Aquilla Reservoir Raw Water Intake Water LevelNRNot rated for water quality
The USGS gauge at Aquilla Lake above Aquilla, TX last recorded a water elevation of 536.06 ft at Aquilla Reservoir Raw Water Intake on August 29, 2026. In Hill County, Texas, Aquilla Reservoir Raw Water Intake has no letter grade — the only measurement available is water clarity, which is not a water-quality indicator on its own — EPA's National Lakes Assessment does not grade clarity. Water clarity averages 2.0 feet of visibility. The water-quality samples behind that grade were submitted to the EPA Water Quality Portal by Texas Commission on Environmental Quality; the level above comes from the USGS, which runs the gauge.

Gauge 08093350, Aquilla Lake above Aquilla, TX, operated by the U.S. Geological Survey. The value above is the most recent reading on file with its own timestamp. When the gauge answers, it is replaced by the current one — no estimate is ever shown in place of a missing reading.
What this number is
Water elevation is the height of the lake surface above sea level, as surveyed at Aquilla Lake above Aquilla, TX. It is the number reservoir operators publish, and it is comparable from one reading to the next at this lake. It is not the depth of the water.

No target level is shown here. Saying a lake is high or low needs a conservation pool or a seasonal rule curve to measure against, and the gauge reading alone does not carry one. The station page above holds the full record, including the last several days, which is what a single reading has to be read against.
Water quality at Aquilla Reservoir Raw Water Intake
Aquilla Reservoir Raw Water Intake has no letter grade. The only measurement available is water clarity, which is not a water-quality indicator on its own — EPA's National Lakes Assessment does not grade clarity. A lake without enough recent summer sampling is published as Not Rated rather than given a letter the data cannot support. Not Rated is never an F.
The gauge measures how much water is in the lake. The grade measures what is in the water. A rise or a drawdown does not change the letter until the lake is sampled again.

Common questions
What is the water level at Aquilla Reservoir Raw Water Intake right now?
The most recent reading from the USGS gauge at Aquilla Lake above Aquilla, TX is a water elevation of 536.06 ft, taken on August 29, 2026. This page reloads that gauge every time it is opened, so the number above is the current one whenever the station is reporting. USGS lake gauges typically post a new value every 15 to 60 minutes.
What does water elevation mean?
Water elevation is the height of the lake surface above sea level, as surveyed at Aquilla Lake above Aquilla, TX. It is the number reservoir operators publish, and it is comparable from one reading to the next at this lake. It is not the depth of the water.
Is Aquilla Reservoir Raw Water Intake low?
That question needs a target pool level to answer, and the gauge reading alone does not supply one. Reservoir operators publish a conservation pool or a seasonal rule curve for the lakes they manage, and the USGS station page for gauge 08093350 carries the full record this reading came from, including the past several days. Comparing today against that record is the honest version of "low" — a single number is not.
Does the water level affect water quality at Aquilla Reservoir Raw Water Intake?
Aquilla Reservoir Raw Water Intake has no letter grade — the only measurement available is water clarity, which is not a water-quality indicator on its own — EPA's National Lakes Assessment does not grade clarity. Lakes are graded A to F on nutrients and algae — total phosphorus, total nitrogen, chlorophyll-a, and turbidity — measured against the EPA National Lakes Assessment 2022 condition classes for that lake's own ecoregion, so a lake is judged against the lakes it would naturally resemble. None of that comes from the gauge. A drawdown can concentrate nutrients and a heavy inflow can dilute them, but neither shows up in the grade until the water is sampled again. Treat the two numbers as separate measurements of the same lake.
Where these numbers come from
The level and temperature are U.S. Geological Survey instantaneous values from gauge 08093350, a public feed with no licence restriction. The water-quality grade is built from EPA Water Quality Portal samples submitted by Texas Commission on Environmental Quality. For advisories and standards in Texas, TCEQ is the authority — a gauge reading is neither.
