The crisis involving Maryland's state-chartered thrift institutions has tied up the funds of thousands of local investors, including Dorothy Blackmun, wife of Supreme Court Justice Harry A. Blackmun. She had $5,000 to $15,000 deposited in Chevy Chase Savings and Loan, according to the annual financial-disclosure statements released last week by the Supreme Court.

The Maryland situation should not have put much of a crimp in the family budget, however. Blackmun, according to his disclosure statement, is the court's fourth-wealthiest justice, with assets of $216,000 to $630,000.

That is peanuts, however, compared with the portfolio of Lewis F. Powell Jr., the court's wealthiest justice, whose 20-page disclosure form shows assets of $2.6 million to $5.6 million.

The disclosures, required by the Ethics in Government Act, reveal only broad ranges of assets and do not include the justices' salaries. Nor do they require disclosure of the value of the justices' homes.

At the bottom end of the court scale was Justice Thurgood Marshall, whose essentially blank, four-page form listed only an account in the First Federal Savings and Loan of Northern Virginia worth $5,000 to $15,000.

The court has two other likely millionaires -- Chief Justice Warren E. Burger, who reported $665,000 to $1.02 million in assets and Justice Sandra Day O'Connor, whose ledger sheet showed assets of $996,000 to $2.2 million.

The other justices' holdings showed William H. Rehnquist with between $169,000 and $470,000 in assets, Byron R. White at $60,000 to $200,000, William J. Brennan Jr. at $56,000 to $190,000 and John Paul Stevens at $35,000 to $115,000.

Anyone considering charitable contributions to the poorer justices should note that they receive a salary of $100,600, while the chief gets $104,700.
