There are several shallow subsurface diversions consisting of springs and infiltration galleries located adjacent to the G~rley Ditch near the surface diversion point. :Some of the subsurface diversions have been completely abandoned. The likely water source for t~ese subsurface diversions is natural ground water f~ow and recharge from flow in the Gurley Ditch, althqugh irrigation runoff probably contributes also. The waterflow of the various subsurface systems has not been well documented, since there are no individual measurement devices. Based on information provided by the Town of Norwood, it appears that qnly a portion of the subsurface diversions hav~ water rights filings. Also, since the descriptiqns are somewhat sketchy, (and inaccurate) it is di~ficult to correlate the water right filing with the actual diversion. Thus, the terminology used herein for the various subsurface diversions must be considered approximate and additional research m~y be needed. The subsurface diversion systems in use includes the following (Figure III-B):! Gardner Sprinas and pfpeline. This is a combination spring and infiltration gallery. (Priorities No. 478 and 511.) Norwood Infiltration Pipeline. This system consists of perforated pipe located below infiltration ponds (p~iority No. 513). , Abandoned subsurface wate~ systems include the following: Infiltration Pipe East of Town Reservoir. This is an abandoned infiltration gallery located north of Gardner Springs. No water right filing was found. It is shown on the 1977-78 plans; no other information is available. 'Water Plant' Infiltration Gallerv. There is also an old infiltrat~on gallery (also shown on the 1977-78 plans) loqated 500 feet south of the water treatment plant. No water rights filing was found; no other information is available.
