D.C. Mayor Marion Barry has raised a record $905,061 in campaign contributions, far outdistancing his competitors in total fund raising for the Sept. 14 Democratic primary, according to campaign financial disclosure reports filed yesterday.

Barry's closest rival in the polls, Patricia Roberts Harris, reported that she has raised a total of $506,750. Council member John Ray (D-at-Large) reported a total of $316,350 for the year, and council member Charlene Drew Jarvis (D-Ward 4) reported $65,647.

Ray has $7,115 on hand. He has spent $39,691 in the last two months while raising only $26,843, according to his report. Jarvis' report indicated she raised $36,722, more than half her money, in the last two months. She has spent $41,087, leaving her with $24,560 on hand for the rest of the race.

Barry's report to the Office of Campaign Finance yesterday showed him only about $100,000 ahead of Harris in cash available just five weeks before the election. Barry reported $211,480 cash on hand while Harris reported $118,763.

In the contest for City Council chairman, incumbent Chairman Arrington Dixon reported raising a total of $153,617 and council member David A. Clarke (D-Ward 1) reported raising $66,270.

Former chairman Sterling Tucker, who entered the race in early June, reported raising $52,444, about 72 percent of which was contributed by lawyers or their families.

Dixon reported about $43,000 cash on hand, while Clarke reported about $41,000 and Tucker listed about $18,000 cash on hand.

On the Republican side, mayoral candidate E. Brooke Lee Jr. reported raising a total of $28,018 in his race with James Edward Champagne. Champagne's financial disclosure statement was not available late yesterday. Lee, who has $392.74 on hand, also had outstanding loans of $10,333. He made most of the loans to himself.

Barry's fund-raising total of nearly $1 million is unprecedented in District politics. When he won the 1978 primary he raised under $300,000. His two challengers, incumbent Walter Washington and former City Council chairman Sterling Tucker raised more than $300,000 each as the front-runners in that race.

Even though total fund raising continues at a record clip, contributions to Barry's campaign have slowed from the last two months' fund-raising period, April to June, when Barry reported raising $313,643. He has raised $213,142 since June.

Barry reported spending $358,005 in the last two months. For the entire campaign he has spent more than two-thirds of his contributions -- $693,581.

Barry has paid his campaign staff $208,977 in salaries. He has spent $482,214 on advertising. Barry's radio advertisements start this week and he has plans to begin television advertising next week.

Meanwhile Harris, who started her television advertising last Friday, has spent $289,387 on producing advertisements.

Ray said recently he may have to forego television advertising because of his cash shortage and that his radio advertising may be limited. Jarvis said yesterday she plans no television advertising and instead has purchased four vans in which she will ride around the city and campaign.

Harris raised $190,598 in the last two months, much of it from local unions including the Hotel and Restaurant Workers Local 25 AFL-CIO; the United Food and Commercial Workers Union; the Sheet Metal Workers; the Engineers Political Education Committee; the International Brotherhood of Electrical Workers and the International Bridge Structure and Ornamental Ironworkers Union. They all contributed $2,000 apiece to her campaign.

In one fund-raising effort, a breakfast with singer Lena Horne, Harris raised over $13,000.

In his first report since entering the chairman's race, Tucker showed a total of 100 contributions, 60 of which were from attorneys or their families. The report showed 16 contributions of $1,000 and four contributions of $1,500 from the attorneys. The individual legal limit in the chairman's race is $1,500.

Many of the lawyers who contributed to Tucker are members of the Association of Plaintiff Trial Lawyers, which strongly opposed recently passed no-fault auto insurance legislation here. Tucker has vowed to amend the law if elected chairman.

Donald Chaiken, president of the trial attorneys association, said yesterday that his group was not engaged in an organized effort to raise money for Tucker but said he felt many trial attorneys "wanted to show their protest to Dixon," a principal backer of the no-fault bill.

Dixon, who raised about $76,000 in the past two months, showed a continuing trend of support from business and professional groups, but his advisers said he probably will not meet his target goal of $350,000. They said the mayor's race and the poor economy has drained money from all lesser races.

Dixon's contributions included $600 from the Pepco Political Action Committee and $1,500 from the Government Employes Insurance Company (Geico), the firm that helped lead lobbying for the no-fault bill.

Dixon also reported collecting $35,642 from a July 1 "Businessmen's Salute to Arrington Dixon." Republican at-large council member Jerry A. Moore Jr. gave Dixon $50.

Clark reported a total of 437 contributions in the current period, most under $150 and scattered about the city. In his June report, Clark's contributions generally had come from Ward 1, the in-town area he has represented for the past eight years.

Clark's report included contributions from tenant activists, retail liquor dealers and several persons who simply listed themselves as "retired." He also received about $3,000 from union groups that have endorsed him.
