Ground surveys, using total-station equipment with datalogger, will be based on recoverable range points established for the 1982 survey. X and Y coordinates are in latitude-longitude or distances and angles from transit points. Elevations are based on mean sea-level datum. Survey data will be used to produce a topographic map showing contour intervals of 10 feet. The stage- capacity curve will provide city managers with the amount of water in the reservoir on a daily basis.
Capacity is related to stage which can be obtained by staff readings at any time.
The size of deposited sediments will be measured by sieve analysis of bottom samples at the California District sediment laboratory in Salinas.
