Proposal for a Missouri River Basin InteragencyExpanded Plains Snow and Basin Condition
NetworkIndependent Technical Review (ITR) - (Recommendation #5):Studies to enhance data collection, forecasting, and resulting runoff from
plains snow. Suggested activities include establishment of additional permanent plains snow measurement stations (using already established snow measurement standards), focused on the development of improved historical record at permanent stations; and research on the effects of prairie soils, geomorphology, and hydrology on snowmelt runoff. Also, the Corps should work to improve collaboration with other groups that collect and analyze snow data, for example, the Community Collaborative Rain, Hail and Snow (CoCoRaHS) network.
March 2012:
"An expanded Plains snowpack monitoring system needs to be set up while memories of the floods are fresh and everyone is willing to spend the money, (SD Governor) Daugaard told top officials of the U.S. Army Corps of Engineers,"
“(USACE NWD Commander) McMahon said the corps is working with other agencies to determine how to create and fund an expanded plains snowpack monitoring system, one of the recommendations made by an expert panel that studied last summer's flooding. A more extensive system is already in place for monitoring the snowpack in the northern Rocky Mountains, he said." 2
Proposal for a Missouri River Basin Interagency
Expanded Plains Snow and Basin Condition Network
Purpose:The goal of this proposal is to present a framework for the establishment of an interagency, usable and sustainable network that will enhance the forecasting of runoff during the plains snowmelt period. This proposal is not intended to be a final plan, rather a launching point for additional discussion to include appropriate subject matter experts into developing the final plan.
Approach:This proposal involved consultation with subject matter experts from various agencies. Establishment of the plains snow network in the same manner as the mountain snow network could be established over a period of time. Initially, use of near real-time, on-the-ground snow depth and snow water equivalent (SWE) measurements made manually at regular intervals would provide necessary information in the short-term and also be extremely useful in determining long-term, possibly automated, network needs. 3
