Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

This is an interesting one. Following the keys in Merritt R.W., Cummins, K.W., and Berg, M.B. (2019) and Jacobus et al. (2014), it keys clearly to Ephemerella. Jacobus et al provide a key to species, but some of the characteristics are tricky to interpret without illustrations. If I didn't make any mistakes, this one keys to Ephemerella mucronata, which has not previously been reported any closer to here than Montana and Alberta. The main character seems to fit well: "Abdominal terga with prominent, paired, subparallel, spiculate ridges." Several illustrations or descriptions of this holarctic species from the US and Europe seem to match, including the body length, tarsal claws and denticles, labial palp, and gill shapes. These sources include including Richard Allen's original description of this species in North America under the now-defunct name E. moffatae in Allen RK (1977) and the figures in this description of the species in Italy.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Thought the following news blurb might be of interest to some folks around Indiana, Ohio, Kentucky. I think it illustrates what can happen when people work together.


Brookville Lake tailwater will be stocked with federal Brown Trout
------------------------------------------------

The Indiana Department of Natural Resources is sponsoring a community trout stocking
in Brookville on May 15 at 2 p.m. EDT.

The DNR will be trucking in 2,600 9-inch brown trout provided by the Wolf Creek
National Fish Hatchery near Jamestown, Ky. Brookville Lake is eligible to receive
federal fish because it is a federal flood control project.

The fish will be released into the East Fork of the Whitewater River below
Brookville Lake. The public is invited to attend and assist in stocking the fish.

A two-mile stretch of the East Fork of the Whitewater River below the 5,260-acre
reservoir at the edge of Brookville in Franklin County has provided Indiana anglers
with rainbow trout fishing for more than 30 years.

The DNR stocks 1,500 rainbow trout into the river each spring. Most of these fish
are harvested in the first weeks following the opening of the trout season on the
last Saturday in April.

In 2000, the Central Indiana Chapter of Trout Unlimited led an effort to partner
with the DNR in developing the tailwater into a trout fishing destination.

With assistance from several other conservation groups and businesses, the chapter
has purchased brown trout annually and released them into the cool waters below the
reservoir under stocking permits issued by DNR.

"These brown trout survived and displayed excellent growth," said DNR fisheries
chief Bill James. "Special regulations that limited brown trout harvest to one fish
per day with a minimum size limit of 18 inches were put in place to encourage more
and larger trout. These strategies are working as anglers are now catching brown
trout that surpass 20 inches and four pounds."

"This community fish stocking is an excellent example of how conservation partners
can come together to improve a resource and create new public outdoor
opportunities," said DNR Director Robert Carter. "We appreciate the efforts by
anglers, conservation groups, the U.S. Fish and Wildlife Service, the Corps of
Engineers, the local community and everyone else who supports and values this
beautiful stretch of stream."

Trout anglers must have a valid fishing license and trout/salmon stamp. The daily
bag limit from Brookville Lake's tailwaters is five trout, of which no more than one
may be a brown trout. Brown trout must be at least 18 inches long to be possessed.
The minimum size limit on rainbow trout is 7 inches.

Stocking location
