The Environmental Protection Agency has released 111 official photos from the site of Exxon Mobil's Pegasus Pipeline spill in Mayflower, Ark. Part of the underground pipeline ruptured March 29, prompting emergency responders to evacuate 21 nearby homes.

The EPA now estimates that between 4,000 and 7,000 barrels of oil was released. Images show that oil reached into a creek and partially into Lake Conway.

"The damaged pipeline released Wabassa Heavy crude oil into the North Woods Subdivision," according to the EPA. "Crude oil then flowed west along N. Starlite Road, into a bar ditch adjacent to a Union Pacific Railroad line, into an unnamed creek."

The EPA reported that it found 14 oiled ducks, five turtles, six snakes and one muskrat alive and recovered for treatment. It also found five dead ducks."
