Where temporary storage of water occurs on the surface, the depth and rate of rise of the water should be sufficiently low that risks are minimized for site users, especially since the temporary nature of the storage facility will mean that the public are not accustomed to its presence. A risk assessment should be undertaken of the frequency and rate of flooding to a range of inundation depths in order that public safety is not jeopardised (Ballard et al., 2015). <ref name=Ballard>Ballard, B.

Dry detention ponds can elevate the [[Stormwater Thermal Mitigation|temperature of stormwater]]. This effect can be reduced by shortening detention time (US EPA, 2021)<ref>United States EPA. 2021. Stormwater Best Management Practice. https://www.epa.gov/system/files/documents/2021-11/bmp-dry-detention-ponds.pdf</ref>, increasing canopy cover, or installing [[Stormwater Thermal Mitigation#Cooling Trenches|cooling trenches]] at the pond outlet (City of Toronto, 2015)<ref name = "CoT 2015"></ref>. Alternative stormwater controls may be better suited for areas that discharge to cold-water streams.
