groundwater infusions from the Blue Hole and falls cool the creek again; from the bend eastward to its mouth it is a freestone stream with a large population of stocked and wild brown trout. The 11,200 fry added to the waters each year come from the state fish hatchery north of Caledonia on the Oatka's Spring Creek tributary established in 1864 by Seth Green, the oldest such facility in the Western Hemisphere. Brown trout was first introduced to American waters from it; today the of fish produced supply almost all of the state's stocked streams. Public access to this section is extensive. The section in Oatka Creek Park is the most frequently used, since special regulations to conserve the wild trout population there allow no-kill fishing there with artificial lures year-round. Similar rules apply between October and March in the less-accessible stretch downstream of the park to Bowerman Road; during the regular season anglers are limited to two fish per day at a minimum. Black bass and northern pike have also taken flies in those waters. Access is also available from a small Scottsville village park on the south bank east of Route 251, the hundred feet on the other side of that highway and both sides of the NY 36 bridge near Wheatland Center, as well as 50 ft (15 m) on either side of county roads that cross the creek. DEC has also acquired public fishing easements on a small stretch in Mumford and much of both banks along Oatka Trail in the Town of Le Roy between Mud Creek and the unnamed northern tributary two miles (3.2 km) upstream. These allow use of the 33 feet (11 m) adjoining the river by anglers for access to the water. They are subject to regular DEC fishing regulations.
