Cross Check Survey

Questionnaire Supplement

Dear Contributor

Some of our commissioners and crosscheck contributors have recommended a few additional questions relating to dam projects that would add value to the findings of this survey. the wcd has endorsed their requests by adding these additional questions.

These questions will supplement the main questionnaire which you have or are currently completing.

The questions are fairly general in nature to minimise revisits to project archives or additional time and resource demands.

Please fill in and return this supplementary questionnaire to the wcd by not later than 29 february 2000.
Our fax no is: +27 21 426 0036

Your co-operation in this regard is be sincerely appreciated.
