3.2 Water Quantity
- Drainage is conveyed through the
subwatershed through a series of culverts and channels that should be
evaluated, monitored, and replaced or repaired as necessary to maintain
conveyance, minimize erosion, minimize hydrologic bounce, and maintain
adequate water levels in lakes and wetlands. The HHPLS and Regional Team input identified one in
particular that exhibited some need for maintenance: the culvert that
serves as the outlet from the wetland north of Schutz Lake under Highway 7.
- Development, redevelopment, and
reconstruction in the subwatershed is predicted to increase volume of
runoff as well as increase nutrient and TSS loads from the watershed, potentially
further degrading water quality in lakes, streams, and wetlands.
- Future development in the southern
subwatershed could increase volume and velocity of discharge conveyed by
the channel that drains the central part of the watershed, and could
create erosion and sediment transport issues.
- The HHPLS predicted that the outlet of
the wetland north of the lake would overtop during 100 year or larger
events. Local plans should
identify these observed or potential locations and assess whether the risk
of occasional flooding is acceptable or should be addressed.
