         American River Bankshares Announces First Quarter 2007 Earnings

Sacramento, CA, April 19, 2007 - American River Bankshares (NASDAQ - GS: AMRB)
today reported net income for the first quarter of 2007 of $2,086,000, a 7.0%
decrease from $2,243,000 for the quarter ended March 31, 2006. Diluted earnings
per share for the first quarter of 2007 were unchanged at $0.37 per share from
the first quarter of 2006.

"The primary focus of our strategic plan remains to grow American River
Bankshares' profitability, which means making prudent decisions for long-term
success," said David Taber, President and CEO of American River Bankshares. "Our
financial metrics continue to differentiate our Company as a solid performer."

Net interest income for the first quarter of 2007 decreased 3.6% to $6,547,000
from $6,792,000 for the first quarter of 2006. Interest income for the first
quarter of 2007 increased 3.8% to $9,464,000 from $9,117,000 for the first
quarter of 2006. Average earning assets decreased $11,365,000 (2.1%) from the
first quarter of 2006 to the first quarter of 2007; the decrease is mainly the
result of a planned reduction in the investment portfolio. The proceeds were
primarily used to pay down short-term borrowings. The average level of loans
increased quarter over quarter by $16,841,000 (4.5%), which helped to increase
the interest income for the quarter. Although borrowings were down, interest
expense for the first quarter of 2007 increased 25.5% to $2,917,000 from
$2,325,000 for the first quarter of 2006. This increase is primarily related to
increased interest rates as a direct result of the higher overall rate
environment. The average yield on interest bearing liabilities increased 72
basis points from 2.46% during the first quarter of 2006 to 3.18% during the
first quarter of 2007.

Noninterest income for the first quarter of 2007 increased 1.1% to $641,000 from
$634,000 for the first quarter of 2006. Noninterest expense for the first
quarter of 2007 increased 1.5% to $3,692,000 from $3,638,000 for the first
quarter of 2006.

Net loans as of March 31, 2007 decreased $3,347,000 (0.9%) to $379,646,000 from
$382,993,000 as of December 31, 2006 but increased by $6,892,000 (1.8%) from
$372,754,000 as of March 31, 2006. Total deposits as of March 31, 2007 decreased
$8,131,000 (1.6%) to $485,744,000 from $493,875,000 as of December 31, 2006 and
decreased $10,212,000 (2.1%) from $495,956,000 as of March 31, 2006. Short-term
borrowings decreased 46.1% to $20,083,000 at March 31, 2007 from $37,270,000 at
December 31, 2006 and are down 49.8% from $40,029,000 at March 31, 2006.

Credit quality remains sound, with nonperforming loans and leases at 0.20% of
total loans and leases compared to 0.02% last quarter and 0.04% one year ago.
The allowance for loan and lease losses increased slightly to $5,935,000 as of
March 31, 2007 from $5,874,000 as of December 31, 2006 and increased from
$5,767,000 as of March 31, 2006. The provision for loan and lease losses was
$121,000 for the first quarter of 2007, an increase from $84,000 for the first
quarter of 2006. The reserve as a percentage of loans and leases was 1.54% at
March 31, 2007, compared to 1.51% at December 31, 2006 and 1.52% at March 31,
2006. Non performing assets were $766,000 and net chargeoffs were $60,000 for
the quarter ended March 31, 2007 compared to non performing assets of $78,000
and net chargeoffs of $47,000 for the quarter ended December 31, 2006.

Tangible Equity (ROATE) was 19.89% and the efficiency ratio was 49.68%. For the
