Lake Granbury Homes: What a Lower Lake Level Means for Waterfront Buyers and Sellers

Late summer is when a lake tells you the truth. Lake Granbury has dropped through the summer, and if you're shopping for a waterfront or lake-access home, the water line is something worth understanding before you make an offer.

How low is Lake Granbury right now?

The Texas Water Development Board's Water Data for Texas tracks the reservoir. Its figures show Lake Granbury at 92.5 percent full on Aug. 2 and 87.6 percent full on Sept. 9, which was an elevation of about 690.59 feet. The conservation pool, which is the lake's normal full level, is 692.70 feet. That puts the lake a little over two feet below normal as of the Sept. 9 reading. The site notes that its data is provisional and subject to revision, so check the page for the current number.

Lake levels move for ordinary reasons. Summer heat, evaporation, upstream releases, and water use all play a part, and the Brazos River Authority manages the lake as part of a larger system. A lower lake isn't a problem by itself, but it changes how some properties look and work.

What does it mean for waterfront buyers and sellers?

If you're buying, visit more than once, and ask when the water was last at the level you're seeing:

• Dock and boat access. A dock that works at full pool may look very different two feet down. Ask how the dock and ramp perform at lower levels.
• Shoreline and permits. Ask what permits exist for the dock, any shoreline work, and whether they transfer to a new owner. The Brazos River Authority is the place to confirm what applies to a specific lot.
• Views. A cove can look different when the water pulls back. See the property in more than one season if you can.
• Insurance and flood risk. Ask for the flood zone, and get insurance quotes before you're under contract.

If you're selling, be upfront. Buyers will check the lake level, so have your dock and permit paperwork ready and be honest about how the property looks at different levels.

If you're not on the water but want lake-area living, remember that "Lake Granbury homes" covers a lot of ground. Some are on the shoreline and some are a short drive away. The tradeoffs in price, upkeep, and access are different.

My take: what I'd do right now

1. Pull the current lake level. Look at the Water Data for Texas page for Lake Granbury and note the date of the reading.
2. Ask about the dock in writing. What is it, what's its condition, and what permits does the seller hold?
3. See it twice. Once on a calm weekday and once on a weekend when the lake is busy.
4. Get the survey and flood information. Know exactly where your property line meets the shoreline and the flood zone.
5. Ask your lender and insurer early. Waterfront financing and insurance can have extra requirements.

Tax, insurance, and lending questions belong with your CPA, agent, and lender.
