake markets for which published place and community pages exist: the Highland Lakes towns of Horseshoe Bay, Marble Falls, Llano and Lakeway, Lake Granbury at Granbury, Cedar Creek Lake at Gun Barrel City, Lake Conroe at Conroe and Willis, Lake Ray Hubbard at Rockwall, Lake Lewisville at Frisco Lakes, and the club-owned lakes of Hide-A-Way Lake.

The guide leans on the agencies that run the lakes: the Lower Colorado River Authority (LCRA), the Brazos River Authority, the Tarrant Regional Water District (TRWD), the San Jacinto River Authority and the Texas Water Development Board (TWDB). Each publishes different information, so the comparison is by type of lake and type of risk, not a ranking. Hospital distances appear only as hospitals, cities and local agencies describe them, and no drive times are invented. Canyon Lake, the reservoir behind the Guadalupe River above New Braunfels, is not covered as a market because no place page treats it as one.

Dates matter on a lake, so each level and status below carries the date of the page that reports it. Lake levels, floodgate operations and watering stages change daily or weekly, and the figures here are a snapshot from early October 2026 intended to show how the systems work, not to predict next year. For drought, heat and wildfire beyond the shoreline, see the guide to hail, wildfire, drought, heat and power outages.

Key takeaways

• The operator and purpose of a lake explain its behavior: Lake Travis is a water-supply and flood-storage lake designed to rise and fall, while Inks, LBJ and Marble Falls are pass-through lakes that LCRA says typically operate within about a foot and can rise well above that in floods.
• Levels are snapshots. LCRA reported Lake Buchanan at 1018.56 feet and Lake Travis at 678.05 feet on October 8, 2026, with the two supply lakes about 96 percent full, while the TWDB drought map for October 6, 2026 showed 82.00 percent of Texas in moderate drought or worse. Lake Conroe's recorded range runs from 192.68 feet to 206.24 feet.
• Lake rules differ by authority. Lake Granbury docks carry a one-time $75 permit and inspection fee under the BRA, drought stages follow combined storage in three lakes, and Hide-A-Way Lake's private lakes follow the club's registration and wake rules, not the state's rules for public waters.
• Hospital access varies more than the lake does. Horseshoe Bay residents look to Marble Falls and Burnet, Marble Falls, Lakeway, Granbury, Conroe and Rockwall have hospitals in the city, and Gun Barrel City's economic development corporation places UT Health Athens 24 miles away. Check network coverage and the facility type before choosing a shoreline.
• Vacancy is a signal of second-home use: the Census Bureau estimates 39.5 percent of housing units in Horseshoe Bay are vacant, against 10.3 percent in Lakeway. Flood coverage is separate from homeowners insurance, and FEMA and local officials, not the lake operator, designate floodplains.

Three kinds of lake: supply, flood storage and pass-through

The LCRA's description of the Highland Lakes is the clearest statement of why lakes differ. The Colorado River flows through an area LCRA calls Flash Flood Alley, which it says has one of the greatest risks for flash floods in the United States because of steep terrain, shallow soil and unusually high rainfall rates. Lake Buchanan and Lake Travis are the region's water-supply reservoirs and were designed to fluctuate, rising while capturing water in rainy times and falling as water is used or evaporates. Lake Travis is the only one of the six Highland Lakes designed to store floodwaters. LCRA states that it is considered full for water supply at 681 feet above mean sea level and that its flood pool can hold an additional 33 feet, or 776,062 acre-feet, and that any area in the flood pool is subject to being inundated.

Lake Buchanan has no room to store floodwaters once it is full, and LCRA manages it to a maximum of 1,020 feet. The smaller lakes between Buchanan and Travis, Inks, LBJ and Marble Falls, are pass-through lakes. LCRA says these lakes have no capacity to store floodwaters, typically operate within a range of about a foot, and can rise well above that range during floods, with levels that vary even along the length of a lake. For a homeowner this is a practical difference. Because those lakes typically operate within about a foot, a dock on Lake LBJ or Lake Marble Falls generally faces a steadier water level than one on Lake Travis, though a flood can raise the pass-through lakes quickly. A dock on Lake Travis can be left far from the water in a drought and covered in a flood, because the lake is meant to move.

Other Texas lakes sort the same way. TRWD says Cedar Creek Lake has a conservation level, which it defines as the permitted level of water the district may hold, and that any amount above it is used for temporary storage of floodwaters and must be released downstream. The San Jacinto River Authority publishes a normal conservation level of 201 feet for Lake Conroe and a flowage easement at 207 feet, the area the lake can reach in a rainfall event. TWDB says Lake Ray Hubbard is owned by the City of Dallas and operated by Dallas Water Utilities for municipal and industrial water supply, flood control and recreation. The operator and the purpose are the first two facts to check for any lake.

The Highland Lakes: Horseshoe Bay, Marble Falls, Llano and Lakeway

The Highland Lakes towns share one operator and one set of rules but sit on different kinds of lake. Horseshoe Bay is on Lake LBJ, Marble Falls on Lake Marble Falls, and Lakeway on Lake Travis. Llano is not on a Highland Lakes reservoir; it sits on the Llano River, and LCRA's early-October updates describe floodgate operations at the Wirtz and Starcke dams to pass floodwaters from the Llano River downstream into Lake Travis. The region is described in more detail at Highland Lakes.

LCRA's lake-level page, fetched on October 8, 2026, shows Lake Buchanan at 1018.56 feet and Lake Travis at 678.05 feet, with the two supply lakes together holding about 1,908,161 acre-feet, or 96 percent. Against Lake Travis's 681-foot full level, our arithmetic puts the lake a little under three feet low that day. On July 1, 2026, LCRA reported combined storage of 1,834,024 acre-feet, about 92 percent, and a water-supply condition of Normal under its 2020 Water Management Plan, which also defines Less Severe Drought and Extraordinary Drought conditions that govern how much stored water goes to interruptible agricultural customers downstream. The rise from 92 to 96 percent came with the early-October rain described below, and it does not make the lakes immune to drought.

That rain also shows the flood side. LCRA's flood page, as of 10:00 pm on October 3, 2026, said LCRA had closed floodgates at the Wirtz and Starcke dams on Saturday evening and that no floodgate operations were underway or planned at that time, but that could change with significant additional rainfall or runoff. Posts on its lake-level page record that the gates were closed, reopened and closed again over that weekend, that many Hill Country areas had received 3 to 5 inches of rain over the week, with some areas receiving more than 8 inches, and that on October 5 Lake Travis was 95 percent full after rain and floodwater passed through lakes LBJ and Marble Falls. For a buyer, the week is a reminder that lake levels in the same month can show both a flood operation and a statewide drought.

Statewide, the TWDB drought dashboard for a map dated October 6, 2026 shows 82.00 percent of Texas in moderate drought or worse, 52.44 percent in severe drought or worse, 13.49 percent in extreme drought or worse and 1.06 percent in exceptional drought. City rules follow the city's own water system, not only the lake. The City of Horseshoe Bay says it implemented the LCRA Stage 1 watering schedule effective July 16, 2025, limiting automated irrigation to two days a week, and the City of Marble Falls states that it is under Stage 2 mandatory water use restrictions, with watering once a week according to the last digit of the street address. Ask the city for its drought contingency plan and what each stage means for a lawn, a pool or a new landscape.

Flood coverage is a separate matter. FEMA states that most homeowners insurance does not cover flood damage, that flood insurance is a separate policy, and that homes in high-risk flood areas with mortgages from government-backed lenders must carry it. LCRA says FEMA and local officials, not LCRA, designate floodplains and control development in them, and that Lake Travis cannot prevent flooding on creeks and streams that feed the Colorado River. A lake lot should be checked against FEMA's Flood Map Service Center and the lot's elevation relative to the lake's flood pool or operating range, not only the day's lake level.

Lake Granbury and the Brazos River Authority

Lake Granbury is a Brazos River reservoir that the Brazos River Authority (BRA) describes as supplying water for much of Hood and Johnson Counties and the Comanche Peak Nuclear Power Plant, with six lakeside parks, six boat ramps and 121 miles of shoreline. The BRA's FAQ gives the elevation at capacity as 693 feet above mean sea level and says the authority considers the reservoir full at 692.7 feet. Its Drought Contingency Plan, dated May 20, 2024, manages Possum Kingdom, Granbury and Whitney as one subsystem and sets drought stages by combined conservation storage: a top of conservation of 729,287 acre-feet and a Stage 1 Drought Watch trigger at 570,002 acre-feet, Stage 2 at 432,438, Stage 3 at 294,874 and Stage 4 at 150,069. Because the stages follow combined storage, the level of Lake Granbury alone is a poor guide to drought status.

The BRA's resident FAQ sets the rules a waterfront buyer meets. It requires no annual fee for docks, but charges a one-time permit and inspection fee of $75 for a new dock, an addition or a title transfer when a home with a dock is bought, and it limits residential docks to 2,000 square feet. A retaining wall may be built at the 693-foot line, and a property with no dock must be checked with a BRA inspector to learn whether it qualifies for one. In subdivisions with canals, the land beneath the canals is privately owned, and the homeowners association, not the authority, maintains the canals and their retaining walls. The FAQ also says golden algae is present at Lake Granbury and most other northwest Texas rivers and reservoirs year-round and that fish kills occur only when the algae bloom and become toxic. As of October 8, 2026, the City of Granbury's home page carried a Stage 1 voluntary water conservation alert and Acton Municipal Utility District's page reminded customers that Stage 1 of its Drought Contingency Plan was in effect.

For health care, Lake Granbury Medical Center describes itself as a 73-bed facility at 1310 Paluxy Road serving Hood, Somervell and Erath Counties, and the system operates a freestanding emergency room on East Highway 377. Pecan Plantation and DeCordova Bend Estates, the lake and golf communities near Granbury, are described on their own pages. The Census Bureau's 2019-2023 survey estimates that 14.7 percent of Granbury's housing units are vacant, a lower figure than the resort lake markets discussed below.

Cedar Creek Lake and Gun Barrel City

Cedar Creek Lake is operated by TRWD, which places the 32,873-acre lake in Henderson and Kaufman Counties, about 80 miles southeast of Fort Worth. TRWD says a majority of the shoreline is privately owned, that it established Tom Finley Park as a public day-use waterfront park with a small admission charge, and that it publishes the lake's level above or below conservation level. The privately owned shoreline matters because the lake is public water managed by a district, while the lots around it are individual properties whose dock and shoreline use is subject to the district's rules. Buyers should read those rules and the district's level reports for any specific lot.

TRWD's July 2026 lake-level projections report is a regional example of timing. It says system storage rose from 89 percent at the end of May to approximately 91 percent by the end of June after heavy rains over the Richland-Chambers watershed, that July is historically one of the driest months in North Texas and one of the highest in water demand, and that El Niño conditions were present. That report covers the TRWD system and is not a Cedar Creek forecast.

Gun Barrel City is the commercial hub of the Cedar Creek Lake area, and its economic development corporation describes full-time residents, retirees and telecommuters as a growing part of the population. The Census Bureau's survey estimates that 11.8 percent of its housing units are vacant. For health care, the corporation lists a 24-hour emergency clinic with a helipad in the city, and places UT Health Athens, a hospital and intensive care facility, 24 miles away and Texas Health Presbyterian Hospital Kaufman 25 miles away. Those are the corporation's figures. A retiree with heart, stroke or cancer concerns should check where specialists practice and how long the trip actually takes.

Lake Conroe, Lake Ray Hubbard and Lake Lewisville

The San Jacinto River Authority publishes the most detailed numbers of any lake operator reviewed for this guide. Lake Conroe has 19,640 surface acres, about 150 miles of shoreline, a capacity of 412,200 acre-feet and an average depth of 20 feet. Its normal conservation level is 201 feet, the flowage easement is 207 feet and the average bulkhead height is 203 feet. The highest level on file was 206.24 feet on August 28, 2017, when the lake's maximum outflow of 79,141 cubic feet per second was also recorded, and the lowest was 192.68 feet, 8.32 feet below normal, on December 2, 2011. Our arithmetic puts the spread between the lowest and highest levels on file at about 13.6 feet, and that spread is the practical lesson: a lakefront lot can be flooded in one decade and far from the water in another.

The authority also says Lake Conroe began in September 2015 to supplement groundwater as a source of drinking water for Montgomery County, so the lake is a municipal supply as well as a recreation lake. Del Webb in Chambers Creek in Willis, an active adult community, advertises a private marina and access to Lake Conroe and a 9-hole golf course; see Del Webb in Chambers Creek. The community's own pages describe it as having direct access to the lake, while the developer's Willis page calls the setting a few miles from Lake Conroe, so a buyer should confirm exactly how a lot connects to the water. Conroe has HCA Houston Healthcare Conroe, which describes itself as a 332-bed acute-care hospital and tertiary referral center.

Lake Ray Hubbard is a Dallas water-supply lake. TWDB's survey data give it 20,947 acres of water surface and a storage capacity of 439,559 acre-feet at the conservation pool elevation of 435.5 feet, with a maximum depth of about 40 feet. TWDB's reservoir page showed the lake 85.9 percent full on October 8, 2026, at a mean level of 432.42 feet, compared with 100.0 percent on April 8, 2026 and 93.1 percent a year earlier. Our arithmetic puts the drop in fullness between April and October at about 14 percentage points. Rockwall has a hospital in the city, Texas Health Rockwall, on Horizon Road.

Frisco Lakes is a 55+ community on the east shore of Lake Lewisville in Frisco. The association describes amenity centers with pools, fitness centers and courts and does not market the lake itself as an amenity. This guide cites no operating page for Lake Lewisville, so the water level, the flood pool and any shoreline rules should be obtained from the agency that manages the lake. FEMA says its Flood Map Service Center is the official source for a community's flood map, and floods do not follow city limits or property lines. Frisco has three hospital campuses, which sets it apart from smaller lake towns.

Private lakes: Hide-A-Way Lake

Not every Texas lake is a public reservoir. Hide-A-Way Lake, the community that became the City of Hideaway in Smith County, has three lakes that sit inside a gated, member-governed community. The club describes over 1,600 homes arranged around 235 acres of lakes, and its amenities page lists three stocked lakes of 233 acres in total, so the two club pages give slightly different totals. Boat ramps, docks, fishing piers, a beach and an active lake and fisheries management program are among the listed features.

The club's rules, revised in February 2026, show what private ownership means in practice. Boats of any type used on the club's lakes must be registered with the club's security department and display a club decal, and motor-powered boats do not need the state licenses or certificates required for public waters. Personal watercraft are not allowed, boats of 22 feet and larger with certain hull types or wake-enhancing equipment are prohibited, wake surfing is prohibited by a 2024 referendum, and the direction of travel on the club's lakes is counterclockwise. The club rents slips it owns through its security office. A public reservoir imposes the state's boating rules and an authority's dock permits, and a private lake imposes the club's.

The tradeoff for a retiree is control against dependence. A member-governed club can set boat and wake rules that suit the people who live there, but lake management that an authority handles on a public lake becomes a club matter, so a buyer should ask the club what its budget and reserves provide for the lakes. Hide-A-Way's 2026 schedule lists a registration fee for boats and use of club-owned boat slips among the features of membership, and the City of Hideaway's own site describes the community as a gated residential community about thirteen miles northwest of Tyler. UT Health Tyler describes 424 licensed beds and a Level I trauma center that it calls the region's only one. The Census Bureau's survey estimates that 17.7 percent of housing units in the City of Hideaway are vacant.

Second homes, vacancy and who is there year-round

Lake markets differ in how many homes are occupied year-round. The Census Bureau's 2019-2023 survey estimates that 39.5 percent of the 3,801 housing units in Horseshoe Bay are vacant, and 17.7 percent in Hideaway, 14.7 percent in Granbury, 11.8 percent in Gun Barrel City and 10.3 percent in Lakeway. The survey does not say why a unit is vacant, so the percentages are signals rather than counts of second homes. They still bear on a retirement decision. A neighborhood with many part-time owners can be quiet in winter, may have fewer neighbors available to check on a house, and may be the place where a service provider cuts hours.

Horseshoe Bay's profile is the starkest. The same survey estimates that 47.9 percent of residents are 65 or older, and its hospital care is in neighboring towns. Baylor Scott & White Medical Center - Marble Falls, at 810 W. Highway 71 in Marble Falls, says it is open 24 hours, and the federal hospital file for Burnet County also lists Ascension Seton Highland Lakes, a critical access hospital in Burnet. Marble Falls has the Baylor Scott & White hospital inside the city, and Lakeway has Baylor Scott & White Medical Center - Lakeway, which describes itself as a 106-bed full-service hospital. Llano has a locally operated critical access hospital at 200 W. Ollie Street; the federal file lists it under its earlier name, Mid Coast Medical Center - Central. The guide to healthcare geography and Medicare explains critical access hospitals and why a plan network matters more than a map distance.

Questions to ask before buying on a Texas lake

Ask who operates the lake and what its purpose is: water supply, flood storage or both. Ask for the operator's published level history, including the lowest and highest levels on file, as the San Jacinto River Authority posts for Lake Conroe. Ask whether the lot sits above the operator's flood pool or flowage easement, using the FEMA flood map and an elevation certificate, and whether the lender will require flood insurance. Ask for the operator's dock rules and fees before assuming a dock is allowed, noting that the BRA tells owners of properties without docks to check eligibility with an inspector.

Ask the city or water provider for the drought contingency plan and the stage currently in effect. Ask the title company whether any district or association charge appears on the title commitment, a question the guide to HOA, condo, club fees and special assessments covers. Ask the HOA who maintains canals, seawalls and shoreline structures. For lake communities built around golf, see the companion guide to golf in Texas retirement markets. Finally, ask the plan and the physicians you use which hospital is in network, because a lake town with a hospital in town and a lake town with a hospital 24 miles away differ most on the day of an emergency.
