Exhibit 99.1

                   Eagle Rock Energy Partners, L.P.
        Reports Results for Fourth Quarter and Full Year 2006


    HOUSTON--(BUSINESS WIRE)--April 2, 2007--Eagle Rock Energy
Partners, L.P. (Nasdaq:EROC) today reported its financial results for
the fourth quarter and full year ended December 31, 2006.

    For the fourth quarter of 2006, the Partnership reported $115.7
million of revenues as compared to $57.4 million for the fourth
quarter of 2005. Total revenues for the year ended December 31, 2006
were $478.4 million as compared to total revenues of $73.7 million for
the year ended December 31, 2005.

    The Partnership reported a net loss of $11.7 million for the
fourth quarter of 2006, compared to net income of $3.2 million for the
same period in 2005. Net loss for the fourth quarter of 2006 included
a $4.8 million net loss for unrealized risk management activities as
compared to an $8.9 million net gain for the fourth quarter of 2005.
Additionally, during the fourth quarter of 2006, the Partnership
recorded a pre-tax $6.0 million expense related to the termination of
an advisory services agreement, which contributed to the net loss
reported. Net loss for the year ended December 31, 2006 was $23.3
million as compared to net income of $2.7 million for the year ended
December 31, 2005. Included in net loss for 2006 was $23.5 million net
loss of unrealized risk management activities as compared to $8.9
million of net gains for unrealized risk management activities in
2005, in addition to the pre-tax expense attributable to the $6.0
million expense related to the termination of an advisory services
agreement.

    Adjusted EBITDA for the fourth quarter of 2006 was $19.0 million,
which was in the guidance range the Partnership reported earlier. For
the fourth quarter of 2005, adjusted EBITDA was $3.1 million. Adjusted
EBITDA for the year ended December 31, 2006 was $81.2 million as
compared to $3.4 million for the year ended December 31, 2005.

    The increase in revenues and adjusted EBITDA for the fourth
quarter of 2006 as compared to the previous year's fourth quarter
reflects the impact from a full quarter inclusion of the Panhandle
Texas acquisition (assets acquired December 1, 2005) and the
Brookeland and MGS acquisitions during 2006. The improvement in
results also reflects the impact of the organic growth projects during
the year including the first phase of the Tyler County Pipeline
project, as well as the growth from the well attachment programs
during the year.

    The Partnership also announced the filing of its Annual Statement
on Form 10-K for the year ended December 31, 2006 with the Securities
and Exchange Commission.

    Eagle Rock will host a conference call to discuss financial
results and the previously announced potential acquisitions, financing
and organizational changes on Wednesday, April 4, 2007, at 9 a.m. CT
(10 a.m. ET). Interested parties may listen live over the Internet or
