- When purchased, the property had 4 wells (3 for irrigation and 1 domestic use). No documentation on new wells can be found, and one well was abandoned after purchase.

- State Well No. 12/4E-6E(1), Appl. No. GR-854: SEC 6, TWN 12S W4 . Loc from SEC corner:

S. 21.5 30’E. 1600 ft. from NW cor. SEC 6. Constructed June 1954. Drill depth 34 ft. 6 in steel casing to 34 ft.

- State Well No. 12S/4W-6, No permit number. No location info. Constructed August 1983. Drill depth 90 ft. 10 in steel casing to 36 ft.

- State Well No 12S/4W-6. No permit number. No location info. Constructed August 1983. Drill depth 51 ft. 10 in steel casing to 36 ft.

- Well Locations: See map. It is unknown which well corresponds to the well information above.

- Current Flow Rates: unknown.

Current irrigation system status. See system maps attached. These maps are not up to date with all piping modifications.

Well #1.

- Pump system suboptimal operation

- Marked #1 on colored plot map. Marked #2 on 1991 map.

Well #2.

- Pump system is operational and has the highest horsepower pump.

- Considered the most reliable water supply and has the widest diameter discharge.

- Marked #2 on colored plot map. Marked #1 on 1991 map.

Well #3.

- Pump system operational and has the newest and most modern pump. Has Variable

Frequency Drive, VFD.

- Best quality water (least amount of iron bacteria), but the least reliable (the lowest volume).

- Marked #3 on colored plot map. Marked #3 on 1991 map.

Problems:

- Current configuration is incapable of meeting demand.

- Automation between wells needs repair/replacement for flow/pressure regulation.

- Automation of system valves for zones needs repair/replacement.

- Stationed filtration systems need repair/replacement for iron bacteria.
