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 three in particular that exhibited some need for maintenance:
the Saunders Lake outlet; the Black Lake
outlet; and the culverts under the railroad berm.
- Development, redevelopment, and
reconstruction in the subwatershed are predicted to increase runoff volumes
as well as increase nutrient and TSS loads from the watershed.
- Future development could increase the volume
and velocity of discharges conveyed by the channel from Saunders Lake
to Langdon Lake.
- The HHPLS identified two locations
where the minimum 2 foot freeboard requirement was not met for the 100-year
event: the outlet of Saunders Lake and at County Road 110 between Langdon Lake
and Lost Lake.
