| 12 Aug 2005 | Well inside large locked shed. Well not located or measured. Owner reticent about allowing access unless called a day ahead of time. Not considered for ongoing monitoring for this reason. |
| 20 Oct 2006 | On three occasions in summer 2005 this well failed. Winter 2006 quantities of sand and git material coming through pump. |
