• Distribution of Streamflows for Control Points A10 and A40 for 1976

• The results are as expected. The flows at A10 are higher since the point is located further downstream in the system. Also, we can see that the flow is higher in the summer months when there is more rain falling on the basin.

• Use of NRCS Flow Redistribution Method to Calculated Flow at Unknown Point

• Solving by the quadratic equation gives P = 1.037 in.

• Therefore, Q₄₀ by NRCS method is approximately equal to the 138 acre-ft/mo calculated by WRAP.

where a = 

• Q₄₀ by the drainage area ratio method is approximately equal to 158.55 acre-ft/mo.

% diff = 13.2%

#2)

• The senior water right holder is the City of Wolfe City

• The seniority of this water right means that it is entitled to all of its water before anyone else gets theirs.

#3) Naturalized, Unappropriated and Diverted Flows

The average annual naturalized and unappropriated flows out of the basin can be found from the data in the file output1.

• NATURALIZED = 311,881 AC-FT/YR, UNAPPROPRIATED = 150,561 AC-FT/YR

• APPROPRIATED = 311,881 - 150,561 = 161,320 AC-FT/YR
• % DIVERTED = 161,320/311,881 = 51.7%

• As you can see by the scatter in the data, the appropriated water is not constant from year to year. If it was, you would be able to see some sort of correlation in the data points (i.e. it would plot as a straight line).

• After running the example2 file through TABLES, a plot was made of the End of Period Storage as a function of time (see below):

• From the plot and the data in the tables, we can see that the storage goes to zero between October of 1955 and January of 1957. It also breifly goes to zero again during the summer of 1964.

• The fact that the storage goes to zero implies that the supply of water to Irving was not very reliable. A drought during that time caused the depletion of the reservoir storage, and thus limited the supply of water to that area of Texas for a period of 16 months.

• Below is a table displaying the impacts of the new water right on the existing water right holders:

• The new water right does not affect the reliability of supply to the other water right holders in the basin apart from those drawing from Chapman Reservoir. Since this water right would be the most junior in the basin, the other water rights are entitled to their water before WR5000 gets its water. It affects the water rights drawing from Chapman Reservoir because they are all pulling water from the same source.
