A study containing of a detailed topographic survey of main ditch reaches and concurrent hydrologic monitoring in order to assess non-winter drainage conditions in the ditch network at Carr Lake.
Landowners at Carr Lake reported increasing issues with proper drainage of the agricultural fields that made up the vast majority of the former lake bed. The primary driver of the study was the recognition that a more complete understanding of the site topography and hydrology is necessary, both to frame the pertinent issues and to identify any measures that may be appropriate to enhance drainage in the ditch system. Therefore the project work plan included two main fieldwork components, topographic survey and hydrologic monitoring. The fieldwork was followed up by data post processing, mapping, and associated supporting analyses.
Work was completed under authorization of the Monterey County Water Resources Agency to assess non-winter drainage conditions in the ditch network at Carr Lake, part of the much larger Zone 9 Reclamation Ditch system. The work plan consisted of two principal components: a detailed topographic survey of the main ditch reaches and concurrent hydrologic monitoring in order to better understand the opportunities and constraints that exist with respect to providing efficient dry-season drainage within the on-site ditch network. Field work extended from late April through October of 2014, with subsequent post-processing of data, associated analyses to put the data in a regional and historical context, and preparation of project mapping.
