Summary
Completed in 1980, this earth dam stands at a height of 13.7 meters and has a storage capacity of 74.7 acre-feet. The dam is situated on TR-Sweet Creek and is regulated by the Nebraska Department of Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
Despite being categorized with a low hazard potential, Blaschko Dam has a poor condition assessment as of its last inspection in June 2019. The dam spans 250 meters in length and covers a surface area of 10.1 hectares, with a drainage area of 0.31 square kilometers. While it lacks certain features like a spillway or outlet gates, the dam remains essential for its designated purposes. With its proximity to Congressional District 03 in Nebraska, the dam plays a crucial role in local water resource management and protection.
Water resource and climate enthusiasts can appreciate the intricate design and functionality of Blaschko Dam, recognizing its contribution to fire protection, agriculture, and wildlife conservation in the region. The dam's presence on Sweet Creek underscores its significance in maintaining water levels and supporting various ecosystems. Although its condition may warrant attention and potential improvements, Blaschko Dam stands as a testament to human ingenuity in harnessing natural resources for the benefit of both people and the environment.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
