Outline
1
"The class of the gifted..."
  • The class of the gifted and talented
  • Maryland Summer Center of 2008
2
"During rain storms sediment is..."
  • During rain storms sediment is carried down the watershed into the Atkisson reservoir.
  • Development in the Winters Run watershed have created more impervious surfaces.
3
"To what extent have human..."
  • To what extent have human induced changes impacted the natural succession process in Harford Glen?
4
"Residents of the Winters Run..."
  • Residents of the Winters Run watershed.
  • Fisherman/Recreational users.
  • Building developers.
  • Harford Glen staff.
  • Users of the Bush River.
5
"To what extent has the..."
  • To what extent has the development  in the Winters Run watershed affected the growth of the deposition island in Harford Glen?
6
"PVC poles have been placed..."
  • PVC poles have been placed on the island since 1990.  Dates have been posted on poles keep track of the growth of island.
  • Due to previous studies it has been inferred that the islands may have been created by Hurricane Agnes.
  • Laws have been passed about soil erosion in America.
  • Aerial maps of the Atkisson dam has been observed to confirm that the islands are growing at an unnatural rate.
7
"Built in 1942"
  • Built in 1942
  • A back-up water supply for the army
  • The dam is 42 feet in height
  • More than 81% filled with sediment
  • Has never been dredged
  • Still owned by U.S. government
  • Watershed area above reservoir is 45.1 sq. miles
  • Is a gravity dam

9
"When water carries the soil..."
  • When water carries the soil downstream.
  • The wearing away of land or soil by the action of wind, water, or ice.
10
"There are heavy fines for..."
  • There are heavy fines for allowing things to be eroded on a building site.
  • There are different factors to control site erosion including soil type, slope of site, site erosion hazard rating, surface rock, extent and duration of site erosion, proximity of water courses and drainage lines, and sensitivity of receiving waters.

"Even though the rain varies..."
  • Even though the rain varies from year to year the island growth does not seem to correspond with rain totals.
  •  Further study is needed to determine the variable that causes rapid growth.
  • The increasing population leads to more impervious surfaces.


  • The rain varied from 30-50in. from 1990-2003.
  • The deposition island grows each year at different rates.
  • The population is growing in the Winters Run watershed.
  • INFERENCES
  • CONCLUSIONS

"Contact the army in some..."
  • Contact the army in some way (letter, phone call, e-mail) to find out what is their plan for the Atkisson reservoir.
  • Create an article about the Atkisson dam and what you can do to help with it and send it to the aegis newspaper or the bay journal.
  • Put a new PVC pole on the island to mark the 2008 point.
