In 2016, the Montana Dam Safety Program assembled a group of experts to evaluate our methodology for determining the inflow design flood for dam spillway analysis in MT. This report summarizes the groups finding and recommendations.

This report discusses research conducted by DOWL that evaluates the soil stresses that must be considered in a design when rehabilitating outlet works on small dams.

This publication developed by Morrison-Maeirle provides guidance to determine the best method to employ for reservoir drawdown. Both pumps and siphons effectively remove water from reservoirs and can provide the necessary increased capacity in emergency situations. Each site and event has unique circumstances which will determine the method best suited. This guidebook outlines a process using basic hydraulic and logistical considerations for determining the best method for reservoir drawdown. Part of this process includes outlining important factors to be used in decision making. Key topics for both pumps and siphons are explored in detail.

This publication provides guidance on the proper design and construction of chimney filters and drains.This technical note is intended to provide practical guidance for use by dam owners and engineers for the design and construction of chimney filter and drainage features for embankment dams, particularly small embankment dams. This technical note isnot intended to be an all-inclusive guide for design of filter and drain systems. Inmany instances, the document directs readers to other references that provide more detailed information. In addition, an extensive list of references on the topic is provided at the end of this document.
