The phrase "average annual water" is correct and usable in written English.
It can be used when discussing the typical amount of water measured or used over the course of a year, often in contexts related to environmental studies, agriculture, or water resource management.
Example: "The average annual water consumption for a household in this region is approximately 50,000 gallons."
Alternatives: "yearly water average" or "annual water mean".
The average annual water bill is £330.
The average annual water temperature in the western part of the lake is 50° F (10° C); in the eastern part it is 48° F (9° C).
Cuadrilla has told regulators each of the 45 "stages" of the well it is fracking will use up to 765 cubic metres of water – the equivalent of five homes' average annual water use.
The proposed model, designed such as to effectively estimate the average annual water supply for the various mountainous watersheds, accepts as inputs a wide range of meta-data produced via an evolutionary genetic process.
Results show that significant improvements in both policy aims can be achieved through expanding existing storage capacity to capture up to 150percentt of long-term average annual water supplies when added capacity is combined with either a proportional sharing of water shortages or unrestricted water trading.

The rate of water consumption in most countries in the region already exceeds the harnessed renewable water supply: at the present population growth rate, the average annual available water per indigenous capita will drop further to ~100 m3 or less by the year 2020 (Håkan and Jägerskog 2006).
Examples of CWD under higher than average annual precipitation (water year 1998; Figure 10a) and lower than average annual precipitation (water year 1977; Figure 10b) indicate the influence of energy loading on slopes.
The difference between the simulated average annual ground water recharge in the two cases is 30.4 mm.
The average annual fresh water resources are estimated at 22 billion cubic metres, which is equivalent to 730 m3/capita/year.
The average annual ground water recharge given by the two models is between 13 and 15 mm.
