EXHIBIT 99.1



                                             April 5, 2000






Dear Participant:

     As of March 29, 2000, the trust ("DRP Trust") established for
the Columbia Federal Savings Bank (now known as CFS Bank, the
"Bank") Recognition and Retention Plan for Outside Directors
("DRP") held 13,982 shares of common stock of Haven Bancorp, Inc.
(the "Company"), the parent holding company for the Bank.  As a
participant in the DRP, you may direct the voting of the shares of
the Company's common stock held by the DRP Trust that have been
granted to you under the DRP.

     Chase Manhattan Bank has been appointed as an unrelated
corporate trustee for the DRP Trust (the "DRP Trustee").  We, the
Board of Directors, are forwarding to you the attached Vote
Authorization Form, provided for the purpose of conveying your
voting instructions to the DRP Trustee.  The DRP Trustee will vote
those shares of the Company's common stock held in the DRP Trust
that have been granted to participants in accordance with
instructions received from the participants. If the DRP Trustee
does not receive voting instructions with respect to shares that
have been granted to participants, the DRP Trustee will vote such
shares in the same proportion as it votes the shares for which it
has received voting instructions.

     At this time to direct the voting of shares granted to you
under the DRP, you must complete and sign the enclosed Vote
Authorization Form and return it in the accompanying envelope to
ChaseMellon Shareholder Services L.L.C. ("ChaseMellon"). Your vote
will not be revealed, directly or indirectly, to any director,
officer or other employee of the Company or the Bank. Your shares
will be tallied by ChaseMellon on a confidential basis.
ChaseMellon will then provide the tabulated results to the DRP
Trustee. The DRP Trustee will then vote the shares in the DRP Trust
based on the voting instructions it has received from participants,
as described above.

                                        Sincerely,




                                        The Board of Directors


                    HAVEN BANCORP, INC.
