Characterization of Miller Run and Conceptual Plan for Watershed Restoration
UNIV 298 Spring 2009 + Miller Run: An Overview + Miller Run Statistics
80% of Miller Run is owned by Bucknell.
The runoff from the new housing developments also contribute to the stream.
Length of Stream: 2,000m
Percent Forest: 13.1% (The Grove and the Golf Course)
Percent Urban: 37.5% (Buildings and Roads)
Channelized: 75-100%
50% Rip-rap

Water samples were also taken manually during normal flow and high flow events, and analyzed for chemical composition.

Reasons for Biotic Sampling:
Aquatic macroinvertebrates are highly variable in their sensitivity to water pollution. These differences can be used by biologists to evaluate the overall health of a stream.
The link between fish species composition and water quality provides an important assessment of stream ecosystem health.
Algae analyses allow us to determine gain information about the biomass of algae, which is related to water chemistry and conditions of riparian vegetation. + Macroinvertebrates + Macroinvertebrate Results IBI Score of Miller Run Compared to Impairment Level • IBI Scores are used by the DEP to measure the degree of a stream’s 100 impairment. 80 60

Proposed Solutions for the Lasting Health of Miller Run +
Flood control – Stormwater management, Water retention, low flow augmentation, out-of-channel solutions
Aesthetic appeal – Appropriate stream landscaping, recreational (walking/biking) & meditation space, Bucknell as an example, community green space
Environmental education – Watershed management, “outdoor classroom”, research opportunities Ecological health and sustainability – Maintain year-round flow, provide habitat for target species, encourage native species growth
Channel sustainability – Space for migration/channel evolution, structure/obstruction removal or replacement, bank stability measures, floodplain reconnection Bucknell is what we call an impermeable jungle.
The campus is covered with ugly asphalt walkways and parking lots and large buildings which do not have efficient storm water management structures.
This needs to change to help replenish the ground water and reduce runoff. •Buildings and storm drains feed directly+ into Miller Run.
•Large amount of storm water produced.
•Explains why downstream peaks before upstream.
•Structures that could help cut down on surplus of water.
•Porous Pavements
o Asphalt, concrete, and block pavers
•Infiltration trenches
•Rain Gardens Permeable Pavements + •Pavements can be placed on slopes no greater than 5-20 degrees, which is a great deal of campus.
•Greatly reduce runoff.
•To keep pores clean walkways should be maintained.
•Some pavements more pleasing to the eye than others, but all are better than the ugly asphalt now. + Stepped Infiltration Trenches Possible+ Sites + Roof Runoff feeding into Infiltration Trenches + Possible Sites + Rain Garden + Rain Garden +Possible Sites + +
