Four Tulsa District, U.S. Army Corps of Engineers project offices have planned events in conjunction with National Public Lands Day, September 28. Day use fees for boat ramps and swim beaches will be waived at all Tulsa District lake offices and at Corps lakes nationwide but Kaw, Keystone, Eufaula and Fort Supply project offices are hosting volunteer cleanup events in conjunction with NPLD. Lake Eufaula's project office is hosting the second annual "Eufaula Lake Trash Bash." Volunteers may participate by boat or by land in the cleanup collaboration of Eufaula Lake and dam. The event kicks off from Lady Bird Landing at 9 a.m. Volunteers will receive free fee coupons and water safety items. Kaw Lake will focus on Eagle Watch trail, with work beginning at 8 a.m. According to Ranger Ashley Haan, "Last year during National Public Lands Day, volunteers and Corps staff were able to clean up over three miles of the Eagle View Trail, paint two picnic shelters and stain the playground equipment in Osage Campground." Keystone Lake staff will target Washington Irving South to repair the damage and debris left behind by the spring floods. "We need your help to make more progress with trail maintenance and cleaning up the day use area so we can look forward to reopening these amazing features back to the public," said Keystone Lake Ranger, Tyler Marye. Fort Supply will concentrate efforts on litter and debris removal around the shorelines and areas surrounding the lake. Their event kicks off at 9 a.m. Volunteers should meet at the group picnic shelter next to the main boat ramp. The National Park Service established National Public Lands Day in 1994 to promote environmental stewardship and use of public lands. Held annually on the fourth Saturday in September, the event has become the nation's largest single-day volunteer effort.
