Lake Nasworthy is the 1,380-acre city lake on San Angelo's southwest side, impounded in 1930 and held at a nearly constant level by water released from Twin Buttes upstream. The homes around it split into two kinds: waterfront lots with private docks, and brick ranch homes in planned sections a few streets back. Downtown is about eight miles by road.

The housing
On the water, the product is the lot as much as the house: shoreline frontage, a private dock, and whatever was built on it since 1930. Back from the water, planned sections of brick ranch homes fill in the streets between the shore and Knickerbocker Road. The two trade very differently depending on whether the lot touches the lake.

Taxes
Which units tax a lake-area home depends on whether the parcel sits inside the city limits, and the line is not obvious from the street. Every parcel here pays San Angelo ISD and Tom Green County; parcels inside the city also pay the city. The 2025 adopted rates, per $100 of taxable value:
| Taxing unit | 2025 rate per $100 |
|---|---|
| San Angelo ISD | $1.0706 |
| Tom Green County | $0.4708 |
| City of San Angelo (inside city limits only) | $0.7947 |
| Combined, inside city | $2.3361 |
| Combined, outside city | $1.5414 |

Things to know before you buy
- The level is the point. Texas Parks and Wildlife describes Nasworthy as having a "nearly constant water level maintained by discharge from Twin Buttes Reservoir." Twin Buttes itself swings 6 to 8 feet a year. That is why a Nasworthy dock stays usable and a Twin Buttes shoreline moves.
- The city controls the lake. The San Angelo Parks and Recreation Department controls the reservoir, and Nasworthy, with Twin Buttes, feeds the South Concho system in the city's water supply. Lake rules and drought stages come from the city.
- Ask about the dock. If the home has one, find out what approvals it carries and whether they transfer with the sale.
- Twin Buttes needs a permit. A Limited Public Use permit ($12 a year, age 17 and up) is required to fish, hike, camp, or picnic there, sold through Texas Parks and Wildlife's public hunting program and expiring each August 31.
- File the homestead exemption if this will be your primary residence (Form 50-114, generally due before May 1); the school district exemption is $140,000, and your taxable value then cannot rise more than 10 percent a year.
