The overfill is competent and drains underground into a natural storm creek about 300 yards away. This sandy stuff appears to be runoff from new roofs and sandy street stuff. *When scoping around our area, one cannot distinguish a dredged pond from an un-dredged pond.īecause our basin is a neighborhood run off catch basin, there is ample silt at the main inlet. Pond will continue to absorb neighborhood runoff which includes plenty of fertilizer and anaerobic algae killer (midge larvae / blood worms rely on anaerobic environment). The fine print on the Overlord bid reveals that, with a $500 monthly maintenance, they will spray for bugs. This will kill the fish, frogs, lizards, snakes and rip rap organic growth. *Unless we drain the pond, remove every bit of debris and scrub it with Spic n Span, there is no real way to remove bugs and bug larvae. I was able to provide the original basin specs from the sewer district, including type and quality of clay lining. Project research reveals these things: *there are probably no shipwrecks or underwater dangers, my skepticism causes me to view this as a bit of a scam.
Calling around my suburban area reveals that this project could cost up to $200k. They will not bid until they have completed the survey. They warn of dam breaks, over-fills, no flood insurance and terrible bug problems. During the sales pitch, I mentally compared this to an undercoat when buying a car. They subtract the cost of survey into the actual cost of the dredging. First, the Big Overlord Company provides a bathymetric survey. The dredging overlords sub contract to local people with proper equipment. Research reveals that suburban pond dredging is big busines$. The rationales are a) that's just how things are done and b) one lady thinks that it will stop midges.
An original resident remembers that it was dredged, but does not remember when.Others suggest that its been at least 20+ years. Long story: Pond is 35 years old, 5400 sq yards surface area, 13 feet at deepest with competent aeration fountain.
