3.2 Water Quantity
- Dutch Lake
currently experiences fluctuations in water levels due to beaver dams and
other obstructions to the outlet.
- Drainage is conveyed through the
subwatershed through a series of culverts 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. Of
specific concern is the Game
Farm Road culvert between DL-6 and DL-7 (west
of Highway 110).
- The HHPLS identified one location
where the minimum freeboard requirement was not met for the 100 year
event: the Game Farm Road
culvert between DL-6 and DL-7 (west of Highway 110). More detail is available in the
HHPLS. Local plans should identify
this potential location and assess whether the risk of occasional flooding
is acceptable or should be addressed.
- Development, redevelopment, and
reconstruction in the subwatershed are predicted to increase nutrient and
TSS loads from the watershed as well as increase the volume of stormwater
- Future development could increase the
volume and velocity of discharges conveyed by Dutch Creek.
