the time wo aid be shortened down to a few months. In the past we have 

 heard that the publication of chart information has been as much as 

 6 years after collection of the data. 



Dr. White. An average time of 1 to 2 years is still required from 

 completion of a hydrographic survey to publication of a chart based 

 on that survey, because ESSA has not had the necessary resources to 

 implement the automated data processing system. The most critical 

 data, about 40 percent of the complete survey, is applied to the chart 

 during this 1- to 2-year period. The remainder is applied over the next 

 3% years or so. As a result only about 40 percent of the available hydro- 

 graphic survey data is presently being applied to the charts. 



Mr. Drewry. What progi^ess has been made in the past several years 

 in the small boat chart program? Wliat areas are now covered? How 

 are they being received by the public ? 



Dr. White. The first Coast and Geodetic Survey small-craft chart 

 was published in 1959. Today 59 are on public issue. However, 20 of 

 these are of the area type; that is. conventional nautical charts folded, 

 overprinted Avith additional information for small-craft and issued in 

 a suitable jacket. One hundred and forty additional new small-craft 

 charts are needed to cover navigable waters frequented by small-craft. 

 Small-craft new chart production was limited to five charts in fiscal 

 year 1967. 



The coverage of present small-craft chart areas along the east coast 

 includes : 



Beginning in Maine, Penobscot Bay and River, Damariscotta, 

 Sheepscot and Kennebec Rivers. 



In Massachusetts, Boston Harbor; Cape Cod Canal, Buzzard's Bay 

 and the southside of Cape Cod. 



In Rhode Island, Narragansett Bay. 



In Connecticut, New York, and New Jersey.

 Florida the coverage includes the St. Lucie Canal, Lake Okeechobee, 

 the Caloosahatchee River, and the west coast of Florida from Fort 

 Myers to Tampa Bay. 



In Florida, Alabama, Mississippi, and Louisiana, the small-craft 

 charts cover the inland waterwav from Nensacola Bay, Fla., to Bayou 

 Lafourche, La. Also covered in Louisiana is Calcasieu Lake. 



In Texas, Galveston Bay and the inland waterway from tliere to 

 Matagorda Bay are covered.
