Generalized surficial geologic mapping at 1:62500 scale shows 

 only undifferentiated glacial deposits in the Nine Pipe area. 

 Generalized potentiometric mapping shows a northward trough in 

 regional surface beneath the reservoir. [This looks kind of strange 

 and improbable, really.] Very generalized text, with no discussion 

 of shallow flow systems in Nine Pipe area. Includes tabulated 

 water chemistry from a number of wells in regional aquifer.

Title: Irrigation-canal leakage in the Flathead Indian 

 Reservation, Northwestern Montana 



Series: U.S. Geological Survey Water-Resources Investigations 

 Report 92-4066 



Date: 1992 



This study used seepage-meter estimates of canal seepage at 5 sites 

 on hydrogeologically distinct materials and a GIS of the canal 

 system to generate canal seepage estimates for the entire Flathead 

 Irrigation Projects system. One of these sites (the Charlo site) 

 was on the Mission moraine, underlain by till of the same map unit 

 as that underlying the Ninepipe sites several miles distant. 



Observed differences in hydraulic conductivity correlated with 

 differences in monitoring well response to canal head. In till 

 facies of lower hydraulic conductivity, monitoring well response 

 was subdued and only generally correlated with canal flows, while 

 wells in more permeable till facies showed direct responses.
