Lake Elkhorn


Lake Elkhorn, in the Village of Owen Brown is a 37 acre lake on the Elkhorn Branch of the Little Patuxent River. George Harold Dasher for whom the neighborhood of Dasher Green is named, lived all his life in Howard County, farming the land with his brothers at Elkhorn Farms. The new lake, park and arboretum derive their name from the original Dasher farm.

Lake Elkhorn was created in 1974 by building an earth filled dam, which impounds 225 acre feet of water drawing from a watershed of about 2500 acres. A concrete spillway at one side of the dam permits controlled overflow. At the head of the lake, in what was a marsh, a silt pond with a filter dike was formed. In a cove at the lake's edge, near the Owen Brown Village Center is a major small boat dock which provides boaters with access to the lake.


Warren Raymond

This arboretum is dedicated to a friend of both the Howard County Forestry Board and of the Columbia Association. An avid musician and gardener Warren studied at Longwood Gardens to become a Certified Tree Expert and, working for the Columbia Association, became the Assistant Division Director for Open Space. Warren joined the Howard County Forestry Board in 2000 and helped with the planning of this arboretum at Lake Elkhorn. He is fondly remembered by all who knew and worked with him.

Much of the landscape at Lake Elkhorn has been left in its natural state, yet there are over fifty different species of trees around the lake path.

Sometimes called a "Blue Beech", a key feature of the Hornbeam is its beech-like blue-gray smooth bark.It is often a short shrubby tree with strangely muscular or twisted trunks and branches. These twists evolve into vertical ridges.

While related to the birches, not the beeches, the Hornbeam has a beech-like leaf which is pointed and has striking parallel veins. The main difference is that the Hornbeam leaf is doubly serrated with teeth not only at the end of the veins, but between as well.

The flowers are catkins found along the branches, not at the tip like the Hop-Hornbeam. The fruit is a small seed borne on distinctive 3-lobed bracts.

This muscle-bound looking tree has a leaf and flower similar to the Hop-Hornbeam, but the bark and trunk of the Blue Beech are dead giveaways. In autumn the American Hornbeam will turn red-orange and scarlet while the Hop-Hornbeam changes to a clear yellow.


Directions: From Route 29 take Broken Land Parkway east for about two miles. Take the second entrance into Owen Brown Village on Cradlerock Way. Lake Elkhorn can be seen to the right, opposite the village shopping center. There is parking along Cradlerock. Enjoy the trees!
