Item 8.01. Other Events.


On September 13, 2007, Eagle Rock Energy Partners, L.P. ("Eagle Rock" or the
"Partnership"), pursuant to its stated strategy of mitigating its commodity
price exposure and reducing the volatility in its cash flows, entered into a WTI
crude oil swap for 2008 on 80,000 barrels per month at a swap price of $73.90.
Eagle Rock also entered into WTI crude oil collars to reverse out-of-the-money
collars for 2008 production of the same 80,000 barrels per month, at a cost of
approximately $9.1 million. The combined impact of these two transactions was to
raise Eagle Rock's floor on those volumes by $23.90 per barrel while at the same
time raising its cap by $6.51 per barrel to its swap price of $73.90.
