2009 Gila Science Forum (12/2009)

The general purposes of the 2009 Gila Science Forum were to identify, discuss, and recommend: (1) ways of determining the potential effects of flow modification on aquatic and riparian resources of the Gila River (including risks and uncertainty), and (2) how information gleaned from such efforts might be integrated to provide an ecosystem-based assessment of the effects.

Draft Technical Memorandum re: Gila River - April and May 2010 fieldwork (6/15/2010)

Tetra Tech staff conducted field investigations along the Gila River, New Mexico from April 12th through May 5, 2010. The work was implemented in a manner consistent with the Gila River Study Plan (March 4, 2010) which describes the study being undertaken by the New Mexico Interstate Stream Commission (NMISC) and its consultants and collaborators. The field investigation included: (a) coordinating with the NMISC, collaborators and land owners to arrange access to monitoring locations along the Gila River; (b) drilling and constructing of monitoring piezometers near the river; (c) equipping the monitoring piezometers with pressure transducer / dataloggers in order to establish a long-term groundwater elevation monitoring network; (d) installing and equipping river stage gages at two monitoring locations; (e) completing a detailed site survey, including river cross-sections and piezometer and stage gage locations and elevations; and (f) associated field activities such as logging of subsurface geology, and piezometer development.
