the Pakistani fly to control hydrilla in DeGray Lake. The "Pak" fly larvae were supposed to eat the tops off hydrilla plants down to a depth where it would decrease total plant coverage. The architects of this scheme did not foresee several years of drought, which combined with the Pak fly, wiped out DeGray's hydrilla. Largemouth bass recruitment suffered as a result. In an attempt to rejuvenate the lake, AGFC partnered in 2019 with the University of Arkansas at Pine Bluff Aquaculture and Fisheries to restore the native vegetation.

The money spent by visitors to Corps lakes on trip expenses adds to the local and national economy by supporting jobs and generating income. Visitor spending represents a sizable component of the economy in many communities around DeGray. Public's impact The benefits offered from DeGray Lake are more than just economic. By providing the public opportunities for active recreation, DeGray lake helps combat one of the most significant of the nation's health problems: lack of physical activity.
