NH HB1530

Requires landowners to notify local governing bodies, conservation commissions, and affected abutters at least 30 days before removing beaver dams or significantly lowering water levels in shared beaver impoundments (those covering or abutting another owner's land)

Mandates a public informational meeting be held at least 15 days before any dam removal or water level lowering action, with notice published in a newspaper or on the municipality's website at least 7 days in advance

Exempts emergency situations involving immediate threats to life or property from the notification and public meeting requirements

Allows installation of flow devices without a permit or the public notification process, and permits beaver dam removal without a wetlands permit if machinery doesn't enter the water and work is done gradually to prevent downstream hazards

Estimated fiscal impact of $10,000 to $100,000 per year for the Fish and Game Department to participate in informational meetings, with potential local expenditures up to $10,000 per municipality
